The saphea projection in Europe

The European history of the universal saphea projection before its popularisation by Gemma Frisius in the 16th century was discussed by Emmanuel Poulle, “Un instrument astronomique dans l’occident latin, la saphea,” in A Giuseppe Ermini, vol. I (Spoleto, 1970) = Studi Medievali, 3rd series, X, part 1 (1969), pp. 491-510.

The Museum's collection includes two examples of these early instruments, one of which was adapted around 1600 and which closely matches the images in Zeelst and Stempel's work on the astrolabe.
