The presbyter in question could be named Etherius or Herius, depending on how we read the text: "Etherio" or "et Herio". Sossius was a martyr of Misenum near Naples. Florus is probably identical with Bishop Florius of unknown place in Italy, deposed by Pope Zosimus for following Pelagius in AD 418 (Florus 4 in PCBE Italie 1). For this episode see COS E00997.
