Their relics later suffered various vicissitudes: some were transferred to the churches of Sant'Adriano al Foro and Santa Prassede, in Rome, and part of these relics were sent to Eginhard, biographer of Charlemagne, who lodged them in the monastery of Seligenstadt.
According to Eginhard's brief description, the commendatio made to Pippin the Younger in 757 by Tassillo, Duke of Bavaria, involved the relics of Saints Denis, Rusticus, and Éleuthère, Saint Martin, and Saint Germain, which had apparently been assembled at Compiègne for the event.
