<P> Vāsishka was a Kushan emperor who seems to have had a 20 - year reign following Kanishka . His rule is recorded as far south as Sanchi (near Vidisa), where several inscriptions in his name have been found, dated to the year 22 (the Sanchi inscription of "Vaksushana"--i.e., Vasishka Kushana) and year 28 (the Sanchi inscription of Vasaska--i.e., Vasishka) of the Kanishka era . </P> <P> Huvishka (Kushan: Οοηϸκι, "Ooishki") was a Kushan emperor from about 20 years after the death of Kanishka (assumed on the best evidence available to be in 140) until the succession of Vasudeva I about thirty years later . His rule was a period of retrenchment and consolidation for the Empire . In particular he devoted time and effort early in his reign to the exertion of greater control over the city of Mathura . </P> <P> Vasudeva I (Kushan: Βαζοδηο "Bazodeo", Chinese: 波 調 "Bodiao") was the last of the "Great Kushans ." Named inscriptions dating from year 64 to 98 of Kanishka's era suggest his reign extended from at least 191 to 225 AD . He was the last great Kushan emperor, and the end of his rule coincides with the invasion of the Sasanians as far as northwestern India, and the establishment of the Indo - Sasanians or Kushanshahs in what is nowadays Afghanistan, Pakistan and northwestern India from around 240 AD . </P> <P> The Kushan religious pantheon is extremely varied, as revealed by their coins that were made in gold, silver, and copper . These coins contained more than thirty different gods, belonging mainly to their own Iranic, Greek, and Indo - Aryan worlds as well . Kushan coins had images of Kushan Kings, Buddha, and figures from the Indo - Aryan and Iranian pantheons . Greek deities, with Greek names are represented on early coins . During Kanishka's reign, the language of the coinage changes to Bactrian (though it remained in Greek script for all kings). After Huvishka, only two divinities appear on the coins: Ardoxsho and Oesho (see details below). </P>
