Phineas Gage


Phineas P. Gage was an American railroad construction foreman remembered for his improbable survival of an accident in which a large iron rod was driven completely through his head, destroying much of his brain's left frontal lobe, and for that injury's reported effects on his personality and behavior over the remaining 12 years of his lifeeffects sufficiently profound that friends saw him as "no longer Gage."
Long known as the "American Crowbar Case"once termed "the case which more than all others is to excite our wonder, impair the value of prognosis, and even to subvert our physiology| doctrines"Phineas Gage influenced 19th-century discussion about the mind and brain, debate on cerebral, and was perhaps the first case to suggest the brain's role in, and that damage to specific parts of the brain might induce specific mental changes.
Gage is a fixture in the curricula of neurology, psychology, and neuroscience, one of "the great medical curiosities of all time" and "a living part of the medical folklore" frequently mentioned in books and scientific papers; he even has a minor place in popular culture. Despite this celebrity, the body of established fact about Gage and what he was like is small, which has allowed "the fitting of almost any theory to the small number of facts we have"Gage acting as a "Rorschach inkblot" in which proponents of various conflicting theories of the brain all saw support for their views. Historically, published accounts of Gage have almost always severely exaggerated and distorted his behavioral changes, frequently contradicting the known facts.
A report of Gage's physical and mental condition shortly before his death implies that his most serious mental changes were temporary, so that in later life he was far more functional, and socially far better adapted, than in the years immediately following his accident. A social recovery hypothesis suggests that his work as a stagecoach driver in Chile fostered this recovery by providing daily structure which allowed him to regain lost social and personal skills.

Life

Background

Gage was the first of five children born to Jesse Eaton Gage and Hannah Trussell Gage of Grafton County, New Hampshire. Little is known about his upbringing and education beyond that he was literate.
Town doctor John Martyn Harlow described Gage as "a perfectly healthy, strong and active young man, twenty-five years of age, nervo-bilious temperament, in height, average weight, possessing an iron will as well as an iron frame; muscular system unusually well developedhaving had scarcely a day's illness from his childhood to the date of injury".
Gage may have first worked with explosives on farms as a youth, or in nearby mines and quarries. He is known to have worked on construction of the Hudson River Railroad near Cortlandt Town, New York, and by the time of his accident he was a blasting foreman on railway construction projects. His employers' "most efficient and capable foreman ... a shrewd, smart business man, very energetic and persistent in executing all his plans of operation", he had even commissioned a custom-made a large iron rodfor use in setting explosive charges.

Accident

On September 13, 1848, Gage was for the Rutland Railway| south of the village of Cavendish, Vermont|. Setting a blast entailed boring a hole deep into an of rock; adding blasting powder| and a fuse; then using the tamping iron to pack sand, clay, or other inert material into the hole above the powder in order to contain the blast's energy and direct it into surrounding rock.
As Gage was doing this around 4:30 p.m., his attention was attracted by his men working behind him.
Looking over his right shoulder, and bringing his head into line with the blast hole, Gage opened his mouth to speak; in that same instant the tamping iron sparked against the rock and the powder exploded. Rocketed from the hole, the tamping iron in diameter, long, and weighing entered the left side of Gage's face in an upward direction, just forward of the angle of the lower jaw. Continuing upward outside the upper jaw and possibly fracturing the cheekbone, it passed behind the left eye, through the left side of the brain, then completely out the top of the skull through the frontal bone.
Despite 19th-century references to Gage as the "American Crowbar Case", his tamping iron did not have the bend or claw with the term crowbar; rather, it was simply a pointed cylinder something like a javelin, round and fairly smooth:
The tamping iron landed point-first some away, "smeared with blood and brain".
Gage was thrown onto his back and gave some brief convulsions of the arms and legs, but spoke within a few minutes, walked with little assistance, and sat upright in an oxcart for the ride to his lodgings in town. About 30 minutes after the accident physician Edward H. Williams, finding Gage sitting in a chair outside the hotel, was greeted with "one of the great understatements of medical history":
Harlow took charge of the case around 6 p.m.:

