Clarendon

Clarendon is a slab serif typeface that was released in 1845 by Thorowgood and Co. (or Thorowgood and Besley) of London, a letter foundry often known as the Fann Street Foundry. The original Clarendon design is credited to Robert Besley, a partner in the foundry, and was originally engraved by punchcutter Benjamin Fox, who may also have contributed to its design. Many copies, adaptations and revivals have been released, becoming almost an entire genre of type design. Clarendon has a bold, solid structure, similar in letter structure to the "modern" serif typefaces popular in the nineteenth century for body text (for instance showing an 'R' with a curled leg, and ball terminals on the 'a' and 'c'), but bolder and with less contrast in stroke weight. Clarendon designs generally have a structure with bracketed serifs, which become larger as they reach the main stroke of the letter.
