I was interested to find out more about the typeface Trajan, as used by Oliver Hoare and his designer, Charles Marsden-Smedley, as the font for his exhibition. The answer is that it’s a modern font, one of a number of modern, but classical typefaces devised by Carol Twombly in the late 1980s for Adobe when digital typography first came in: based, as one might guess from the name, on the stone lettering on the base of Trajan’s column. It was a style of lettering which was apparently much admired in 1950s Russia when there was a revival of interest in traditions of typographic design.

The combination of Trajan’s Column and the surname Twombly raises the question as to whether the designer of the font was a relation of the great Rome based American painter
Yes, I wondered that too. There’s a recent biography of her which I haven’t seen. Charles
No mention of her being related to Cy on her wiki page.She’s given up designing type and is working in other areas of art and design.
I’ve always loved this font. It has kept the feeling original relationship of the brushed letters that were then incised into the stone by anonymous Roman stoneworkers.
