This is a rare paper astrolabe by a famous French maker from the sixteenth century. Philippe Danfrie is known from a relatively large number of surviving instruments, including others in this Museum, and from books. All his engraving work shows great skill, and his engagement with the print trade meant that he was at ease with engraving either directly or in mirror-image. Here he has used the latter skill to produce an astrolabe in inexpensive materials and that could be produced quickly in quantity from copper-plates. This type of astrolabe was probably much more common than would appear from surviving numbers.
