Il finança l’ouverture d’écoles, dans son village natal et dans d'autres locatités de l’Epire. En 1860, il participa à ce débat sur la littérarisation de la langue albanaise, qui se déroulait non seulement dans le journal de Pykaios, mais aussi dans l’Elpis, un périodique de la capital grecque. Dans une lettre adressée à ce journal, il estimait que la langue albanaise n’etait pas en mesure de devenir une langue littéraire, mais qu’elle ne devait pas être abandonnée. Il suggérait l’usage de l’alphabet, à base grecque, employeé dans l'ecole de Labovë fondée par ses soins."

"Whereas Libohovë and the villages north of it are Albanian in speech, those of the plateau form the most easterly pocket of Greek speech in North Epirus. Between Libohovë and the plateau the two hamlets of Labovë (115 houses) are of mixed speech, the mother tongue being Albanian."
