GAMEIRO (E. da Silva). ASTRONOMIA Náutica. Lisboa. 1964. - GAMEIRO (E. da Silva) ASTRONOMIA Náutica . Lisboa: ed. autor, 1964. [8], 98, [14] pp.: il.; 220 mm. A nautical astronomy manual, self-published by the author, explaining the principles and methods for determining a ship's position through observation of celestial bodies, meridian altitude, declination, and other elements of astronomical navigation. This work, of a didactic nature, is still cited today in studies on the history of Portuguese navigation and nautical science, notably as a methodological reference for reconstructing the astronomical observation techniques used by Portuguese pilots of the 16th century, such as Pedro Nunes or D. João de Castro. A curious example of 20th-century technical marine literature in Portugal. ⚑ Auto-translated via Google Translate
