Solus has a structure of straight, regular serifs reminiscent of slab-serif typefaces of the nineteenth century, but with a reduced build giving an impression of crispness.[6] 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'.[7][8][9]James Mosley describes Solus as "essentially a mechanistic type — a ‘light Egyptian’", a conclusion also reached by editor Robert Harling in his book on Gill's work.[10][a]
Solus was not particularly popular during the metal type period, which Harling suggests was 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.[12] Gill's Joanna, designed some years later in a similar style but with an italic, has become much more popular.[10]
Solus has not been digitised by Monotype; an unofficial revival has been made by the company K-Type.[10][13] Financier, by Kris Sowersby, is a respected revival loosely influenced by Solus, Perpetua and Joanna.[14][15] Its optical size designed for small-size text is influenced by Solus and Joanna more while its display size more recalls Perpetua.[16][17]

^Walter Tracy in contrast commented: "it is hard to accept the suggestion that the egyptian form was in Eric Gill's mind...[Solus] is really no more than a Perpetua-like roman unhappily fitted with a thickened version of the serifs of Monotype Bodoni 135, recommended to Gill by Stanley Morison."[11]
