The Works of Hippolytus

At that time Hippolytus, among very many other writings, composed his treatise On the Passover. In it he sets out a register of dates and proposes a sixteen-year cycle for finding the Passover, bringing his dates down to the first year of the emperor Alexander. [a] Of his other writings, these have come down to us: On the Six Days of Creation, On What Follows the Six Days, Against Marcion, On the Song, On Parts of Ezekiel, On the Passover, and Against All the Heresies. You could find a great many others preserved among many people. [b]
