Serifs originated in the Latin alphabet with inscriptional lettering—words carved into stone in Roman antiquity. The explanation proposed by Father Edward Catich in his 1968 book The Origin of the Serif is now broadly but not universally accepted: the Roman letter outlines were first painted onto stone, and the stone carvers followed the brush marks, which flared at stroke ends and corners, creating serifs. Another theory is that serifs were devised to neaten the ends of 2001:7C0:2041:1AA:0:0:0:DBlines as they were chiseled into stone.
