Though Hippolytus is very severe on Callistus, he speaks of Marcia, the concubine of Commodus, as “a God-loving concubine.”[271] He states that Callistus was a slave, and if this were the case the bishop’s own experiences would be a strong stimulus to his action.[272] BIBLIOGRAPHY. This is not a bibliography in the strict sense of the term. It does not aim at completeness. It is a list of the works specially relating to the subject of the book which have been used during its composition and revisal, and it includes only those treatises in which some contribution is made towards the elucidation of important points. I have omitted a considerable number of programmes which seem to me in no way to advance our knowledge. I have also omitted a large number of text-books, and of books such as Becker’s ‘Charicles,’ and ‘Gallus,’ and ‘The Life of the Greeks and Romans,’ by Guhl and Koner. There is a large number of books that deal with the history of woman in general, such as those of Alexander and Lord Kames. I have placed Mr. Lecky’s book in my list because it mentions most of the works of this class. There are also numerous books treating of the history of marriage. Mr. Howard’s able and comprehensive work has a full bibliography on this subject. Those who are interested in Sappho will find a list of books in Wharton’s edition, though, of course, he does not include the latest collections of the Greek lyric poets, such as those of Farnell and Smith. The revelations made in the papyri of Egypt well deserve the attention of scholars. An enumeration of the marriage contracts contained in the papyri is to be found in ‘Nietzold,’ p. 26. Messrs. Grenfell and Hunt have admirably discussed the questions that arise out of the matrimonial documents. The tables of contents and the indexes in their edition of the papyri make them accessible to the scholar without trouble. Achelis, N.--Virgines subintroductae. Ein Beitrag zum VII Kapitel des I.
