FS Siena is a typeface with history, and not just in the sense of having its origins in classical Roman lettering. Fontsmith founder Jason Smith first committed it to tracing paper while still at college, instinctively redrawing letterforms based on Hermann Zapf’s Optima according to ‘what felt right’. When Krista Radoeva took up the challenge to edit and extend the typeface, she and Jason were determined to preserve its subtly nonconformist and eclectic spirit. Like a great dish, there are individual components throughout the character set that all add flavour, and need to be balanced in order to work together. The smooth connection of the ‘h’ ‘m’ ‘n’ and ‘r’ contrasts with the corners of the ‘b’ and ‘p’. The instantly recognisable double-storey ‘a’ – the starting point of the design – contrasts with the single-storey ‘g’ and the more cursive ‘y’. And only certain characters – ‘k’, ‘w’, ‘v’ and ‘x’ in the lowercase and ‘K’, ‘V’, ‘W’, ‘X’ and ‘Y’ in the caps – have curved strokes.
