Luach Erech Kol Yemei HaShanah [times of sunrise and sunset in Jerusalem and elsewhere].

Extremely rare. Halevy writes “Yekar hametziuth beyother” - and only is aware of this books’ existence at all based upon a listing in Ben Menachem’s, BeSha’arei Sepher (p. 151). Schwarz writes in his introduction here that he took care to watch the sunrise more than four thousand times in order to ensure that his calculations were correct. Times are noted for locations throughout Eretz Israel as well as for cities in the neighboring Near East such as Aleppo and Baghdad. The final leaf records times for the major cities of Europe as well as New York. A Talmudic and Biblical scholar of note, Joseph Schwarz settled in Jerusalem in 1833 and devoted himself to the study of the topography, geography and natural history of the Holy Land. Famed for his work Tevu’oth Ha’aretz (1845), Schwarz is considered the first Jewish geographer of modern times. See Y. Ben-Arieh, The Rediscovery of the Holy Land in the Nineteenth Century (1979) pp. 104-07.
