The assertion that Vyasa is the incarnation of God (1.3.40) and the story of Yashoda seeing the universal form in the mouth of boy-Krishna (10.8.37-39) are specific to the Srimad Bhagavatam (e.g. not in the VIshnu Purana or Bhagavad Gita). As Abhinavaupta died in 1016 C.E., his devotional poem referencing the Bhagavata Purana would have been composed by that year at the very latest. Significantly, this proves Vopadeva (ca. 1350) could not be the author of the Bhagavata as it was referenced around three hundred years before he was born.
