In the Catholic or Orthodox tradition, did Jesus appear to his mother after death? None of the Resurrection narratives seem to include Mary as a witness to the  resurrection or among the first few people who see Jesus after his death; not does she seem to be mentioned until Pentecost. Is there any subsequent Catholic or Orthodox  tradition that  Mary saw her Son after his resurrection  - or that she did not, perhaps with an explanation why?
The only reference that I am aware of is from St. Ignatius of Loyola’s Spiritual Exercises, written in 1524. (See also the Spanish original.)

In his meditation on the apparitions of the Lord after the Resurrection, he writes,


  Primero: apareció a la Virgen María, lo qual,
  aunque no se diga en la Escriptura, se tiene por dicho, en decir que aparesció a tantos otros; porque la Escriptura supone que tenemos entendimiento, como está escripto: (¿También vosotros estáis sin entendimiento?).
  
  First: he [Jesus] appeared to the Virgin Mary. Although the Scriptures do not say so explicitly, it is implied by the saying, “He appeared to many others” [a reference to 1 Corinthians 15:6]. The Scriptures presuppose that we have understanding, as in the saying, “Are you also without understanding?” [Matthew 15:16].


Hence, at least St. Ignatius of Loyola felt that it was obvious that Jesus appeared first to his mother.

There is nothing, however, in the Scriptures, nor in any of the writings of the Fathers, that indicates that for sure.
