Designed, cut, and cast by Paul Hayden Duensing for his private press, as a revision of his earlier Quadrata (1970) [McGrew 1993].

Adopted by Formatt for dry-transfer lettering and shown in their 1974 catalog as Stonehenge. Solotype offered it under the name Diderot [Solo 1992]. Also known as Merlin [Solopedia].

Digital adaptations include VT Quadrata (VintageType, before 2000, based on Duensing’s original, discontinued), Shiver Me Timbers NF (2006), and the freebies Satans Minions (Mickey Rossi, 2000) and Moria Citadel (Russ Herschler, 2011, based on Stonehenge, used for sample).
