Augustine of Hippo — as excerpted in the Catena Aurea on Mark 16:9-13

“(ubi sup.) Luke relates the whole story respecting these two, one of whom was Cleophas, but Mark here touches but slightly upon it. That village of which Luke speaks may without absurdity be supposed to be what is here called a farm house, and indeed in some Greek manuscripts it is called the country. But by this name are understood not only villages, but also boroughs and country towns, because they are without the city, which is the head and mother of all the rest. That which Mark expresses by the Lord’s appearance in another form, is what Luke means by saying that their eyes were holden that they could not know him. For something was upon their eyes, which was allowed to remain there, until the breaking of bread.”
