His father kaisar Nobakos sponsored the renovation and decoration of the Virgin Maryʼs Church in Mali Grad in the year 1368–1369 (Άνηγέρθη ἐκ βάθρου καὶ κόπού καὶ μόχθοῦ ὁ θεϊος κὲ πάνσεπτος ναώς ουτος της υπεραγίας δεσπίνης ἡμων Θεοτόκου καὶ ἀνηστορίθην παρὰ του αὐφθέντου αὐτοῦ πὰνευτυχεστάτου κέσαρος Νοβάκου ἠγουμενέβῶντὸς δὲ Ἰωνὰ μοναχοῦ. Αὐφθεντεύβοντος πανυψηλοτάτου κραλήου τοῦ Βεληκασίνου. Άρχαηερατεύωντος δὲ τῆς ἀγιωτάτης ἀρχιεπησκοπῆς τῆς Πρότης Ἰουστινηανης, ετους ͵ςωοζʹ). The family portrait of Nobakos has been preserved on the western external façade. He and his sister are painted to the left of the virgin, who is the central figure of the ktitorial composition.
