1. It may be well to add that in the sixth book of his exposition of the Gospel of John he states that he prepared the first five while in Alexandria. Of his work on the entire Gospel only twenty-two volumes have come down to us.
2. In the ninth of those on Genesis, of which there are twelve in all, he states that not only the preceding eight had been composed at Alexandria, but also those on the first twenty-five Psalms and on Lamentations. Of these last five volumes have reached us.
3. In them he mentions also his books On the Resurrection, of which there are two. He wrote also the books De Principiis before leaving Alexandria; and the discourses entitled Stromata, ten in number, he composed in the same city during the reign of Alexander, as the notes by his own hand preceding the volumes indicate.
