A marble wall memorial on the north chapel north wall, erected 1742, comprises an engraved plaque, this below an entablature with floriate details topped by a cockerel.
Goat and cockerel sacrifices are made from time to time by devotees whose vows were fulfilled ranging from education, health, matrimony, business, childless couples and many other matters.
A cockerel seeking food finds instead a precious gemstone, recognises the worth it has for others, but rejects it as being of no practical use to himself.
