Augustine of Hippo — as excerpted in the Catena Aurea on Luke 24:13-24

“(ut sup.) But since Luke has said that Peter ran to the sepulchre, and has himself related the words of Cleophas, that some of them went to the sepulchre, he is understood to confirm the testimony of John, that two went to the sepulchre. He first mentioned Peter only, because to him first Mary had related the news.”
