Towards the end of the eighteenth century neoclassicism led to architects increasingly incorporating ancient Greek and Roman designs in contemporary structures. Historian James Mosley, the leading expert on early revival of sans-serif letters, has found that architect John Soane commonly used sans-serif letters on his drawings and architectural designs. Soane's inspiration was apparently the inscriptions dedicating the Temple of Vesta in Tivoli, Italy, with minimal serifs. These were then copied by other artists, and in London sans-serif capitals became popular for advertising, apparently because of the "astonishing" effect the unusual style had on the public. The lettering style apparently became referred to as "old Roman" or "Egyptian" characters, referencing the classical past and a contemporary interest in Ancient Egypt and its blocky, geometric architecture.
