Greek Expositor (anonymous) — as excerpted in the Catena Aurea on Luke 7:36-50

“(Severus Antiochenus.) For since the four Evangelists relate that Christ was anointed with ointment by a woman, I think that there were three women, differing according to the quality of each, their mode of action, and the difference of times. John, for example, relates that Mary, the sister of Lazarus, six days before the Passover, anointed the feet of Jesus in her own house; but Matthew, after that the Lord had said, You know that after two days will be the Passover, adds, that in Bethany, at the house of Simon the leper, a woman poured ointment upon the head of our Lord, but did not anoint His feet as Mary. Mark also says the same as Matthew; but Luke gives the account not near the time of the Passover, but in the middle of the Gospel. Chrysostom explains it that there were two different women, one indeed who is described in John, another who is mentioned by the three.”
