The small and humble church of Agios Athanassios, also called "The Glebe of Aegina", was testified to belong to the Monastery of the Assumption of the Virgin (“Παναγίας Χρυσολεοντίσσης”) of the island of Aegina. It was built during the Turkish occupation of Athens.
The oldest frescoes date back to the 1638. Newer renovations since the early 20th c. have totally disformed the western side, while part of the rest of the church now lies in a car service shop.
Saint Athanassios of Alexandria (c. 296–298 – 2 May 373), also called Athanassios the Great, or Athanassios the Confessor was the twentieth bishop of Alexandria (as Athanassios I).
His episcopate lasted 45 years of which over 17 were spent in five exiles ordered by four different Roman emperors. Athanassios was a Christian theologian, the chief defender of Trinitarianism against Arianism, and a noted Egyptian leader of the fourth century.
Within a few years after his death, Gregory of Nazianzus called him the "Pillar of the Church". His writings were well regarded by all Church fathers who followed, in both the West and the East, who noted their rich devotion to the Word-become-man, great pastoral concern, and profound interest in monasticism. In the Orthodox Church, Athanassios he is considered as the "Father of Orthodoxy". Some Protestants label him as "Father of the Canon". Athanassios is venerated as a saint, whose feast day is on January 18th in the Orthodox Church.
