Dominicus was the author of a Hebrew book entitled, "Ma'ayan Gannim" (Fountain of the Gardens), on the principles of the Christian faith. He also translated into Hebrew the whole of the New Testament, and most of the Apocryphal books (1615-17). He was the compiler of the "Sefer ha Zikuk" (Book of Expurgation), still in manuscript, one copy of which (in the library of Cardinal Berberini, Rome), shews revision by him as late as 1619.

He arranged the Masorah for the "Biblia Veneta," 1518, published by his disciple Bromberg.
