St. Botolph's Church was intended, as we have seen, to be specially connected with Pembroke College. Between them, however, there has always existed a block of buildings, while immediately adjoining the church on the other side there has arisen a College of later foundation, that of St. Mary and Corpus Christi, familiarly known as "Corpus." Unlike the other Colleges of Cambridge, this owes its existence not to the generosity of any private benefactor, but to that of two mediaeval Guilds, the Guild of St. Mary and the Guild of Corpus Christi, which combined to leave future ages this splendid memorial of their beneficence. These Guilds were merely two out of many such bodies in the Cambridge of that day; for the Guild was the Benefit Society of the mediaeval period, and every respectable citizen was enrolled in one--often, indeed, in more than one. The Guild, collectively, saw to the personal interests of its members; aided them in distress, old age, and sickness; contributed towards the expenses of their burial; and finally provided Masses for their souls. This last item ultimately proved fatal to the Guilds, which were suppressed wholesale at the Reformation, as being thus tainted with Popish superstition, and their property confiscated for the benefit of the Royal exchequer. Guilds, like our Benefit Societies, were voluntary associations, co-opting their members, and established on various bases. Earliest to rise, in all English boroughs, was the Merchant Guild, which regulated the entire trade of the town; fixing at its general meetings, called "Morning Talks," the market price of each staple commodity, and the hours and places at which it might be bought and sold, besides punishing rigorously (by fine or expulsion from the Guild) any unfair dealing, such as underselling, or "regrating,"--_i.e._, making a "corner" in any article as we should now say. Somewhat later each craft began to have its own Guild, supplanting to a large extent the older and more general organisation, whose executive insensibly became merged in the Town Council. To this day, however, the building in which that Council meets for its "Morning Talks," is called the Guildhall in most English towns. Besides the trading Guilds, there arose others organised on a definitely religious basis, the members of which were bound to special devotion in some particular direction, from which the Guild took its name. Amongst these were the two to whom we owe the existence of "Corpus"--those of "Corpus Christi" and "Blessed Mary," the former having been (in 1342) the original inceptors of the idea. The armorial bearings of the College still testify to its double origin, being, quarterly, three lilies, (the emblems of Our Lady,) and a pelican "in her piety" (_i.e._, feeding her young with her own blood, as contemporary legend imagined to be the case), as a reference to the Holy Eucharist.
