Italian orientalist Carlo Alfonso Nallino (1872-1938) was professor of Arabian studies at Naples and Palermo and of Muslim history and institutions at Rome. His study of astronomy and Arabian culture at Cairo University prepared him for his three-volume translation of Al-Battani's Opus Astronomicum.
