"At the horizon" or "on the horizon"?

Question

What's the right preposition to use with "horizon"?

Example:

A cruiser cut through waves at the horizon.
A cruiser cut through waves on the horizon.

I get both results on Google: waves on the horizon/waves at the horizon.

So I'm not very sure which version to use.

Answer 1

Go with "on". In my experience it's by far the more common option. Particularly since, when you think of it, the "horizon" is not really a place you can be at.
