"No one knows the gods."

Translation: Nemo deos scit.

[CatharinaA544571]

When you want to say that you know someone, you should say "novi" instead of "scio". Exempli gratia: Nemo deos novit.

[SuzanneNussbaum]

Ita vērō, or also, I think, Nēmō deōs cognōvit.

[ClausFenge]

In many languages, say German or French, you have to distinguish between kennen/connaître and wissen/savoir. In Latin, it would be cognosco v scio. Everybody 'knows' the gods (scio), i.e., what they are called and what they represent, but nobody 'knows' the gods (cognosco), i.e., can predict what they will do.

Actually, "scire alqm" was used, from 2nd century AD onwards, in the sense "kennen jmd.", see http://www.zeno.org/Georges-1913/A/scio?hl=scio (II-B).

That's interesting to know; thank you.

[GaiusSolitaire]

The second one is actually "novi", but the rest is right.
