V. CENSO.
After the return of St. Robert to Molesme, A. succeeded him as abbot (1009-1109). In 1100 he obtained from Pope Paschal II the approval of the new monastic Order, to which he also gave the first constitutions and which he dedicated to the Virgin. He saw the reform of monastic life in a return to the primitive spirit of the Rule of St. Benedict: he especially inculcated simplicity of customs in daily life, the poverty of the individual monk, manual labor, the exercise of hospitality, and the *opus Dei*.
After nearly ten years of government with very strict discipline, he died a holy death on 26 January 1109. A. was considered a saint in the Cistercian Order from time immemorial. His name appears in the most ancient catalogues of saints and blesseds of the same Order. By decree of 3 January 1701, the Sacred Congregation of Rites approved the office in honor of A. and permitted its celebration by the Cistercians, a feast which in 1738 was fixed on 26 January.
