Explanation of the Telescope
The author of the work was Tang Ruowang (Chinese name of Johann Adam Schall von Bell, 1592–1666), the German Jesuit missionary, who, together with Jin Nige (Nicolas Trigault, 1577–1628), arrived in China in 1622. After studying Chinese in Beijing, Schall was sent on mission to Xi’an. He returned to Bejing in 1630 to continue the work of Deng Yuhan (Johannes Terentius, 1576–1630), the Swiss Jesuit missionary, on revising the calendar and devising various astronomical instruments. For his work, he received a plaque with the inscription “Imperial ...

Army Signaling
This photograph of British troops signaling is from an album of rare historical photographs depicting people and places associated with the Second Anglo-Afghan War. Signaling in the British Army at that time was performed by the Corps of the Royal Engineers. They used electric telegraphy in regions that had telegraph lines. Hand-held flags, fires for nighttime communications, and different types of non-electrical semaphores were used for campaigns in less-developed regions, such as Afghanistan. The seated soldier who is facing right uses a telescope to view the horizon; other soldiers operate ...

Dom Pedro II Observatory, Saint Thomas Island, Danish Possession in the Antilles: North Face of the Three Pavillions of the Observatory
This photograph is contained in an album that commemorates the participation of Brazil in the international effort to track the transit of Venus in 1882. This involved the establishment by the Imperial Observatory of an observatory, named after Emperor Dom Pedro II (1825-91), on the island of Saint Thomas in the Danish West Indies (present-day U.S. Virgin Islands). The transit of Venus is a rare astronomical event that occurs when Venus passes between the Earth and the sun, becoming visible in daylight against the solar disk. The transits occur ...

Observing a Solar Eclipse on January 1, 1907, near the Cherniaevo Station in the Tian-Shan Mountains above the Saliuktin Mines. Golodnaia Steppe
This unusual photograph shows preparations for observing a total solar eclipse on January 1 (14 in the Gregorian calendar), 1907, at the Cherniaevo Station settlement near the Saliutkin Mines in the Tian-Shan Mountains. Located in Central Asia near the border between China and present-day Kyrgyzstan, the range derives its name from the Chinese for “celestial mountains.” The first Russian to study the mountains was the noted Russian geographer Peter Semyonov-Tyan-Shansky, who explored the region in 1856 and 1857. The high elevation and clear dry air were ideal for observation purposes ...
