Being the astronomy fanatic that I am, it is really interesting to learn about all the various ancient tools used by the founding fathers of the science. Todays technology has dramatically changed astronomy with high-tech equipment like powerful telescopes and satellites. Old tools are still being collected and even used due to their significant contributions to the science. Here are just some of my favorites:
Zodiac Globes
These globes were used in the early days to help determine astronomical arrangements and motions. A zodiac denotes an annual cycle of twelve stations along the ecliptic. The path divides the sun through the constellations into twelve equal zones of celestial longitude.
Astrolabe
This unique instrument was used by Greek astronomers around 200 B.C. This item is used to take the altitude of the sun or stars and also used to help find direction. An astrolabe is a very ancient computer-like tool used for astronomy problems and is to this day admired for it’s unique capabilities and contribution to the study of astrology.
The Sundial
Sundial is a device that measures time by the position of the sun by the sun casting its shadow on a specific place. If a sundial is on the correct time, the style must point towards true North.
