The ancient veena is an early Indian arched harp, not to be confused with the modern Indian veena which is a type of lute or stick zither. Names of specific forms of the arched harp include the chitra vīṇā with seven strings, the vipanchi vīṇā with nine strings and the mattakokila vīṇā a harp or possibly board zither with 21 strings.[1][2]
The instrument is attested on a gold coin of the Gupta Empire from the mid-300s CE.[3][4][5] The instrument was also illustrated in the oldest known Saraswati-like relief carvings, from Buddhist archaeological sites dated to 200 BCE, where she holds a harp-style veena.[6]
