Gaston was born either in Orthez or Foix, the eldest son of Gaston II/IX. As the lord's eldest son, he was given the name, Gaston. He later adopted Fébus as a nickname. In its classic spelling, Phoebus, it is one of the names of the sun-god, Apollo, and is apt because of Gaston Fébus's golden hair. His native language was Gascon, but he was also fluent in French. He wrote a treatise on hunting in French, and an Occitan song, Se Canta, has been ascribed to him. One contemporary chronicler, Jean Froissart, records that he "very willingly spoke to me not in his native Gascon but in proper and elegant French".
Count of Foix
Béarn had passed to the county of Foix in 1290. Fébus paid homage to the French king for his own county, but starting in 1347 he refused to give homage for Béarn, which he claimed as an independent fief, with its chief seat his stronghold at Pau, a site that had been fortified by the 11th century, which was later made the official capital of Béarn in 1464. Starting in 1374, court minutes in the sovereign viscounty were dated with reference to the lord of Béarn. He established international diplomatic relations with Navarre, Castile and Aragon, taking advantage to a large extent of the weakness of the French crown. He started a policy of rapprochement to the realms to the south of the Pyrenees. He, for example, married Agnes, daughter of Philip III and Joan II of Navarre, with the acquiescence of the French king Philip VI. While Gaston eventually repudiated Agnes, he pursued the establishment of a Pyrenean realm under his leadership, and thus secure the control of the thriving commercial route of Toulouse-Bayonne. His intent to reinforce authority across all the area was halfhearted due to economic constraints. Although he designated the king of France as his successor, eventually that did not happen, since the newly established Estates-General of Béarn prevented it. He was succeeded as count of Foix and sovereign viscount of Béarn by Mathieu of Foix-Castelbon.
A fortune won in battle
The House of Béarn-Foix was engaged in a long running feud with the House of Armagnac. In 1362, a battle was fought between the two noble houses at Launac. Fébus was victorious and succeeded in capturing his chief rivals, whom he ransomed for a vast fortune of at least 600,000 florins. This money was stored in the Moncade tower in Orthez, where Fébus also created a gallery of portraits and military trophies to commemorate the event.
Castles
The constructions of Gaston Fébus all have in common the same plan whatever its surface and its location. The plan is as follows: a polygonal enclosure to which are built buildings forming an interior courtyard, a quadrangular tower straddling the curtain wall, sometimes a second tower, as well as a ditch spanned by a drawbridge.
Records of Jean Froissart
In late 1388, the chronicler, Jean Froissart, visited the County of Foix and recorded the splendour of Fébus' court at Orthez. He noted that Fébus describes the three "special delights" of his life as "arms, love and hunting".
''Livre de chasse'' (Book of the Hunt)
Fébus was one of the greatest huntsmen of his day, and hunted his entire life – he died of a stroke while washing his hands after returning from a bear hunt. His Livre de chasse was written between 1387–1389 and dedicated to Philip the Bold, Duke of Burgundy. Recorded in the book are different stages of hunting different animals, as well as describing animal behavior, offering advice to less well-off gentry about how to enjoy hunting without bankrupting themselves, and is even sympathetic to the peasant poacher because he too has the hunting instinct. It is the classic treatise on Medieval hunting, and was described by scholar, Hannele Klemettilä considers it, as "one of the most influential texts of its era". Some forty-four 15th and 16th century illuminated manuscripts survive, the most famous being that held by the Bibliothèque nationale de France, which has exquisite miniatures, illustrating the hunt.
As Jean Froissart records, Fébus was betrayed by his son who also bore the dynastic name, Gaston, and who tried to kill his father using poison given to him by Charles II of Navarre. Fébus caught his son in the act and imprisoned him. In a subsequent violent quarrel, Fébus stabbed his son, who died. Following Gaston's death, Fébus had no legitimate descendants. In 1393, in Paris at a masquerade given by the Queen of France, Isabeau of Bavaria, one of Gaston Fébus's four recorded illegitimate sons, Yvain de Foix, was burned to death when his costume, along with the costumes of four others, caught fire from a torch at the Bal des Ardents.

Popular Culture
In 1839, Alexandre Dumas published a long story taking Fébus as its central character, in his novel Acté. In the 20th century, the novel by Myriam and Gaston de Béarn, La Vie fabuleuse de Gaston Phœbus, was a great success. This romantic trilogy was adapted to television in 1978 in Gaston Fébus: the Lion of the Pyrenees. In March 2020, the ethnologist and ethnographer Emmanuel Larrouturou revealed that the calligraphy of Gaston Fébus' signature is an ingenious graphic device revealing, by superimposing loose sheets, various forms related to totemism.
