Question

What does "over a withered moor" means?

Answer 1

Moorland ( as found in Yorkshire for instance - see Jayne Eyre etc) is usually covered in heather and tuft grass. The stuff is very hardy and survives most extemes of weather - likes it wet and damp - but the plants will wither and die if allowed to get dry ( hot & sunny).

Withered moor - dried out plants on the moorland.

Answer 2

During the Middle Ages, "Moor" was a common term to refer to the Muslims of the Islamic Iberian Peninsula and North Africa, so "over a withered moor" may refer to some kind of leap-frog competition involving an elderly one, I suppose.

Answer 3

A moor is a field or a bog. I think a wilted moor suggests decay or withering away.
