Sodasa reigned during the 1st century CE, and also took the title of Great Satrap at one point, probably in the area of Mathura as well, but possibly under the suzerainty of the Indo-Parthian king Gondophares. At the same time the Indo-Scythian Bhadayasa ruled in the eastern Punjab. There were numerous cultural and political exchanges between the Indo-Scythians of the northwest and those of Mathura. Sodasa may have been a contemporary of the Western KshatrapaNahapana and the Indo-Parthian Gondophares. The Indo-Parthians may have destabilized Indo-Scythian rule in northern India, but there are no traces of Indo-Parthian presence in Mathura. Sodasa may have been displaced in Mathura by the Kushan ruler Vima Kadphises, who erected a throne in his name in Mathura, but nothing is known of these interactions. At Mathura, Sodasa is the last of the Indo-Scythians to have left coins. Later, under Kanishka, son of Vima Kadphises, the Great Satrap Kharapallana and the Satrap Vanaspara are said to have ruled in Mathura with Kanishka as suzerain, pointing to continued Indo-Scythian rule under Kushan suzerainty as least until the time of Kanishka.
Inscriptions
Numerous inscriptions from Mathura mentioning Sodasa's rule are known. The Mirzapur village inscription refers to the erection of a water tank by Mulavasu and his consort Kausiki during the reign of Sodasa, assuming the title of "Svami Mahakshatrapa ". The Mathura lion capital mentions the reign of his father and predecessor Rajuvula as Mahaksatrapa while Sodasa is referred to as Ksatrapa. Sodasa probably also dedicated the Mora Well Inscription, were he presents himself as the son of Rajuvula. A large stone slab, the Kankali Tila tablet of Sodasa, discovered in Kankali in the area of Mathura, bears a three-line epigraph mentioning that in the year 42 or 72 of "Lord Mahaksatrapa Sodasa," a monument for worship was set up by a certain Amohini. A recent date for Sodasa's reign was given as 15 CE, meaning that the regnal date of the inscription would start from the Vikrama era. This would put the long reign of his father Rajuvula in the last quarter of the 1st century BCE, which is probable. Another inscription of Sodasa in Mathura records the gifts of a Brahman named Gajavara of the Segrava-gotra during the time of Saudasa the Great Satrap of the lord of tanks called Kshayawada, as well as a western tank, a well, a garden, and a pillar.
Coinage
Sodasa's coins have been found in Mathura only, suggesting that he only ruled over the Mathura region. They do not follow traditional Indo-Scythian coinage patterns, but rather the designs of local rulers of Mathura, and are only made of lead and copper alloy. The legends only use the Indian Brahmi script, whether Saodasa's father Rajuvula had used coins derived from the Indo-Greeks, with legends in Greek and Kharoshthi. This suggests that Sodasa had significantly integrated into the localIndian culture. Sodasa's coins usually show on the obverse a standing female and tree-like symbol, with the legend"Mahakatapasa putasa Khatapasa Sodasa", i.e., "Satrap Sodasa, son of the Great Satrap". On the reverse appears a Lakshmi with elephants pouring water over her. Three types of legends are known, with one coin type of Sodasa bearing the legend "son of Rajuvula":
"Satrap Sodasa, son of the Great Satrap"
"Satrap Sodasa, son of Rajuvula"
"Great Satrap Sodasa"
Sculptural styles
The abundance of dedicatory inscriptions in the name of Sodasa, and the fact that Sodasa is known through his coinage as well as through his relations with other Indo-Scythian rulers whose dates are known, means that Sodasa functions as a historic marker to ascertain the sculptural styles at Mathura during his rule, in the first half of the 1st century CE. The next historial marker corresponds to the reign of Kanishka under the Kushans, whose reign began circa 127 CE. The Kankali Tila tablet of Sodasa is one of those sculptural works directly inscribed in the name of Sodasa. Another one is the Katra torana fragment. The sculptural styles at Mathura during the reign of Sodasa are quite distinctive, and significantly different from the style of the previous period circa 50 BCE, or the styles of the later period of the Kushan Empire in the 2nd century CE. Stylistically similar works can then be dated to the same period of the reign of Sodasa.
Early representation of the Buddha
The "Isapur Buddha" from Mathura, probably the earliest known representation of the Buddha, on a railing post, is dated to circa 15 CE under the reign of Sodasa. Another depiction of the Buddha from the same period apppears in the Bimaran casket.
Paleography
The inscriptions in the name of Sodasa are also an important marker for the paleography of the Brahmi script, the shape of the Brahmi letters having evolved in time, and also having varied depending on the regions.
