As time wore on, quadrangular, 'H' or 'E' shaped floor plans became more common, with the H shape coming to fruition during the reign of Henry VII's son and successor. It was also fashionable for these larger buildings to incorporate 'devices', or riddles, designed into the building, which served to demonstrate the owner's wit and to delight visitors. Occasionally these were Catholic symbols, for example, subtle or not so subtle references to the trinity, seen in three-sided, triangular, or 'Y' shaped plans, designs or motifs. Earlier clerical buildings would have had a cross shape so as to honour Christ, such as in Old St Paul's and the surviving York Cathedral, but as with all clerical buildings, this was a time of great chaos and revolution catalyzed by Henry VIII's Reformation.
