Cosmological mosaic - located in the house of Mitreo, in Mérida, Spain.
It is dated in the first century and is one of the best works of Roman civilization, because it represents the philosophical conception of the world and the forces of nature. The mosaic is divided into three parts: sky, earth and sea.
In the sky are Saeculum, the time represented by the centuries and their children; Caelum, sky and Chaos; Polum, the north pole with the world behind him; Tronitum, thunder; Oriens the sun; Ocassus. It also includes the winds and clouds: Notus, the wind the south, with Nubs, the clouds; Zephyrus, west wind with Nebula, fog; Eurus, west wind and Boreas, the north wind.
On the earth the personifications are Mons, a sacred mountain in whose lap Nix rests, the snow.
And finally Oceanus, the ocean; Tranquilitas, the calm sea; Copiae, the riches generated by the sea or that are transported by it; Pharus, the lighthouse that helps navigators, Navigia, navigation and Pontus, the sea.
