Solus is a serif typeface that was designed around 1929 by English sculptor and stonemason Eric Gill for the British Monotype Corporation.
Solus has a structure of straight, regular serifs reminiscent of slab-serif typefaces of the nineteenth century, but with a reduced build suitable for body text. Along with these characteristics, Solus bears the distinct personality of Gill's characteristic preferences in letterforms, such as the pointed end to the top left of the letter 'a'.
Solus was not particularly popular during the metal type period, which Gill's colleague Robert Harling suggests is because it was too similar to Gill's pre-existing Perpetua, not having an italic and having little appeal in display use, unlike more aggressive slab serif designs. Gill's Joanna, designed some years later in a similar style but with an italic, has become much more popular.
Solus has not been digitised by Monotype; an unofficial revival has been made by the company K-Type. Financier, by Kris Sowersby, is a respected revival loosely influenced by Solus, Perpetua and Joanna. Its optical size designed for small-size text is influenced by Solus and Joanna more while its display size more recalls Perpetua.
