April 1st or maybe April 2, depending on who you ask, is the feast day of the (possibly) sixth century St. Mary of Egypt.
I say “feast” loosely, as there does not seem to be any food associated with this occasion.
Briefly, this saint led a life of lust in Egypt, then traveled to Jerusalem, became a saint, and spent the rest of her life in the desert, where she met Saint Zosimas of Palestine. She was able to levitate, and walked on water to cross a river. They spent a great deal of their conversation arguing about who was going to bless who. St Mary finally blessed Zosimas.
As far as the scholarship, you can read the thing here. There was a huge urban legend thing going on about female saints who went into the desert with very little food after giving up a life of lust in their late 30s. https://staging.doaks.org/research/publications/doaks-online-publications/holy-women-of-byzantium/talbch3.pdf
There are some frescos associated with her, Panagia Asinou Church, Cyprus, maybe 12th century. I don’t see her in the frescoes, but whatever, they are very impressive.
There is some orthodox tradition of the usual Troparion & Kontakion, but good luck finding any recordings.
