John Chrysostom — as excerpted in the Catena Aurea on John 20:10-18

“(Hom. l) But why, when she is talking to the Angels, and before she has heard any thing from them, does she turn back? It seems to me that while she was speaking, Christ appeared behind her, and that the Angels by their posture, look, and motion, shewed that they saw our Lord, and that thus it was that she turned back.”