Treatment and convalescence

With Williams' assistance Harlow shaved the scalp around the region of the tamping iron's exit, then removed coagulated blood, small bone fragments, and "an ounce or more" of protruding brain. After probing for foreign bodies and replacing two large detached pieces of bone, Harlow closed the wound with adhesive straps, leaving it partially open for drainage; the entrance wound in the cheek was bandaged only loosely, for the same reason. A wet was applied, then a nightcap, then further bandaging to secure these dressings. Harlow also dressed Gage's hands and forearms and ordered that Gage's head be kept elevated.
Late that evening Harlow noted: "Mind clear. Constant agitation of his legs, being alternately retracted and extended... Says he 'does not care to see his friends, as he shall be at work in a few days.
Despite his own optimism, Gage's convalescence was long, difficult, and uneven. Though recognizing his mother and unclesummoned from Lebanon, New Hampshire, 30 miles away on the morning after the accident, on the second day, he "lost control of his mind, and became decidedly delirious". By the fourth day, he was again "rational ... knows his friends", and after a week's further improvement Harlow entertained, for the first time, the thought "that it was possible for Gage to recover ... This improvement, however, was of short duration."
Beginning 12 days after the accident, Gage was semi-comatose, "seldom speaking unless spoken to, and then answering only in monosyllables", and on the 13th day Harlow noted, "Failing strength ... coma deepened; the globe of the left eye became more protuberant, with pushing out rapidly from the internal canthus from the wounded brain, and coming out at the top of the head." By the 14th day, "The exhalations from the mouth and head horribly. Comatose, but will answer in monosyllables if aroused. Will not take nourishment unless strongly urged. The friends and attendants are in hourly expectancy of his death, and have his coffin and clothes in readiness."
Galvanized to action, Harlow "cut off the fungi which were sprouting out from the top of the brain and filling the opening, and made free application of caustic to them. With a scalpel I laid open the and immediately there were discharged eight ounces of ill-conditioned pus, with blood, and excessively fetid."
On the 24th day, Gage "succeeded in raising himself up, and took one step to his chair". One month later, he was walking "up and down stairs, and about the house, into the ", and while Harlow was absent for a week Gage was "in the street every day except Sunday", his desire to return to his family in New Hampshire being "uncontrollable by his friends ... he went without an overcoat and with thin boots; got wet feet and a chill". He soon developed a fever, but by mid-November he was "feeling better in every respect walking about the house again". Harlow's prognosis at this point: Gage "appears to be in a way of recovering, if he can be controlled".
By November 25, Gage was strong enough to return to his parents' home in Lebanon, New Hampshire, traveling there in a "close carriage". Though "quite feeble and thin ... weak and childish" on arriving, by late December he was "riding out, improving both mentally and physically", and by February 1849 he was "able to do a little work about the horses and barn, feeding the cattle etc. as the time for ploughing came he was able to do half a day's work after that and bore it well". In August his mother told an inquiring physician that his memory seemed somewhat impaired, though slightly enough that a stranger would not notice.

Injuries

In April 1849, Gage returned to Cavendish and visited Harlow, who noted at that time loss of vision, and ptosis, of the left eye, a large scar on the forehead and
Gage's rearmost left upper molar, adjacent to the point of entry through the cheek, was also lost.
Though a year later some weakness remained, Harlow wrote that "physically, the recovery was quite complete during the four years immediately succeeding the injury".

New England and New York (18491852)

the Professor of Surgery at Harvard Medical School, brought Gage to Boston for several weeks and, after satisfying himself that the tamping iron had actually passed through Gage's head, presented him to a meeting of the Boston Society for Medical Improvement and to the medical school class.
Unable to reclaim his railroad job Gage was for a time "a kind of living museum exhibit" at Barnum's American Museum in New York City. Advertisements have also been found for public appearances by Gagewhich he may have arranged and promoted himselfin New Hampshire and Vermont, supporting Harlow's statement that Gage made public appearances in "most of the larger New England towns".
For about 18 months, he worked for the owner of a stable and coach service in Hanover, New Hampshire.

Chile and California (18521860)

In August 1852, Gage was invited to Chile to work as a long-distance stagecoach driver there, "caring for horses, and often driving a coach heavily laden and drawn by six horses" on the ValparaísoSantiago route. After his health began to fail in mid-1859, he left Chile for San Francisco, arriving "in a feeble condition, having failed very much since he left New Hampshire ... Had many ill turns while in Valparaiso, especially during the last year, and suffered much from hardship and exposure." In San Francisco he recovered under the care of his mother and sister, who had relocated there from New Hampshire around the time he went to Chile. Then, "anxious to work", he found employment with a farmer in Santa Clara.
In February 1860, Gage began to have epileptic seizures. He lost his job, and as the seizures increased in frequency and severity he "continued to work in various places could not do much".

