This font family is inspired on printed work made by the Elzevir family back in the XVIIth century at Leiden (NL). They worked with material from several type designers, but further investigations sends us to the tracks of one in particular: Robert Granjon. Granjon italics were way ahead of his time, making some really beautiful signs like swashy ampersands and minuscule v letters. This font also contains old style figures in the same fashion as they were printed, like the flipped number 8 and open forms in 6 and 9. This is as much a revival as an original design, because of their weights bold and heavy (both with italics) that were inspired on some titles. In this font you can also find a lot of ligatures, small caps, diacritics and even a fleuron for each weight and variation.

Leidener came up from two books: Constantini Imperiatoris (1611) and Exercitationum Mathematicarum (1657), printed by Louis and John Elzevir on their Leiden Workshop, back in the day.
