The Byzantine Emperor Andronikos II Palaiologos confirmed in June 1309 the possession of the Monastery of Saint John Prodromos on Mount Menoikeus near Serres over the Metochion Hagios Demetrios tu Krilatu in the plot Platanai in the vicinity of the town Melnik (καὶ ἕτερον εὐκτήριον οἶκον περὶ τὸν Μελένικον ἐν τῆ τοποθεσία τῶν Πλατανῶν διακείμενον καὶ εἰς ὄνομα τιμώμενον τοῦ ἁγίου μεγαλομάρτυρος Δημητρίου καὶ ἐπικεκλημένον τοῦ Κριλάτου). The Byzantine Emperor Andronikos II handed over to the Monastery of Hilandar the summer pasture called Matzista and the Metochion Hagios Demetrios tou Krilatou/Pteratou (Ὡσαύτως ἔχει θέλημα καὶ διορίζεται ἡ βασιλεία μου, ἵνα κατέχηται παρὰ τῆς δηλωθείσης σεβασμίας μονῆς τοῦ Χελανταρίου καὶ ἡ περὶ τὸν Μελενίκον δημοσιακὴ πλανηνὴ ἡ Μάτζιστα σὺν τῆ τοῦ Ἁγίου Δημητρίου τοῦ Πτερωτοῦ καλουμένη). The Byzantine Co-Emperors Michael IX. Palaiologos and Andronikos III Palaiologos confirmed the owner right of the Monastery of Hilandar over the summer pasture Matzista and the Metochion Hagios Demetrios tou Krilatou/Pteratou (καὶ ἡ περὶ τὸν Μελενίκον δημοσιακὴ πλανηνὴ ἡ Μάτζιστα σὺν τῆ τοῦ Ἁγίου Δημητρίου τοῦ Πτερωτοῦ καλουμένη). Probably identical with the Monastery Ajo Demetri mentioned in the Defter for the Sanjak Küstendil in the 16th century.
