The frontispiece shows a mezzotint of Jacob de Castro Sarmento (1692–1762), a notable physician and pioneer of inoculation. The constraints of the Portuguese Inquisition led Castro Sarmento, who was of Jewish descent, to exile in London in 1720. There he was made a Fellow of the Royal Society in 1729, one of 25 Portuguese Fellows elected between 1668 and the early nineteenth century. His many contacts in London and across Europe placed him firmly among the leaders of the country's estrangeirados in the struggle to open Portugal to international trends in science and learning. His life and work are the subject of a recent book by Júlio de Andrade and Maria Fernanda Guimares: Jacob de Castro Sarmento (Nova Vega, Lisbon, 2010).
