Synthesises early Irish sources on fighill / figel / crosfigell, describing it as a form of prayer “performed kneeling or prostrate on the ground, with the hands extended in the form of the cross,” and emphasising its role as a physically demanding vigil that disciplines body and mind:

Uses Gwynn & Purton’s material to describe Irish monks (including Mael Ruain) performing cross-vigils, “chanting prayers while stretching their arms out rigidly in the form of a cross,” highlighting this posture as a known monastic practice:

Edits and translates the early Irish penitential De arreis (“Of Commutations”), which contains multiple penances involving cross-vigils with the Beati, genuflexions, and blows; includes phrases like “seven Beati in cross-vigil” and “Beati immaculati in cross-vigil without lowering the arms”:

Explains figel / crosfigell as either a time of vigil or a characteristic bodily posture, often linked with reciting Psaumes 118/119 and other psalms “without lowering the arms,” and analyses its role within Céli Dé penitential practice:
