A miraculously detailed work of history and philology--the myth of Isis is a source of endless interest for me, particularly as a reader of Apuleius. Witt's scholarship is resoundingly thorough here, as he surveys the deep syncretism of Isis and Osiris. From its obscure origins in Ancient Egypt to its bizarre and heterogeneous practices in Rome, the cult of Isis continues to plague scholars of German Romanticism, as well as early Greco-Roman literature. Witt's text remains among the best in the field.
