In Collectanea de Rebus Hibernicus, his 1791 disquisition on Irish antiquities, Charles Vallancey describes a group of sepulchral stones on the Hill of Tara, one of which is inscribed BELI DIVOSE, “To Belus, God of Fire.”

Vallancey goes into some detail interpreting this as an altar to Baal. It turned out later that a wanderer had lain upon the stone and idly carved his name and the date upside down: E. CONID 1731.

Vallancey’s reaction is not recorded.
