First of the Northumbrian Nuns
Hieu's place in English monastic history rests on her being among the first, and by several accounts the first, woman in Northumbria to take the monastic habit. The veil was given to her by Aidan of Lindisfarne, who as missionary bishop drew the kingdom toward the Christian faith and fostered its earliest monastic foundations. Her elevation to the rule of Hartlepool, an early house organized in the Irish manner, set a pattern that later Northumbrian women would follow.
The continuity of her work is underscored by her successor at Hartlepool. When Hieu relinquished that office, Hilda was appointed in her place and established there a rule of regular monastic observance, before founding the great monastery at Whitby. In this way the religious life that Hieu inaugurated did not end with her departure but was carried forward and deepened by those who came after her.
