[282] Monumenti delle Arti Cristiane Primitive nella Metropoli del Cristianesimo. Roma, 1844. The political troubles of the year 1848 prevented its completion. The theological zeal of this writer, however, has in many cases biassed his judgment. “In every page of his work,” says a critic in the Edinburgh Review, (January, 1859, Am. ed. ccxxi, p. 48,) “an exuberant desire to find evidence in support of the later Romish doctrine among these records of the primitive church predominates over every other consideration.”

Several of the illustrations are from the same sources.
