[1] We know about Eigil primarily from the Latin Life (Vita Aegili) that the monk and teacher of Fulda, Candidus Bruun composed about him after his death.
In 811, monks from Fulda, possibly including Eigil, petitioned Emperor Charlemagne to remove the abbot.
Charlemagne's son and successor, Louis the Pious, banished Ratgar and sent two of his delegates, Aaron and Adalfrid, along with their associates to reform the abbey according to proper monastic discipline .
[2][6] In a poem,[7] his student and successor Hrabanus Maurus celebrated his clemency and gentleness, supporting Candidus' positive portrait.
[5] Eigil died in 822 and was succeeded by the head teacher of Fulda's school, Hrabanus Maurus,[5] one of his former pupils.