Death and exhumation

On May 18 Gage "left Santa Clara and went home to his mother. At 5 o'clock, A.M., on the 20th, he had a severe. The family physician was called in, and bled him. The were repeated frequently during the day and night," and he died in status , in or near San Francisco,
late on May 21, 1860. He was buried in San Francisco's Lone Mountain Cemetery.
all trace of , and had well nigh abandoned all of ever hearing from him again") somehow learned that Gage had died in California, and made contact with his family there. At Harlow's request the family had Gage's skull exhumed, then personally delivered it to Harlow, who was by then a prominent physician, and civic leader in Woburn, Massachusetts.
About a year after the accident, Gage had given his tamping iron to Harvard Medical School's Warren Anatomical Museum, but he later reclaimed it and made what he called "my iron bar" his "constant companion during the remainder of his life";
now it too was delivered by Gage's family to Harlow. After studying them for a triumphal 1868 retrospective paper on Gage Harlow redeposited the ironthis time with the skullin the Warren Museum, where they remain on display today.
The tamping iron bears the following inscription, commissioned by Bigelow in conjunction with the iron's original deposit in the Museum :
The date Jan 6 1850 falls within the period during which Gage was in Boston under Bigelow's observation.
In 1940 Gage's headless remains were moved to Cypress Lawn Memorial Park as part of a mandated relocation of San Francisco's cemeteries to outside city limits.

Mental changes and brain damage

Gage may have been the first case to suggest the brain's role in determining personality and that damage to specific parts of the brain might induce specific personality changes, but the nature, extent, and duration of these changes have been difficult to establish. Only a handful of sources give direct information on what Gage was like, the mental changes published after his death were much more dramatic than anything reported while he was alive, and few sources are explicit about the period of Gage's life to which each of their various descriptions of him is meant to apply.

Early observations (1849–1852)

Harlow described the pre-accident Gage as hard-working, responsible, and "a great favorite" with the men in his charge, his employers having regarded him as "the most efficient and capable foreman in their employ"; he also took pains to note that Gage's memory and general intelligence seemed unimpaired after the accident, outside the periods of delirium. Nonetheless these same employers, after Gage's accident, "considered the change in his mind so marked that they could not give him his place again":
This description is from Harlow's observations set down soon after the accident, but Harlowperhaps hesitant to describe his patient negatively while he was still alivedelayed publishing it until 1868, after Gage had died and his family had supplied "what we so much desired to see".
In the interim, Harlow's 1848 report, published just as Gage was emerging from his convalescence, merely hinted at psychological symptoms:
But after Bigelow termed Gage "quite recovered in faculties of body and mind" with only "inconsiderable disturbance of function", a rejoinder in the American Phrenological Journal
was apparently based on information anonymously supplied by Harlow. Pointing out that Bigelow's extensive verbatim quotations from Harlow's 1848 papers omitted Harlow's promise to follow up with details of Gage's "mental manifestations", Barker explains Bigelow's and Harlow's contradictory evaluations by differences in their educational backgrounds, in particular their attitudes toward cerebral localization and phrenology :
A reluctance to ascribe a biological basis to "higher mental functions" may have been a further reason Bigelow discounted the behavioral changes in Gage which Harlow had noted.

Later observations (18581859)

In 1860, an American physician who had known Gage in Chile in 1858 and 1859 described him as still "engaged in stage driving in the enjoyment of good health, with no impairment whatever of his mental faculties". Together with the fact that Gage was hired by his employer in advance, in New England, to become part of the new coaching enterprise in Chile, this implies that Gage's most serious mental changes had been temporary, so that the "fitful, irreverent ... capricious and vacillating" Gage described by Harlow immediately after the accident became, over time, far more functional and socially far better adapted.
Macmillan writes that this conclusion is reinforced by the responsibilities and challenges associated with stagecoach work such as that done by Gage in Chile, including the requirement that drivers "be reliable, resourceful, and possess great endurance. But above all, they had to have the kind of personality that enabled them to get on well with their passengers." A day's work for Gage meant "a 13-hour journey over 100 miles of poor roads, often in times of political instability or frank revolution. All thisin a land to whose language and customs Phineas arrived an utter strangermilitates as much against permanent disinhibition as do the extremely complex sensory-motor and cognitive skills required of a coach driver."

