He is the author of four poems: *Ascension*, *The Legend of St. Juliana*, *The Elene* (in fifteen cantos), and *The Fates of the Apostles*, which are contained in the Exeter and Vercelli codices.
The most significant of these is *Ascension*: placed in the manuscript between two other poems, *Nativitæ* and *Day of Judgement*, attributed to C., it forms with them the *Christ* cycle, pervaded throughout by trust in divine justice and goodness. Original in its conception is the final section: angels and saints gather on Mount Sion and Christ appears to them in a flame of light, while the universe is consumed in flames; then, with its roots in the mountain and its peak in the heavens, a great cross rises up, tinged with the blood of the King, yet so radiant that all the shadows of the cosmos are drowned in red glows.
