Mucalinda first appears in the
Mucalinda Sutta, where it is described that the naga king protected Buddha from the elements by encircling Buddha's body seven times with his coils and standing with his hood spread over. After Buddha finished meditating and the sky cleared, Mucalinda adopted the form of a youth and bowed before him. The first existent artwork depicting Mucalinda comes from a 2nd-century BC
stupa in
Pauni,
Maharashtra, where the naga is portrayed as having five heads and guarding Buddha's empty seat. Contemporaneous artwork from
Sanchi has him portrayed in zoo-anthropomorphic form and attended by a retinue of nagini. ==Mahayana==
