Matranga was born in Piana degli Albanesi, the largest and most populous Arbëreshë colony in Sicily.

A writer of noble personality and a priest of the Byzantine rite, he is best known for the first ever creation in the Albanian language, in the Tosk dialect common in southern Albania and among Arbëreshë communities in Italy, of the Christian Doctrine (E Mbësuame e Krështerë) by Spanish Jesuit P. Ledesma.

The probable autograph, where Matranga's version is interspersed with the Italian text of Ledesma's work, is contained in Barb.

Matranga was the translator of a catechism book entitled E mbsuame e krështerë (Christian Doctrine) from Latin to medieval Albanian.

This book, E Mbësuame e Krështerë, has particular historical significance, linguistic and literary, being the oldest document in the toskë variant of Albanian literature.
