The roman designs of Garamond which are his most imitated were based on a font cut around 1495 for the Venetian printer Aldus Manutius by engraver Francesco Griffo. This was first used in the book "De Aetna", a short work by poet and cleric Pietro Bembo which was Manutius' first printing in the Latin alphabet. Historian Beatrice Warde has assessed "De Aetna" as something of a pilot project, a small book printed to a higher standard than Manutius' norm. Among other details, this font popularised the idea that in printing the cross-stroke of the 'e' should be level instead of slanting upwards to the right like handwriting, something imitated in almost all type designs since. French typefounders of the 16th century assiduously examined Manutius's work (and, it is thought, "De Aetna" in particular) as a source of inspiration: Garamond's roman, italic and greek typefaces were all influenced by types used by Manutius.
