Euthymius the Great was a 5th-century Armenian Christian abbot and hermit who lived in Palestine. Born in Melitene, he eventually moved to the Judaean desert, where he established several monastic settlements. While he preferred a solitary life following the Egyptian monastic tradition, he founded both communal monasteries and smaller lauras. He is noted for his theological stance, specifically supporting the decisions of the Council of Chalcedon in Jerusalem. He died in Jerusalem in 473 and is recognized as a saint in the Eastern Orthodox and Roman Catholic traditions.
