Misericords outside of the UK
Although this probably reflects more on the dissolution of the monasteries in the mid 16th century, and King Edward VI’s vehement hatred of Catholicism, British churches stopped creating misericords by the end of the 16th century, whereas continental Europe, continued the tradition well into the 18th century.
One difference that is worth noting between British (and Irish) and Continental misericords is the supporters - British misericords are likely to have supporters, the earlier examples are usually floral or leaf designs, whilst later misericords such as those at Beverley Minster, Ripon Minster and Manchester Cathedral have supporters which are an extension of the main design. Continental misericords, with limited exceptions, do not have supporters.
