He died as monk Ioakeim on 6 February (Ὡσαύτως ποιήσετε μνημόσυνα καθ’ ἑκάστην τοῦ χρόνου περίοδον τὴν ἕκτην τοῦ φευρουαρίου μηνὸς καὶ ὑπὲρ τοῦ μακαρίου κτήτορος ὑμῶν τοῦ μεγάλου στρατοπεδάρχου Ἀγγέλου Δούκα τοῦ Συναδηνοῦ κυροῦ Ἰωάννου, τοῦ διὰ τοῦ θείου καὶ ἀγγελικοῦ σχήματος μετονομασθέντος Ἰωακεὶμ μοναχοῦ). He was a κῦρ. He was toparch of Polog before 1275/1276 (ὁ δέ γε πατὴρ τοῦ πρὸς ἑσπέραν κατὰ τὴν Δαλματίαν λεγομένου Πολόγου τοπάρχης ἦν) and Megas stratopedarches from 1275/1276 to 1283/1284.
