DIRECT OBSERVATIONS:
1. Astrlabes and Quadrants: These instruments were used by ancient astronomers to measure the positions of celestial objects, such as stars and planets, to determine their motion and the movement of the heavens.
2. Mechanical clocks: Developed in the Middle Ages, these devices helped track time and measure the time intervals needed for objects to move from one point to another.
3. Odometers: These devices were attached to vehicles and measured the distance travelled, providing a rudimentary way of mapping motion.
4. Compasses and Sextents: These instruments aided navigators and explorers by providing directional reference and the ability to measure angles and distances.
5. Pendulums: Scientists studied the motion of pendulums and their relation to gravity, eventually leading to the development of accurate clocks.
CELESTIAL OBSERVATION:
People used the study of celestial bodies to understand and map the motion of objects on Earth.
1. Lunar and Solar Eclipses: Observing the exact timing and patterns of lunar and solar eclipses allowed people to understand the motion and positions of celestial bodies.
2. Constellations: Ancient cultures relied on the patterns and movements of stars in constellations to measure the passage of time and to chart the position of celestial bodies.
3. Solar Calendar: The development of calendars was based on the observed motion of the sun, marking the days, months, and seasons.
4. Astrolabes and Celestial Spheres: These instruments were used to visualize the motion of celestial objects, providing insights into the movement of the heavens.
By combining direct observations and celestial study, people were able to map the motion of objects, laying the groundwork for the development of more advanced mapping technology in later times.
