Feast Day Of Saint John Cassian - 28 February / 29 February

 Quoted below is from Britannica [1]:

St. John Cassian, Latin Johannes Cassianus, also called Johannes Eremita or Johannes Massiliensis, (born 360, the Dobruja, Scythia—died 435, Marseille; Eastern feast day February 29 (observed on February 28 during non-leap years); Western feast day July 23), ascetic, monk, theologian, and founder and first abbot of the famous abbey of Saint-Victor at Marseille. His writings, which have influenced all Western monasticism, themselves reflect much of the teaching of the hermits of Egypt, the Desert Fathers. Cassian’s theology stemmed from, and was subordinate to, his concept of monasticism. He became a leading exponent of, in its early phase, Semi-Pelagianism, a heresy that flourished in southern France during the 5th century.

Below are two of Saint John Cassian's writings on Prayer (see links below at [2] & [3]):
