Originally published in 1912, this book consists of a large selection of ancient Christian inscriptions, mainly of Roman origin, together with an elementary treatise on the subject of Christian epigraphy. The text is particularly notable for being the creation of Orazio Marucchi (1852-1931), a prominent disciple of the great Italian archaeologist Giovanni Battista de Rossi (1822-1894). Inscriptions are organised into a wide variety of classes; explanations regarding their respective source are given beneath. Additionally, there are a number of images showing inscriptions in their original form. Chiefly written for young students of the time, this remains a fascinating book that will be of value to anyone with an interest in archaeology or early Christianity.
