"...the development of Sarasvati from her riverine origins is depicted in the earliest textual source on the goddess, the Rig Veda composed sometime after 1750 BC, through to her establishment as the deity of all forms of knowledge in epic and early Puranic sources (upto the seventh century C.E), as well as in the oldest surviving Hindu, Jain and Buddhist images (third to seventh century), to the Goddesses’s depiction in the most significant Buddhist source on Sarasvati, the Sutra of Golden Light, whose earliest extant redaction is from the beginning of the fifth century."
