Hippolytus composed his now largely lost work of the history of the Roman Empire sometime in the late 6th century. While its influence appears to resonant across the centuries, the text itself has been lost. What is compiled here is the few surviving fragments of his works preserved in various extended quotations by other authors. Much of his surviving writings give us precious insight in the personal life of the family of Christ, his sisters, and extended family, as well as notes about the reign of the Emperor Constantine I.
