Acami Giacomo, an Italian count of the last century, was the author of several works, among them Dell' Antiquita, Autore, e Pregi del Sagramentario ῥVeronese (Rome, 1748, 4to). It is an apologetical dissertation in three parts. Part first is designed to show that this sacramentary was composed in the first ages of the Church. The following facts are cited in proof, viz. the extracts from Holy Scripture contained in it are taken from the Old Italic version, and not the Vulgate; that at the time when it was composed it was the custom to make use at the sacrifice of the mass of the bread and wine offered by the fideles; that the subdiaconate was not one of the holy orders; and that the feast of the accession of Peter to the episcopal chair of Rome was still celebrated April 25. In part second he endeavors to prove that St. Leo was the compiler of the sacramentary. In part third he infers from certain prayers used in the book a belief in the dogmas attacked by the heretics of the 14th, 15th, and 16th centuries. A reply to this work by an Anabaptist in London elicited from the count a rejoinder, Jacobi, Comitis Acami, de Pcedobaptisno, etc., sive de Perpetuo Ecclesice Rituac Doyguae 'laptisandorum, etc. (Rome, 1755).
