Archard was a monk of Citeaux, and master of the novices at Clairvaux, in the time of St. Bernard, who composed a Life of St. Geselinus the Hermit (Douai, 1626), edited by Raisius. Archard lived about 1140. Cave calls him "philosophus insignis et theologus illustris." He also wrote some short Sermons to the novices. See Dupin, Bibliotheque Univ. ii, 374; Cave, Hist. Lit. ii, 218.
