Aelred of Rievaulx was born c.1110 in Hexham in Northumberland, one of three sons of a priest named Eilaf. (Archbishop Anselm of Canterbury's prohibition against clerical marriage was very recent.) Although priests still had sons, a 1095 order from the Council of Claremont forbade the sons of priests to become priests (the idea was to prevent inheritance of benefices, since a bishop or higher-ranking prelate should decide where a benefice goes when a priest dies).
He would have been educated at the cathedral school at Durham. We know he spent several years at the court of King David I of Scotland, and was there long enough to rise to the title echonomus, a word related to "economy" and indicating that he was a steward or seneschal, possible the steward of the king's household, managing all of the "below stairs" members of staff. While in this role, Walter Daniel tells us of an incident where a knight harassed him and used a degrading sexual slur. Daniel uses this anecdote as an example of Aelred's capacity for forgiveness, but the incident seems to have made Aelred depressed and disillusioned with court life.
On a mission for David to Thurstan, Archbishop of York, Aelred learned of Rievaulx Abbey, founded only two years earlier by monks from Clairvaux Abbey in northeastern France. Aelred realized that a religious life was his true calling, and joined Rievaulx. A few years later he was part of a delegation to Rome to see Pope Innocent II. The purpose was to present northern England delegates who opposed the election of Henry de Sully as Archbishop of York; although de Sully was an abbot, his main qualification was that he was a nephew of Stephen of Blois, whose seizing of the throne of England caused The Anarchy. Their delegation was successful.
After Rome, Aelred in 1143 was made abbot of Revesby Abbey in Lincolnshire, founded that year as a daughter house of Rievaulx. Not long after, in 1147, he was made abbot of Rievaulx itself. According to his biographer, Aelred "doubled everything" at Rievaulx. The buildings, the members, the resources—all increased under Aelred at what was an already flourishing complex.
Tomorrow, we'll talk more about Aelred's leadership and authorship. See you then.
