Lydian is Warren Chappell’s almost calligraphic sanserif, designed for ATF in 1938. Lydian Cursive, done by Chappell in 1940, is much freer and more calligraphic.
A light roundhand with mildly clubbed terminals on the capitals. It was expertly transferred from an engravers’ pattern plate to the Fotosetter Intertype about 1955.
