As with the Sans, Cymru Serif draws on historic Welsh typography such as the Black Book of Carmarthen and the Red Book of Hergest, as well as Celtic pub signage. However, the Serif design also looks further afield — with influences from Dutch calligraphy and even languages such as Arabic and Icelandic for their more exuberant serif forms. The open connections in the “B”, “K”, “P”, “R”, “d”, and “&” reveal this calligraphic and gestural influence, while the curved “d” form speaks back to the original Sans design.