Social recovery

Macmillan writes that this contrastbetween Gage's early, versus later, post-accident behaviorreflects his " from the commonly portrayed impulsive and uninhibited person into one who made a reasonable 'social recovery, citing persons with similar injuries for whom "someone or something gave enough structure to their lives for them to relearn lost social and personal skills":
According to contemporary accounts by visitors to Chile, Gage would have had to
En route :
Thus Gage's stagecoach work"a highly structured environment in which clear sequences of tasks were required contingencies requiring foresight and planning arose daily"resembles rehabilitation regimens first developed by Soviet neuropsychologist Alexander Luria for the reestablishment of self-regulation in World War II soldiers suffering frontal lobe injuries.
A neurological basis for such recoveries may be found in emerging evidence "that damaged Neural pathway| tracts may re-establish their original connections or build alternative pathways as the brain recovers" from injury. Macmillan adds that if Gage made such a recoveryif he eventually "figured out how to live" despite his injurythen it "would add to current evidence that rehabilitation can be effective even in difficult and long-standing cases"; and if Gage could achieve such improvement without medical supervision, "what are the limits for those in formal rehabilitation programs?" As author Sam Kean put it, "If even Phineas Gage bounced backthat's a powerful message of hope."

Exaggeration and distortion of mental changes

Macmillan's analysis of scientific and popular accounts of Gage found that they almost always distort and exaggerate his behavioral changes well beyond anything described by anyone who had direct contact with him, concluding that the known facts are "inconsistent with the common view of Gage as a boastful, brawling, foul-mouthed, dishonest useless drifter, unable to hold down a job, who died penniless in an institution". In the words of Barker, "As years passed, the case took on a life of its own, accruing novel additions to Gage's story without any factual basis". Even today "Most commentators still rely on hearsay and accept what others have said about Gage, namely, that after the accident he became a psychopath"; Grafman has written that "the details of social cognitive impairment have occasionally been inferred or even embellished to suit the enthusiasm of the story teller";
and Goldenberg calls Gage "a blank sheet upon which authors can write stories which illustrate their theories and entertain the public".
For example, Harlow's statement that Gage "continued to work in various places; could not do much, changing often, and always finding something that did not suit him in every place he tried" refers only to Gage's final months, after convulsions had set in. But it has been misinterpreted as meaning that Gage never held a regular job after his accident, "was prone to quit in a capricious fit or be let go because of poor discipline", "never returned to a fully independent existence", "spent the rest of his life living miserably off the charity of others and traveling around the country as a sideshow freak", and died "in careless dissipation". In fact, after his initial post-recovery months spent traveling and exhibiting, Gage supported himselfat a total of just two different jobsfrom early 1851 until just before his death in 1860.
Other behaviors ascribed, by various authors, to the post-accident Gage that are either unsupported by, or in contradiction to, the known facts include the following:
None of these behaviors is mentioned by anyone who had met Gage or even his family,
and as Kotowicz put it, "Harlow does not report a single act that Gage should have been ashamed of." Gage is "a great story for illustrating the need to go back to original sources", writes Macmillan, most authors having been "content to summarize or paraphrase accounts that are already seriously in error".
Nonetheless "the telling of story has increased interest in understanding the enigmatic role that the frontal lobes play in behavior and personality", and Ratiu has said that in teaching about the frontal lobes, an anecdote about Gage is like an "ace your sleeve. It's just like whenever you talk about the French Revolution you talk about the guillotine, because it's so cool."
Benderly suggests that instructors use the Gage case to illustrate the importance of critical thinking.

Extent of brain damage

In addition, Ratiu et al. noted that the hole in the base of the cranium has a diameter about half that of the iron itself; combining this with the hairline fracture beginning behind the exit region and running down the front of the skull, they concluded that the skull "hinged" open as the iron entered from below, then was pulled closed by the resilience of soft tissues once the iron had exited through the top of the head.
Van Horn et al. concluded that damage to Gage's white matter was as or more significant to Gage's mental changes than cerebral cortex damage. Thiebaut de Schotten et al. estimated white-matter damage in Gage and two other case studies, concluding that these patients "suggest that social behavior, language, and memory depend on the coordinated activity of different regions rather than single areas in the frontal or temporal lobes."

