Until the 4th century CE, the worship of Vāsudeva-Krishna seems to have been much more important than that of Vishnu. With the Gupta period, statues focusing on the worship of Vishnu start to appear, in the form of an evolution based on the earlier statues of Vāsudeva-Krishna. Many of the statues of Vishnu appearing from the 4th century CE, such as the Vishnu Caturanana (Four-Armed), use the attributes and the iconography of Vāsudeva-Krishna, but add an aureole starting at the shoulders.
