His works include a comic mock epic, a panegyric to Charlemagne, epigrams of advice to young scholars, and a poetic overview of the seven liberal arts.
The anonymous exile's most famous work is a fragmentary Latin eclogue praising Charlemagne for his defeat of Tassilo III of Bavaria in 787.
The poem, Ad Karolum Regem ("To King Charles") in the Monumenta Germaniae Historica and In Praise of Poetry in Peter Godman's excerpted English translation, is written as a dialogue between poet and Muse (the parts of which are difficult for modern editors to perfectly discern), an idea picked up by Walahfrid Strabo.
The poet also affirms that secular subjects are equally worthy as sacred ones for versification, making the Ad Karolum Regum one of the earliest Latin Christian defences of courtly/public panegyric.
Ardenti ut sonipes carpit celer aequora cursu, Sic volat, heu, iuvenis non remanente gradu.
Dum faciles animi vobis sint forte, sodales, Discere ne pigeat scita superna dei.
His metrical poem on the seven liberal arts devotes twelve lines to each of the branches, grammar, rhetoric, dialectic, etc., showing the origin, scope, and utility of each in succession.