Factors favoring Gage's survival

Harlow saw Gage's survival as demonstrating "the wonderful resources of the system in enduring the shock and in overcoming the effects of so frightful a lesion, and as a beautiful display of the recuperative powers of nature", and listed what he saw as the circumstances favoring it:
For Harlow's description of the pre-accident Gage, see § Background, above.
Despite its very large diameter and mass the tamping iron's relatively low velocity drastically reduced the energy available to compressive and concussive "shock waves".
Harlow continued:
Barker writes that " from falls, horse kicks, and gunfire, were well known in preCivil War America every contemporary course of lectures on surgery described the diagnosis and treatment" of such injuries. But to Gage's benefit, surgeon Joseph Pancoast had performed "his most celebrated operation for head injury before Harlow's medical class, to drain the pus, resulting in temporary recovery. Unfortunately, symptoms recurred and the patient died. At autopsy, reaccumulated pus was found: granulation tissue had blocked the opening in the dura." By keeping the exit wound open, and elevating Gage's head to encourage drainage from the cranium into the sinuses, Harlow "had not repeated Professor Pancoast's mistake".
Finally,
Precisely what Harlow's "several reasons" were is unclear, but he was likely referring, at least in part, to the understanding that injuries to the front of the brain are less dangerous than those to the rear, because the latter frequently interrupt vital functions such as breathing and circulation. For example, surgeon James Earle wrote in 1790 that "a great part of the cerebrum may be taken away without destroying the animal, or even depriving it of its faculties, whereas the cerebellum will scarcely admit the smallest injury, without being followed by mortal symptoms."
Ratiu et al. and Van Horn et al. both concluded that the tamping iron passed left of the superior sagittal sinus and left it intact, both because Harlow does not mention loss of cerebrospinal fluid through the nose, and because otherwise Gage would almost certainly have suffered fatal blood loss or air embolism.
Harlow's moderate use of emetics, purgatives, and bleeding would have "produced dehydration with reduction of intracranial pressure may have favorably influenced the outcome of the case", according to Steegmann.
As to his own role in Gage's survival, Harlow merely averred, "I can only say ... with good old Ambroise Paré, I him, God healed him", but Macmillan calls this self-assessment far too modest. Noting that Harlow had been a "relatively inexperienced local physician ... graduated four and a half years earlier", Macmillan's discussion of Harlow's "skillful and imaginative adaptation conservative and progressive elements from the available therapies to the particular needs posed by Gage's injuries" emphasizes that he "did not apply rigidly what he had learned", for example foregoing an exhaustive search for bone fragments and applying caustic to the "fungi" instead of excising them or forcing them into the wound.

Early medical attitudes

Skepticism

"A distinguished Professor of Surgery in a distant city", Harlow continued, had even dismissed Gage as a "Yankee invention".
According to the Boston Medical and Surgical Journal it was the 1850 report on Gage by BigelowHarvard's Professor of Surgery and "a majestic and figure on the medical scene of those times"that "finally succeeded in forcing authenticity upon the credence of the as could hardly have been done by any one in whose sagacity and surgical knowledge his had any less confidence". Noting that, "The leading feature of this case is its This is the sort of accident that happens in the pantomime at the theater, not elsewhere", Bigelow emphasized that though "at first wholly skeptical, I have been personally convinced".
Nonetheless though "the nature of injury and its reality are now beyond doubt ... Ihave received a letter within a month to prove that ... the accident could not have happened."

Standard for other brain injuries

As the reality of Gage's accident and survival gained credence, it became "the standard against which other injuries to the brain were judged", and it has retained that status despite competition from a growing list of other unlikely-sounding brain-injury accidents, including encounters with axes, bolts, low bridges, exploding firearms, a revolver shot to the nose, other tamping irons, and falling Eucalyptus branches.
For example, after a miner survived traversal of his skull by a gas pipe in diameter his physician invoked Gage as the "only case comparable with this, in the amount of brain injury, that I have seen reported".
Often these comparisons carried hints of humor, competitiveness, or both. The Boston Medical and Surgical Journal, for example, alluded to Gage's astonishing survival by referring to him as "the patient whose cerebral organism had been comparatively so little disturbed by its abrupt and intrusive visitor"; and a Kentucky doctor, reporting a patient's survival of a gunshot through the nose, bragged, "If you can send a tamping bar through a fellow's brain and not kill him, I guess there are not many can shoot a bullet between a man's mouth and his brains, stopping just short of the medulla oblongata, and not touch either."
Similarly, when a lumbermill foreman returned to work soon after a saw cut into his skull from just between the eyes to behind the top of his head, his surgeon termed the case "second to none reported, save the famous tamping-iron case of Dr. Harlow", though apologizing that "I cannot well gratify the desire of my professional brethren to possess skull, until he has no further use for it himself."
As these and other remarkable brain-injury survivals accumulated, the Boston Medical and Surgical Journal pretended to wonder whether the brain has any function at all: "Since the antics of iron bars, gas pipes, and the like skepticism is discomfitted, and dares not utter itself. Brains do not seem to be of much account now-a-days." The Transactions of the Vermont Medical Society was similarly facetious: The times have been,' says Macbeth, 'that when the brains were out the man would die. But now they rise again.' Quite possibly we shall soon hear that some German professor is it."

