The octagonal church of Hagioi Theodoroi, the first katholikon of the Brontochion Monastery, was founded, according to an inscription, by Daniel, who does not appear in any other source, and by Pachomios, who in 1296 is referred to as the monastery’s abbot. It is the latest in date of the surviving octagon churches represented by the monasteries of Daphni and and Hosios Loukas and was inspired perhaps by the Church of Hagia Sophia at Monemvasia. The few surviving sculptures date from the church’s construction and represent local artistry. Considerably more space is allotted to fresco decoration than is usually the case in the churches of this type: there is a feast cycle, a Passion cycle, and a Virgin cycle.
