This evidences three significant facts. First, Vopadeva (ca. 1350) - again - could not be the author of the Bhagavatam as it was listed by Al-Biruni (973-1050) around three hundred years before Vopadeva was born. Second, Al-Biruni stated the Bhagavatam was listed in the Vishnu Purana. And third, although Al-Biruni cited the Vishnu Purana and Bhagavad Gita extensively, he did not cite or quote the Bhagavatam (i.e. only listed it by name).
