I was reading through the Donum Dei text yesterday and noticed the order of the elements was

"The first is winter cold and moist, the second is ver, hot and moist, and flourishing. The third is the summer time, hot and dry, and red. The fourth is the harvest cold and dry, which is the time of gathering of fruit."

Notice the rotation of elements is given as Water > Air > Fire > Earth

Mostly the elements are given from their grossest to their Subtlest:

Earth > Water > Air > Fire

First I thought it was a mistake but then thinking further on this thought that it may be possible to rotate through the phases in a different order and still have success.
