The catch is that nobody has been able to find it for some time. A font, in this context, is the stone basin used for administering baptism, and they are often among the most durable furnishings a church can possess, surviving long after walls have collapsed and rooflines have gone. That one has been effectively swallowed by a building it presumably predates in decay is an oddly fitting kind of disappearance.

The font was recorded by the antiquarian W.G. Wood-Martin in 1882, who noted it as a broken font just inside the door of the church. Wood-Martin was a prolific documenter of Sligo's archaeology and antiquities in the Victorian era, and his observations form a significant part of what is known about sites in the county from that period. By the time later surveyors came to verify the font's location, the interior of the church had become so heavily overgrown that the object could not be found at all. It had not necessarily gone anywhere; it had simply been consumed by vegetation and time.
