The mysterious part of the story is how Rahere, a simple gentleman, if not a jester, was able to raise this splendid structure and to found so noble a hospital. For, even supposing the hospital and priory to have been at first small and insignificant, the church itself remains, a monument of lavish and pious beneficence. The story, in order to account for the building of so great a church, goes off into a drivelling account of how Rahere feigned to be a simple idiot. A great many people every year visit this noble church, now partly restored. Very few of them take the trouble to step round to the back of the church. Yet there are one or two things worth noting in that nest of low courts and squalid streets. Cloth Fair, for instance, still possesses a few of its old timbered and gabled houses. But on the other side a small portion of the old monastery church-yard yet remains, and, in a row of two or three cottages, each with a tiny garden in front: a cottage-garden close to Smithfield--survives a memory of the garden which once stretched over this monastery court.

But the noble foundation of the Holy Trinity, Aldgate, was due to Matilda, queen of Henry I., who also founded St. Giles's Hospital, beside St. Giles-in-the-Fields. And the priory of St. John of Jerusalem, the chief seat in England of the Knights Hospitallers, was founded in the year 1100, by Jordan Briset, and Muriel, his wife.
