Lithos is a glyphic sans-serif typeface designed by Carol Twombly in 1989 for Adobe Systems.

Lithos is inspired by the unadorned, geometric letterforms of the engravings found on Ancient Greek public buildings.

[non sequitur][citation needed] Twombly also designed Trajan and Charlemagne based respectively on ancient Roman and Byzantine inscriptions.

OpenType features include alternates, case forms, proportional lining figures, small caps.

[3] Lithos is widely used in South Park, e.g. the flag with the text "Welcome Kathie Lee" in "Weight Gain 4000", the Terrance and Phillip Show logo", etc.
