Judging by the place of this passus in Gregory's narrative, Ragnimodus died in 591.
Faramodus should almost certainly be identified with referendarius Faramodus, addressee of Venantius Fortunatus' carmen IX.12, composed ca 576. Hence, Faramodus must have been a referendary to King Chilperic (d. 584).
The episcopal catalogue of the bishops of Paris includes the name of Faramodus between Eusebius and Simplicius (who was elected bishop at an unknown date, but was certainly bishop by 601). See, Duchesne, Fastes épiscopaux de l'ancienne Gaule, vol. II, p. 468.
