The opening as it read in 2025

Brontochion Monastery ( Greek : Βροντόχιον, Μονή Βροντοχίου ) is a monastery in Mystras , Greece. The abbot Pachomius incorporated into it the small church of the Hodegetria , or "Aphentikon", as the monastery's catholicon . The church was reconstructed and completed around 1310, with some scholars giving 1308-1312 as the construction dates and others 1310–1322. The despot Theodore I Palaiologos , who died in 1407, is buried here. The Hodegetria Church is the first example of what's called the "Mystras type" design. The lower floor is a three-aisled basilica, whereas above is a traditional Byzantine cross-in-square church plan. The cross-in-square, five-domed gallery is encircled by a portico that has a belfry . There are also features more typical of Constantinople , such as the use of blind arches. On the lower level the walls are covered by marble revetment, a luxurious feature, and there is also a surviving fresco of the Virgin Mary as Zoodochos Pege (Life-containing Source) in the lunette above the so-called royal door. During Ottoman rule , the monastery was converted into a mosque. Collier's encyclopedia: with bibliography and index . Hellenic Ministry of Culture . The Oxford Handbook of Byzantine Studies .
