Among the oldest structures of the Monastery is the chapel of St Georgios the Trophybearer, which is located on the north side of the monastic complex. The chronology (1431) which exists in the inscription in the chapel had been falsified in the 19th century by Konstantinos Simonidis, who changed the original date of 1554. Its frescoes have been reliably dated to 1552/55, and are attributed to the artist Antonios, who is also known from a 1544 inscription which has survived in the arch of the altar of the old cathedral of the Xenofontos Monastery. The frescoes of Antonios are characterized by an ‘anti-classical’ tendency, while in individual sections, elements of Cretan painting or even of his almost contemporary, the Theban painter Frangkos Katelanos, can be observed. Among the important icons in the chapel are the 16th century icons of Christ Enthroned, flanked by St Georgios and St Pavlos of Xeropotamos, and the icon of the Virgin Mary of Pammakaristos (Παναγίας Παμμακαρίστου), which name is obviously is derived from the similarly-named Byzantine pilgrimage church in Konstantinople. In the same period, at about the middle of the 16th century, the large epistyle of the icon screen of the chapel was installed, with a depiction of the Great Prayer (Μεγάλη Δέηση) following the prototype of the Cretan school. Finally, the altar door of the icon screen is of particular interest, with its representation of the Annunciation (early 16th century) and its large despotic icons of Christ, the Ruler of All and the Virgin Mary.
