Augustine of Hippo — as excerpted in the Catena Aurea on Matthew 20:29-34

“(de Cons. Ev. ii. 65.) Mark relates this miracle, but speaks of only one blind man. This difficulty is thus explained; of the two blind men whom Matthew has introduced, one was well known in that city, as appears by Mark’s mentioning both his name, and that of his father. (Mark 10:46.) Bartimæus the son of Timæus was well known as having sunk from great affluence, and now sitting not only blind, but a beggar. For this reason then it is that Mark chose to mention him alone, because the restoration of his sight procured fame to the miracle, in proportion to the notoriety of the fact of his blindness. Though what Luke relates was done after the same manner, yet his account is to be taken of another though similar miracle. (Luke 18:35.) That which he gives was done as they drew near to Jericho; this in the other two as they came out of Jericho. And the multitude rebuked them that they should hold their peace.”
