Beware the Ides of March
The Norman chancel arch at Glympton in Oxfordshire has the following interesting and tantalising inscription carved on its jamb: 'Dedicatio hujus templi Idus Martii' i.e. 'this temple was dedicated on the Ides (15th) of March'. Sadly the stone with the rest of the date has been replaced, but presumably the dedication took place on a 15th of March sometime towards the end of the 12th century, if the style of the arch is anything to go by.
Glympton church, with its perfectly preened churchyard stands in the middle of a north Oxfordshire estate owned by a Saudi prince.
