Before mechanical clock.

Our ancestors lived by hunting and gathering, living in close contact with nature. Among them, they realized that we can measure a day by the shadows of things illuminated by the sun. The first watch of mankind was a sundial. They discover the regularity of the sun and wear the feeling of days, months, years, seasons. It seems that the pyramids existing in Egypt and the pillar monuments were used as sundials.


わたしたちの祖先は、狩猟採集をして暮らし、大自然と密接に関わりながら生活をしていた。そのなかで、太陽に照らされた物の影によって1日を計ることができることに気付いた。人類最初の時計は日時計だった。彼らは、太陽の規則性を発見し、日・月・年、季節という感覚を身に着けていく。エジプトに現存するピラミッドも、方柱碑も、日時計として用いられたと思われる。
