IV. Astronomical Instruments & Exhibitions
Introduction to Large Bronze Astronomical Instruments
- Elaborately Designed Equatorial Armillary Sphere
This massive instrument, weighing 5145 kilograms and standing 3.379 meters tall, is exhibited in the northeastern area of the Beijing Ancient Observatory. As the last large bronze astronomical instrument of the Qing Dynasty, it serves not just as a tool for astronomical research but also reflects the advancements in metallurgy, manufacturing, and engraving arts of that era. Its intricate engravings and complex structural design showcase the extraordinary skills and boundless wisdom of ancient craftsmen.
- Sextant
Located in the southern area of the observatory, adjacent to the equatorial armillary sphere, this sextant weighs 802 kilograms and stands 3.274 meters tall. Manufactured during the Qing Dynasty, it was a crucial tool for ancient Chinese navigation and astronomical observations. Through this instrument, ancient astronomers could accurately measure the altitude and azimuth of celestial bodies, providing precise navigation information for sailors.
- Ecliptic Armillary Sphere
Weighing 2752 kilograms and standing 3.492 meters tall, the ecliptic armillary sphere marks a significant innovation in ancient Chinese astronomical observations. As China's first independent frame ecliptic coordinate observation device, it played a vital role in ancient astronomical research. This instrument enabled astronomers to more accurately observe and record the positions and trajectories of celestial bodies.
- Theodolite
The theodolite, weighing 7368 kilograms and standing 4.125 meters tall, is a precious exhibit at the Beijing Ancient Observatory. This instrument embodies the scientific spirit of the Western Renaissance and the essence of French decorative arts, serving as a testament to Sino-Western cultural exchange. The precision and aesthetics of the theodolite have reached remarkably high levels, representing a perfect blend of ancient astronomy and art.
- Horizontal Instrument
Located at the southern end of the Beijing Ancient Observatory, this horizontal instrument weighs 1811 kilograms and stands 3.2 meters tall. Primarily used to measure the position and altitude of celestial bodies on the horizon, it held significant importance for ancient navigation and astronomical observations. Both the design and manufacture of this instrument reflect the advanced technology of ancient times.
- Another Equatorial Armillary Sphere
In addition to the previously mentioned equatorial armillary sphere, the Beijing Ancient Observatory also exhibits another one weighing 2720 kilograms and standing 3.380 meters tall. This instrument played a crucial role in ancient Chinese astronomical observations, serving over fourteen different functions. Primarily, it was used to measure the right ascension and declination of stars, providing valuable data for ancient astronomical research.
- Celestial Globe
The celestial globe, weighing 3850 kilograms and standing 2.735 meters tall, is a unique exhibit at the Beijing Ancient Observatory. Located on the top of the observatory's western side, this instrument showcases the distribution and movement of celestial bodies with the Earth as the center. Through the celestial globe, people can more intuitively understand the trajectories and relationships of celestial bodies.
- Quadrant (also known as Zenith Area Instrument)
The quadrant, also known as the zenith area instrument, is another notable exhibit at the Beijing Ancient Observatory. Weighing 2483 kilograms and standing 3.611 meters tall, it is displayed on the northwest side of the observatory's top. This instrument was primarily used to measure the distance between stars on the horizon or the distance from stars to the zenith. Both the precision and practicality of this instrument were highly regarded by ancient astronomers.
