Anselm was born in Aosta, in northern Italy, and became a monk of Bec in Normandy, where he taught theology and devoted himself to the spiritual life. After some years as abbot, he succeeded his master Lanfranc as archbishop of Canterbury. His bitter disputes with the kings of England over the independence of the Church resulted in his twice being exiled. He died at Canterbury on 21 April 1109. He is remembered for his theological learning and writings, and for organising and reforming church life in England.

Violet is a dark colour, ‘the gloomy cast of the mortified, denoting affliction and melancholy’. Liturgically, it is the colour of Advent and Lent, the seasons of penance and preparation.
