There can be little doubt from the inscription in the chapel, that this worthy man was alive in the year 1454; it is still more certain from the following extract from Stow, that he was dead in 1463: "In the year 1463, the third of Edward the Fourth, Mathew Philip being mayor, in a common counsaile, at the request of the well-disposed, blessed, and devout woman, Dame Agnes Foster, _widow_, late wife to Stephen Foster, fishmonger, sometime mayor, for the comfort and reliefe of all the poore prisoners, certaine articles were established. _In primis_, that the new works then late edified by the same Dame Agnes, for the inlarging of the prison of Ludgate, from thenceforth should be had and taken as a parte and parcell of the saide prison of Ludgate, so that both the old and new works of Ludgate aforesaid, be one prison, gaile, keeping, and charge for evermore." To this Stow adds, "The said quadrant strongly builded of stone, by the fore-named Stephen Foster, and Agnes his wife, contayneth a large walking-place by ground, ... the like roome it hath over it for lodgings, and over all a fayre leades to walke upon, well imbattayled, all for ease of prisoners, to the ende they shoulde have lodging and water free without charge: as by certaine verses grauen in copper, and fixed on the said quadrant, I have read in forme following-- 'Deuout soules that passe this way, for Stephen Foster late mayor, hartely pray, And Dame Agnes his spouse, to God consecrate, that of pitty this house made for L[=o]doners in Ludgate. So that for lodging and water prisoners here nought pay, as there keepers shall answere at dreadfull domes day.'
