Regimento do estrolabio e do quadrante : tractado da spera do mundo : reproduction fac-similé du seul exemplaire connu appartenant à la Bibliothèque Royale de Munich
A 1914 Munich facsimile, edited by Joaquim Bensaúde, of an early Portuguese manual of the astrolabe and quadrant bound with a vernacular Sacrobosco sphere treatise, issued for historians of navigation and astronomy. The plates are coarse woodcut circle diagrams — hemispheres split by equinoctial lines, a banded zodiac ring with planetary signs, eclipse and star-ringed orb schemes — captioned in blackletter Portuguese, useful as high-contrast cosmological line motifs.
