HARTMANNUS of SAN GALLO. - Benedictine, master at the abbey of St Gall, of which he became abbot in 1924. He was a pupil of Notker Balbulus and is mentioned in the chronicle *Casus S. Galli* by Ekkehard IV, who calls him “praeter sapientiae doctrinalem doctorem religionis tenacissimus” (MGH, *Scriptores*, II, p. 102, 5).
About fifteen of his ecclesiastical hymns survive, in various metres and in Latin, including a fine poem in honour of Christ in Sapphic strophes. Short verses also greet the arrival at St Gall of the kings Conrad and Charles III.
A namesake of his was a monk of the same abbey who, towards the end of the 10th century or early in the 11th, following the example of Ekkehard I, likewise wrote in Latin a life of St Wiborada, a nun who had suffered martyrdom near St Gall during a Hungarian invasion in 925. This composition is judged by Conrad of Fabaria, continuator of the *Casus S. Galli*, to be “luculento satis sermone” (MGH, *Scriptores*, II, p. 166). To it may be added an epitaph in honour of the saint, perhaps later in date.
