Astronomy
Original Latin title: "Sidereus Nuncius." This was the first short astronomical treatise published based on observations made through a telescope.
Johannes Kepler's "Dioptrice" (1611) provided the theoretical explanation for how the telescope worked, supporting Galileo's practical observations.
Christ's Hospital is a historic English school; Carlos was the first to provide a complete English rendering of this foundational scientific text.
