ROGERS (Francis M.). PRECISION Astrolabe: Portuguese Navigators and Trasoceanic Aviation. Lisboa. 1971. - ROGERS (Francis M.) PRECISION Astrolabe: Portuguese Navigators and Trasoceanic Aviation . Lisboa: Academia Internacional da Cultura Portuguesa, 1971. XXXII, 398, [2] pp.: il.; 235 mm. This is a monographic study of Francis Millet Rogers (New Bedford, Massachusetts, 1914 - Morristown, 1989), professor of Romance languages and literatures at Harvard from 1945 until his retirement in 1981, where he chaired the Department of Romance Languages and held the Dean's Degree at the Graduate School of Arts and Sciences. A descendant of Azorean emigrants, Rogers dedicated a substantial part of his academic work to the history of Portuguese expansion and to Lusophone communities in the Anglophone world, and was a Commander of the Order of Prince Henry the Navigator. Precision Astrolabe examines the contribution of Portuguese navigators to the development of the precision astrolabe as an instrument for astronomical navigation, tracing the technical connection between the nautical practices of the 15th and 16th century expansion and the transoceanic aviation of the 20th century. ⚑ Auto-translated via Google Translate
