Inscribed stone in Limerick City,irishtown

Inscribed stone in Limerick City,irishtown: a stone plaque set in the wall of St. John's graveyard, recording 1650 gifts from John Creagh, David Rochford and James Bousfield toward the city's outworks. That is all the facts give. The wall still stands beside a working church, and the names remain legible enough to be read by someone passing in a hurry. What is missing is the shape of the room where they agreed to pay, the weight of the coins, and whether the outworks were finished before the gift became a joke in another man's mouth.
