According to the Vita of Saint Nicodemus written by the Patriarch of Constantinople Philotheos Kokkinos he was a Serb. But his name does not sound like a Serbian anthroponym in any way. Either Karabides himself derived the Greek variant from the word καραβίς, which means ship, and adopted it as his name, or Kokkinos simply translated his original Serbian epithet, which actually expressed his professional activity, into Greek in order to make it more accessible to the public. Mentioned in the charter from 28 June 1336, which has been preserved in the archives of the town Dubrovnik and in the Life of Saint Nicodemus written by the Patriarch of Constantinople Philotheos Kokkinos. His son-in-law was Ioannes Liberos (Oliuer Gherchinich, baro domini Regis Raxie et gener Charauide). He came to Thessalonike from Dalmatia according to the Vita of Saint Nicodemus. Philotheos Kokkinos designates him as a deserter. He was afflicted by a terrible paralysis. He spent almos all of his fortune on doctors. Finally he was healed at the shrine of the Saint Nicodemus sometimes after 1307 (Γεώργιός τις τὸ γένος Τριβαλλός, τὴν ἐπωνυμίαν Καραβίδης, ἐκ Δαλματίας ὁρμώμενος, ἧκέ ποτε Ῥωμαίοις αὐτόμολος· οὗτος εἶχε τὰς διατριβὰς κατὰ Θεσσαλονίκην. Καί ποτε τούτῳ πάρεσις δεινὴ μάλα ἐπισκήπτει, ἣν ἄρα καὶ φύσις καὶ τέχνη ἰατρικὴ ἀπειρήκει, τὸ χαλεπὸν ταύτης, ὥσπερ οἶμαι, μυσαττομένη. Πολλὰ τοιγαροῦν καμὼν καὶ ἰατροῖς δήπου τὸν ἅπαντα βίον σχεδὸν ἀναλωκὼς οὐδὲν ἐκεῖθεν ἀπώνατο ἢ τὸ καταγνῶναι πάντως ἐκείνων. Ὀψὲ δὲ καὶ μόλις ἑαυτὸν ἀνενέγκας, ἔγνω δεῖν καὶ πρὸς τὸ τοῦ ἁγίου τοῦδε τέμενος καταφυγεῖν. Καὶ δὴ θᾶττον ἐκεῖσε γεγονὼς πολλὰ τὸν ἅγιον ἱκετεύει, ναὶ μὴν καὶ δάκρυσι, τὸ ἀνυσιμώτατον εἰς πειθὼ φάρμακον, κατὰ τῆς ἱερᾶς τοῦ ἁγίου ἐκχέει σοροῦ, καὶ τηνικαῦτα τοῦ πάθους μὲν εὐθὺς ἀπαλλάσσεται, τῷ ἰδίῳ δὲ οἴκῳ ὑγιὴς χαίρων ἐπάνεισιν). Georgios Karabides gave in pawn a silver belt, silver drawer and 195 ducats in gold to Junije Lukarević. Ioannes Liberos, the son-in-law of Georgios Karabides, stated on 28th June 1336 in the presence of Nikola Falletro, the comes of the town of Ragusa, that he received the former treasury of Karabides from Junije Lukarević. Liberos swore that he will give the treasury to the Serbian King Stefan Uroš IV Dušan and request a charter for Junije Lukarević from the king, which will confirm the receipt of treasury and ruled out the possibility of demand by the king, Liberos or the children of Karabides (Oliuer Gherchinich, baro domini Regis Raxie et gener Charauide, constitutes ante presentiam nobilis et potentis viri domini Nicolai Falletro, honorabilis comitis Ragusii, contentus e confessus fuit habuisse et recepisse et apud se habere a Junio de Lucarom de Ragusio unam centuram de argento et unam ladicam de argento, ponderis inter ambas librarum tredecim et unciarum V, et centum nonaginta quinque ducatos de auro, que centura et ladica et ducati acomandati fuerunt per dictum Carauidam, socerum olim dicti Oliueri, eidem Junio, ut idem Junius confessus fuit. Et similiter idem Oliverius confessus fuit tantas fuisse res et ducatos, accomandatas eidem Junio per dictum Charauidam et non plures, cum infrascriptis pactis et condictionibus, uidelicet quod ipse Oliuerius teneatur et debeat predictam centuram et ladicam et ducatos dare in manibus domini Regis Raxie in presentia Petri de Ribica et Marini filii Junii de Uolcasso de Ragusio et fieri facere ab ipso Rege eidem Junio de Lucaro unam apouiliam, sigillatam suo sigillo, continentem, qualiter ipse dominus Rex uel suus successor nec frater, filii seu filia dicti Charauidi seu aliqua alia persona de dicta centura et ladica et ducatis non possint facere uel mouere aliquam litem uel questionem in regno Raxie et Slauonie seu in aliquo loco, in curia uel extra, eidem Junio). According to the later historian Mauro Orbini a certain Karabides Fratnut with Đuraš Ilijić were among the closest counsellors of the Serbian Young King Stefan Uroš Dušan. They were with the young king, when he planned to owerthrow the government of his father Stefan Uroš III Dečanski.
