The Byzantine Emperor Andronikos II Palaiologos donated the pasture Lakteba in Lestia near Melnik in September 1327 (ἔτι δὲ καὶ τὴν περὶ τὸν Μελενίκον εἰς τὰ Λέστια δημοσιακὴν πλανηνὴν τὴν Λάκτεβαν). The monks of the Zographou Monastery on Mount Athos requested the Byzantine Emperor Andronikos III Palaiologos to allow them an exchange of property. The Byzantine Emperor Andronikos III granted the monks the summer pasture Tzerkbistan near Melnik in March 1328 and confirmed that they will use it instead of the property Laktebas in Lestia near Melnik (Καὶ ἀντὶ τῆς κατεχομένης παρ᾿αὐτῶν τῶν μοναχῶν διὰ τῶν δηλωθέντων χρυσοβούλλων περὶ τὸν Μελενίκον δημοσιακῆς πλανηνῆς τῆς οὕτως καλουμένης Λάκτεβας, ἐπιλάβηται καὶ κατέχη τὸ μέρος αὐτῶν, τὴν περὶ τὸν αὐτὸν τόπον τοῦ Μελενίκου, δημοσιακὴν ἑτέραν πλανηνὴν τὴν λεγομένην, Τζέρκβισταν, ἡ βασιλεία μου τὴν ζήτησιν καὶ παράκλησιν τῶν εἰρημένων μοναχῶν προσδεξαμένη). The forged chrysobull charter of the Byzantine Emperor Ioannes V Palaiologos, which is dated in the text to January 1342, but was produced between the year 1357 and 1372, confirmed the possesion of Tzerkbistan near Melnik by the Zographou Monastery (καὶ ἀντὶ τῆς πλανηνῆς τῆς λεγομένης Λάκτεβας τῆς κατεχομένης παρὰ τῶν δηλωθέντων μοναχῶν, ἐπιλαβέσθαι καὶ κατέχειν τὸν τόπον αὐτῶν, τὴν περὶ τόπον τοῦ Μεληνίκου δημοσιακὴν ἑτέραν πλανηνὴν τὴν λεγομένην Τζέρκβησταν).
