Pope Innocent II writes to King David I, telling him that Osbert [of Clare], prior of Westminster, has asked him to write to the king on behalf of the monks of Westminster, so that the king’s goodness towards them may be more strongly established. The pope has learned that David’s sister, Queen Matilda, lies buried in the sacristy of Westminster Abbey, and that David supplies the monks 30s. on the anniversary of her burial; moreover, the monks revive the memory of David’s father and mother each year by celebration. The pope urges David to establish the land to Westminster Abbey from which his payment is made, lest it should cease on his death, if not previously established by his royal authority.
