Re: Folio 57v & phebelabia...

Hi everyone,

Professor King has suggested that I look at "Deutsche und niederlandische astronomische Instrumente des 11.-18. Jahrhunderts", Ernst Zinner (Munich, 1979 reprint of a 1967 original), which contains some phebilabia.

This has also prompted me to follow up on some additional volvelle-related research leads I'd left open: I'll let you know how this goes.

Cheers, .....Nick Pelling.....

PS: GC, can you recall where you saw the 17-step / 270 degree moon-dials?
