In the centre aisle of St. David's Church in Naas, set flush into the floor where generations of feet have passed over it, lies a black, shaly rectangular slab measuring just over 1.7 metres long and 0.63 metres wide. Floor slabs of this kind were a common enough feature of medieval and early modern churches, where burial within the building itself was a mark of social standing, and the stone would have served both as a grave marker and as a permanent, walked-upon memorial. What makes this one quietly compelling is how much it almost tells you: it commemorates a woman named Susanna Heale, and the date of her death begins with 168, the final digit now lost or illegible, leaving her in a decade somewhere between 1680 and 1689, her exact year unrecoverable.
