Aelred, abbot of the Yorkshire Cistercian abbey of Rievaulx from 1147 to 1167, wrote six spiritual treatises, seven historical treatises, and 182 liturgical sermons, most of which he delivered as chapter talks to his monks. Translations of the first twenty-eight of these sermons appeared in
The First Clairvaux Collection, Advent-All Saints, published in 2001. The current volume contains eighteen sermons given on feasts beginning with the Nativity and concluding with a sermon for All Saints.
