He was the son of a cavalry officer of the Venetian army and in 1757 he was in Dalmatia probably following his father in his military duties (Dalmatia was at this time under Venetian rulers).
Practically nothing is known about the first twenty years of Lorgna. The general governor of Dalmatia, Alvise Contarini, knowing his abilities and versatility, appointed him as his secretary and interpreter. In 1762 he was enrolled in the Venetian army and went to Croatia for few time, because he was appointed professor of mathematics in the military academy for engineers in Castelvecchio in Verona.
Lorgna worked at the Military College of Castelvecchio in Verona for the rest of his career teaching courses on trigonometry, mechanics, statics for construction, ballistics and hydraulics.
He was never married. He died when the French army was occupying Verona.
Between his eighty works, can be stated the following as the most important:
