Why did Jesus first reveal himself to women after the resurrection?

Mary Astell (an early 18th century feminist) notes one interpretation told to her:

in Some Reflections on Marriage.  Astell also notes the parallel fashion of God’s statement that the husband will rule the wife (to Eve) and that the younger will serve the older (by Isaac).  She argues that they were telling what would happen, not what ought to happen.
