How to breed Olympus dragons on dragonvale

I just got on dragonvale today and there were three new rare dragons, bronze Olympus, silver Olympus, and gold Olympus. They look strange but they are rather new so I just wanted to know if anybody was able to breed them.

Solution 1:

While there are three types of Olympus Dragons, all three seem to be the same combination of elements: Air, Earth, Lightning and Fire. This makes -many- different dragon combinations possible as long as they posses those four elements.

When properly bred all three types appear to have the same breeding time for 35 hours.

This information was taken from the appropriate wiki pages for the Bronze, Silver and Gold versions of the Olympus dragons.
