Provenance
It has been extracted from a copy of the
book Astrolabium, by Johannes Angelus (Augsburg, 1488), where
it was stuck between the front board of the contemporary
leather binding and the flyleaf. The book (sold separately by
Dr Weil, a London dealer) was from the library of Prince
Liechtenstein, whose ancestors were Austrian nobility. The
maker, Hanns Herghamer (the modern German surname Herkamer),
is an otherwise unknown amateur or scholar who obviously made
it for his own use.
