"Planetary cycles remain the basis of a cyclic time where, from one conjunction to the other, a return of the same occurs, which gives a sense of history as a continuous link of events stretching across time and space. It is upon the Uranus Neptune conjunction in the first degrees of Sagittarius in 1479, through which Jupiter and Saturn also moved from 1485 to 1488, that the great explorers take over the oceans: Dias passes the Cape of Good Hope and Christopher Columbus is just about to land in America (1492). The globe as a whole is embraced by man who starts travelling it : it is the beginning of the great expeditions which will lead Europe to the colonization of the globe. We will see the continuation of this movement when the same planets move through Sagittarius. In the same manner, an extraordinary industrial revolution takes place, giving birth to our modern society, when the following conjunction occurs in 1821 in the first degrees of Capricorn."