Theoretical misuse

Though Gage is considered the "index case for personality change due to frontal lobe damage", the uncertain extent of his brain damage and the limited understanding of his behavioral changes render him "of more historical than neurologic interest". Thus, Macmillan writes, "Phineas' story is worth remembering because it illustrates how easily a small stock of facts becomes transformed into popular and scientific myth", the paucity of evidence having allowed "the fitting of almost any theory to the small number of facts we have". A similar concern was expressed as early as 1877, when British neurologist David Ferrier complained that, "In investigating reports on diseases and injuries of the brain, I am constantly being amazed at the inexactitude and distortion to which they are subject by men who have some pet theory to support. The facts suffer so frightfully ..."
More recently, neurologist Oliver Sacks refers to the "interpretations and misinterpretations from 1848 to the present",
and Jarrett discusses the use of Gage to promote "the myth, found in hundreds of psychology and neuroscience textbooks, plays, films, poems, and YouTube skits Personality is located in the frontal lobes... and once those are damaged, a person is changed forever."

Cerebral localization

In the 19th-century debate over whether the various mental functions are or are not localized in specific regions of the brain, both sides managed to enlist Gage in support of their theories. For example, after Eugene Dupuy wrote that Gage proved that the brain is not localized Ferrier replied by using Gage to support his thesis that the brain is localized.

Phrenology

Throughout the 19th century, adherents of phrenology contended that Gage's mental changes stemmed from destruction of his mental "organ of "as phrenologists saw it, the part of the brain responsible for "goodness, benevolence, the gentle character ... to dispose man to conduct himself in a manner conformed to the maintenance of social order"and/or the adjacent "organ of "related to religion and God, and respect for peers and those in authority.
Harlow wrote that Gage, during his convalescence, did not "estimate size or money accurately would not take $1000 for a few pebbles" and was not particular about prices when visiting a local store; by these examples Harlow may have been implying damage to phrenology's "Organ of Comparison".

Psychosurgery and lobotomy

It is frequently asserted that what happened to Gage played a role in the later development of various forms of psychosurgeryparticularly lobotomyor even that Gage's accident constituted "the first lobotomy". Aside from the question of why the unpleasant changes usually attributed to Gage would inspire surgical imitation, there is no such link, according to Macmillan:

Somatic marker hypothesis

, in support of his somatic marker hypothesis, draws parallels between behaviors he ascribes to Gage and those of modern patients with damage to the orbitofrontal cortex and amygdala. But Damasio's depiction of Gage has been severely criticized, for example by Kotowicz:
As Kihlstrom put it, "any modern commentators exaggerate the extent of Gage's personality change, perhaps engaging in a kind of retrospective reconstruction based on what we now know, or think we do, about the role of the frontal cortex in self-regulation."
Macmillan gives detailed criticism of Antonio Damasio's various presentations of Gage.

Portraits

Two daguerreotype portraits of Gage, identified in 2009 and 2010, are the only of him known other than a plaster head cast taken for Bigelow in late 1849.
The first portrait shows a "disfigured yet still-handsome" Gage with left eye closed and scars clearly visible, "well dressed and confident, even proud" and holding his iron, on which portions of its inscription can be made out.
The second portrait, copies of which are in the possession of two branches of the Gage family, shows Gage in a somewhat different pose wearing the same waistcoat and possibly the same jacket, but with a different shirt and tie.
Authenticity of the portraits was confirmed by overlaying the inscription on the tamping iron, as seen in the portraits, against that on the actual tamping iron, and matching the subject's injuries to those preserved in the head cast. However, about when, where, and by whom the portraits were taken nothing is known, except that they were created no earlier than January 1850, on different occasions, and are likely by different photographers.
The portraits support other evidence that Gage's most serious mental changes were temporary. "That was any form of vagrant following his injury is belied by these remarkable images", wrote Van Horn et al. "Although just one picture," Kean commented in reference to the first image discovered, "it exploded the common image of Gage as a dirty, disheveled misfit. This Phineas was proud, well-dressed, and disarmingly handsome."
