Subsequently he was banished from Pippin's court on a charge of inciting Pippin against his father, and retired to Strassburg, where he sought to regain the emperor's favour by writing a poem on his life and deeds. About 830 he obtained his recall, and has been identified with Hermoldus, who appears as Pippin's chancellor in 838.
Ermoldus was a cultured man with a knowledge of the Latin poets, and his poem, In honorem Hludovici imperatoris ("In honour of Emperor Louis"), has some historical value. It consists of four books and deals with the life and exploits of Louis from 781 to 826. He also wrote two poems in imitation of Ovid, which were addressed to Pippin.
His Carmina in honorem Hludovici, edited by Edelestand Dümmler, and other writings are published in the Monumenta Germaniae historica. Scriptores, vol. 2 (Hanover, 1826 fol.); by J.P Migne in the Patrologia Latina, tvol. 105 (Paris, 1844); and by Ernst Dümmler in the Poetae Latini aevi Carolini, vol. 2 (Berlin, 1881–1884).
