Guardare il cielo per vivere la terra

The ancient civilizations recognized the possibility to measure time in the cycles of the stars motion, mainly to establish the religious festivals and the activities linked to agriculture. The universe has become a reference for space and time, thanks to the application of the logic of appearance, and has allowed man to feel part of a "whole" that he finally began to understand. Watching the course of the stars and searching the rhythms of the major and minor cycles of the heavens, perpetually recurring, has led the most ancient Mesopotamian civilizations to discover the basics of an exact science concerning the observation of the sky. About two thousand years later, the ancient Egyptians linked the study of the sky to its representation giving, besides beautiful figures, a picture of the vault of heaven of that period. The Greek culture first, and then, in particular, the Arab-Muslim one were able to "measure" what is far above us, allowing man to use this knowledge to say "what is above, is below" (microcosm and macrocosm). Observing, representing, measuring: the eternal cycle of the history of man.
