His earliest work appears to be his Vita Sanctae Brigidae, a Latin hagiography of the Irish Gaelic saint Brigid of Kildare.Rigg, History of Anglo-Latin Literature, p. 54 The story, Lawrence tells us, was that Lawrence had received from Ailred's father a hagiography of the saint written in a "half-barbaric" [semibarbarum] style. Lawrence polished it up, and sent it to Ailred while the latter was a member of the court of David I, King of the Scots; that is, between 1130 and 1134.Rigg, History of Anglo-Latin Literature, p. 54; Sharpe, Medieval Irish Saints Lives, p. 33, n. 121 Lawrence's letter to Ailred survives.For which, see "Survey of the Unedited Work of Laurence of Durham", pp. 249–265; see also Sharpe, Medieval Irish Saints Lives, p. 33, n. 121
