In literature the symbolism "Horse" & "Moon" what does it mean?"?

You need to give the context. Author, title, date, etc.

I'll give you an example. The first big reference to horses in the bible is the four horsemen of the apocalypse. The Jews rode asses. They had no interest in horses probably because of economics and climate. The Romans had horses and so did the Chinese. When John wrote Revelation and mentioned horses, he told educated readers a whole lot about himself and the period he was writing in. The same goes for camels in the old testament. The stories were added hundreds of years after camels were imported to the holy land; they were not indigenous to Palestine.

Here's another example. Both east and west use the word Dragon for a mythical creature. In the east, it is benign and in the west it is destructive. Asking about dragons symbolism is meaningless until you tell us east or west.

"freedom/power"

"female/power"
