Augustine of Hippo — as excerpted in the Catena Aurea on Luke 8:26-39

“(de Con. Ev. l. ii. 24.) The words of Mark, that there was a herd of swine nigh unto the mountains, and of Luke, on the mountains, do not differ from one another. For the herd of swine was so large, that they might be part on the mountain, part near it. For there were two thousand swine, as Mark has stated. (Mark 5:13.)”
