Far fewer people pause in the churchyard itself, where a quieter kind of memorial survives above ground: a stone slab bearing the Christogram IHS, that familiar monogram derived from the Greek name for Jesus and widely used in Catholic and Anglican devotional contexts from the medieval period onward, alongside a carved inscription in Roman letters commemorating a man named Barth Hadsor.

Hadsor died in 1669, a moment in Dublin's history when the city was still reshaping itself after the upheavals of the mid-seventeenth century. The monument was recorded in the sixth volume of the Memorials of the Dead, a painstaking survey published between 1904 and 1906 that catalogued inscriptions across Irish graveyards at a time when many were already eroding or being lost. Without that record, a stone like this one, modest in scale and easy to walk past, might have slipped entirely from notice. The survey entry is brief, as such entries often are, giving little more than the name, the date, and the decorative detail of the IHS symbol, but it is enough to anchor the memorial to a specific individual in a specific year.

St Michan's is located on Church Street in Dublin's north inner city, and the churchyard is accessible when the church grounds are open. The slab itself is the kind of thing that rewards a slow circuit of the yard rather than a direct approach; wall monuments and grave slabs from this period can be worn, discoloured, or partially obscured by lichen, and the inscription in Roman letters may require a moment's adjustment of angle and light to read clearly. The IHS monogram, carved above the text, is usually the easiest element to make out first. Given that the monument was already considered worth documenting over a century ago, checking its current condition before visiting is sensible, as churchyard memorials of this age are vulnerable to weathering and occasionally to displacement during ground works.
