Mentioned in the deed of gift of Georgios Kontostephanos Kalameas and his wife Eirene Kontostephanina Kapantritissa for the Monastery of Iberon from December 1309, in the act of the apographeus Manuel Manglabites for Ioannes Sguros Orestes from 1319/1320 or from 1304/1305 and in the chrysobull charter of the Byzantine Emperor Andronikos II Palaiologos for the pansebastos sebastos Ioannes Sguros Orestes from August 1323. He sold a place called Malesta near Melnik to Georgios Kontostephanos Kalameas (καὶ γὰρ τὸ σύνεγγυ̣ς τοῦ κάστρου Μελενίκου, τὸ ἐν τῆ τοποθεσία τῆς Μάλεστας, τὸν ἐξ αγορασίας μου τόπον ἀπὸ τοῦ Καρβουνάρη ἐκείνου). He also sold a field in the katepanikion Diakastron to Ioannes Sguros Orestes before 1319/1320 (Καὶ χωράφιον πλησίον ταύτης ἐξ ἀγορᾶς ἀπ̣ὸ̣ τοῦ Καρ̣βωνάρη ἐκ̣είνου μοδίων δ̣έκ̣α). He bought an 11 modioi vineyard with a nearby wasteland in Malesta from Mitas and sold it to Ioannes Sguros Orestes (Καὶ εἰς τὴν Μάλεσ̣τ̣αν ἀ̣μ̣πέλιον ἐξ ἀγορᾶς ἀπὸ τ̣ο̣ῦ̣ δηλωθέντο̣ς Καρβωνά̣ρ̣η̣ παρὰ τοῦ ε̣ἰ̣ρ̣ημένου Μιτᾶ ἐκείνου μοδίων ἕνδεκα, καὶ χέρσον μερικὸν συμπαρακ̣είμ̣εν̣ον). He sold a part from a 100 modioi field to Ioannes Sguros Orestes (καὶ χωράφιον ἐξ ἀγορασίας ὡσαύτως ἀπὸ τοῦ Καρβωνάρη καὶ τοῦ Λιτοβόη ἐκείνου καὶ ἀπὸ ἑτέρων ὡσεὶ μοδίων ἑκατόν). He vended also a vineyard in Malesta to Ioannes Sguros Orestes, where a 20 modioi vineyard was set out by the latter (Ἔτι δὲ καὶ ἀμπέλιον εἰς τὴν Μάλεσταν ἐξ ἀγορασίας ἀπὸ τοῦ δηλωθέντος Καρβωνάρη, ἐν ὧ κατεφυτεύθη παρ’ αὐτοῦ καὶ ἕτερον ἀμπέλιον μοδίων εἴκοσι, σὺν τῆ ἐκεῖσε εὑρισκομένη χερσαία γῆ).
