Saint Bernard was born in 1091, and died in 1153. His life thus almost coincides with the central portion of the Middle Ages. He saw the First and Second Crusades, the rising liberties of the communes, and the beginnings of scholasticism under Abelard. A large Church reformation and the noblest period of monasticism occurred in his day, and received deep marks of his genius.
He was the son of Tesselin, a wealthy feudal baron of Burgundy, remarkable for his courage, piety, justice and modesty. Alith, his mother, was earnest, loving and devout, and full of humility and charity. His earliest years were passed amid the European fervour of the First Crusade; and as he grew from boyhood into youth--at which time his mother died--he made choice of the monastic profession. His friends vainly tried to tempt him aside into the pursuit of philosophy; but his commanding personal ascendancy brought his brothers and friends to follow him instead into the religious life. Having assembled a company of about thirty chosen spirits, he retired into seclusion with them for six months, and then, in 1113, at the age of twenty-two, led them within the gates of Citeaux.
This community, founded fifteen years before, and now ruled by Stephen Harding, an Englishman from Dorsetshire, was exceedingly austere, keeping Saint Benedict's rule literally. Here Bernard's uncompromising self-mortification, and his love of, and communion with, Nature, showed themselves as the chief characteristics of his noble spirit. "Believe me," he said to a pupil, "you will find something far greater in the woods than you will in books; stones and trees will teach you that which you will never learn from masters." The arrival of Bernard and his companions was a turning-point in the history of Citeaux; and the monastery had to send out two colonies, to La Ferté and Pontigny, and in 1115 a third, under Bernard himself, to Clairvaux. Here, in a deep umbrageous valley, traversed by a limpid stream, the thirteen pioneers built a house little better than a barn. Their privations were great. Beech-nuts and roots were at first their main support; but soon the sympathy of the surrounding country brought sufficiency for their frugal needs. Bernard was consecrated Abbot of Clairvaux by the Bishop of Chalons, the renowned William of Champeaux, with whom he established a deep friendship.
