>but also Ouranus.
in Greek mythology, the place of the Latin Janus is taken up by Ouranos, which name the Latins rendered as Uranus.
In Greek, ouranos means "heaven" but this must not be taken to mean that the gods original function was the personification of the sky.
the association of Ouranos with the sky might have derived from the fact that an earlier name for the god seems to have been Epigeios, that is "the One who is above the earth."
Plato himself referred to Ouranos as Kosmos, concerning which see above.
It was, however, the Phoenician Sanchoniathon who directly equated Ouranos with Kronos/Saturn.
