Life and Asceticism
According to tradition, Zosimas was a Sinaite monk who came from or by way of Mount Sinai and headed a group of monks who settled in caves in the area of present-day Tuman, in the wooded hill country near Golubac in eastern Serbia. He devoted himself to extreme fasting and prayer in his rocky hermit's cave, living as a recluse until his death.
Serbian tradition links his death to the knight Miloš Obilić. As the legend relates, Obilić while hunting accidentally wounded the hermit and brought him to his court's healer; Zosimas refused treatment and asked to be left to die. In repentance, Obilić began to build a church at the site of the hermitage.
