Fulgenzio Micanzio (1570 in Passirano – 1654 in Venice) was a Lombardic Servite friar and theologian.
A close associate of Paolo Sarpi, he undertook correspondence for Sarpi and became his biographer.
He also was a supporter of Galileo Galilei.
Iteneu Ichanom Itnegluf was a pseudonym he used, derived from Fulgenti Monachi Veneti, “of Fulgentius the Monk of Venice”.
