Rahere at length cast aside his assumed idiotcy, and began his Apostolic work by instructing with cunning of Truth, and saying the word of God in divers churches, and constantly exhorting the multitude both of clerks and laity to follow and fulfil those things which were of charity and alms deed. He did not make these appeals in vain, and his purity was not unknown at Court, and after patient waiting and labour, his church was founded in March, Anno Domini 1113.

The edifice was of comely stonework tablewise, and an hospital house a little longer off from the church, which was founded for the service of the poor, the sick, and pregnant women, with the care of such children, till seven years old, as lost their mother at birth. The year of its completion differs as given by various authorities, but about 1123 is the generally received date at which the Priory was finished. The completion of the work under all the circumstances and difficulties, created a great amount of wonder and admiration, mixed with superstitious awe, its grandeur astonishing the beholders by its contrast with the desolation that previously reigned around.

Rahere was appointed first Prior. He was Prior 22 years and 6 months, and was succeeded by Thomas, one of the Canons of the church of St. Osyth, who continued prelate about 30 years; in age 100 winters when he died. We then have Gregory, Canon of St. Osyth, made Prior 1213, who a few days after became monk at Abingdon.
