официальная датировка памятника совершенно не соответствует изображенному костюму,
скорее всего, более древняя плита с фигурами была использована для саркофага 16-го века
датировать изображенный костюм можно 1350-ми годами - появилась открытая бригандина, но подолы подклада и кольчуги еще длинные
изображенный комплекс очень похож на немецкие комплексы этого периода (см. G0001 - открытые бригандины с поперечными полосами, такая же длина подклада, кольчуги, короткий кольчужный рукав, у P0031, 1359 - такое же положение правой руки)

The MacGillpatrick Chapel was attached to the church and contains the tomb of John MacGillpatrick and his wife. It dates from the early 16th century and was carved by Rory O Tunney. The tomb supports the double effigy of MacGillpatrick and his wife and the chest is decorated with images of window tracery and lierne vaulting in low relief.

Brian na Luirech Mac Giolla Patraic, Lord of Upper Ossory (? – 1537)
Brian na Luirech married Inghen Ni Morda, a daughter of a member of O'Moore family in Leix. They had two sons, Brian Oge and Diarmaid (Dermot) and one daughter Catherin. Historical records state that he was a member of the "Shirts of Mail;" however, the significance of this organization is not known. Based on the date of construction, he or one of the members of his family built Ballaghmore Castle. His sarcophagus can be found in the MacGillpatrick Chapel near the Round Tower at Granefertagh in County Kilkenny. Some websites identify this sarcophagus as belonging to John MacGillpatrick, which is most likely not correct. The tomb has effigies of Brian in armor and his wife with a fine gothic carving.
