Fausta, or Flavia Maxima Fausta to call her by her full name, was the daughter of one western emperor, Maximianus Herculius (286–305), the sister of another, Maxentius (306–12), and the wife of a third, Constantine I (306–37). She was married to Constantine in 307, and bore him at least five children from 316 onwards, three sons (Constantine, Constantius, and Constans), and two daughters (Constantina and Helena).2 Following his defeat of his rival Licinius at the battle of Chrysopolis in 324, and the unification of the empire under his rule as the sole Augustus once more, Constantine honoured with the title of Augusta both his wife Fausta and his mother Helena, as is revealed by the issue of coins in their names each with this title.3 However, tragedy struck in 326 when Constantine appears to have executed first his eldest son Crispus, then Fausta herself. The reason for these executions, and the extent to which these deaths were related, has attracted a great deal of debate. Yet more remains to be said about the manner in which Fausta died, which may well provide an important clue as to the full circumstances of her death, whether she was executed, died by accident, or committed suicide even. Thus, it is my intention here, firstly, to offer a new explanation for the manner of her death, and secondly, to draw attention to an overlooked allusion to her death in a late Latin source, the Historia Augusta.
