A mirror for mathematiques: : a golden gem for geometricians: a sure safety for saylers, and an auncient antiquary for astronomers and astrologians. Contayning also an order howe to make an astronimicall instrument, called the astrolab, vvith the vse thereof. Also a playne and most easie instruction for erection of a figure for the 12. houses of the heauens. A work most profitable for all such as are students in astrenomie, & geometrie, and generally most necessarie for all learners in mathematicall artes. The contents of which booke you shall find in the next page. (1587)
