 The font is still used for baptisms today; there is normally a small charge for viewing it.The font was traditionally attributed to Renier de Huy, a 12th-century metalworker and sculptor, but this, and even the Mosan origin of the font, have been questioned and alternative theories advanced.Nothing is known of Rainer's life other than that he was mentioned in a document of 1125 as a goldsmith, but a 14th-century chronicle mentions him as the artist of the font.
