Mourier is a geometric alphabet designed by Eric Mourier in 1971 following a strict set of rules. The font is based on a square of 7 x 7 units and made of unclosed lines. The first and only use of the lead-cast font was on the booklet 'The Myth about Bird B', a leporello design by Mourier and written by Knud Holten (a poet).

In 2002, Sébastien Hayez adapted the typeface as a digital font, with the approval of its original designer (thanks to him), which was afterwards published as part of the Velvetyne Type Foundry collection in 2011. Then, in 2020, Ukraininan designer Alex Ash (Alexander Kondratenko) proposed a Cyrillic alphabet expansion of the font, of which he had imagined the capitals. Ariel Martín Perez took this opportunity and developped lowercase letters for Latin and Cyrillic scripts (with feedback from Alex Ash for the Cyrillic), added diacritics and symbols, mastered the font and also created several sets of alternates.
