- Uncials and half uncials were in widespread use as book scripts (especially in Ireland) between the 4th and 9th centuries. Victor Hammer, a German type designer and calligrapher, was responsible for a revival of these letterforms in the first half of the 20th century. American Uncial (1945), his best-known type, was issued by Stempel in 1952. Uncials are hardly ever seen nowadays, except perhaps as nostalgic faces to advertise handmade crafts, for example.
