The Evolution of Fire-Clocks in Time Measurement
In the context of time measurement, the last paragraph highlights the existence of various types of fire-clocks used throughout history. The paragraph discusses how different cultures and societies have developed innovative ways to measure time through the burning of materials.
Fire-clocks as a Timekeeping Method:The passage mentions the fire-clock used by Chinese messengers who placed a lighted piece of joss-stick between their toes to act as both a timepiece and an alarm-clock. This illustrates the resourcefulness and ingenuity of ancient civilizations in utilizing fire as a means of time measurement.
Diversity in Fire-Clock Designs:Furthermore, the paragraph introduces the fire-clock employed by Pacific Islanders, where oily nuts of the candle-nut tree were burned off to mark the passage of time. This showcases the diversity in the design and function of fire-clocks across different regions.
Historical Significance:By acknowledging the existence of multiple types of fire-clocks for timekeeping, the paragraph underscores the historical relevance of such inventions in human society. These early methods of time measurement paved the way for the development of more advanced clocks and chronometers.
