That vertue haue, or this, or that to make,
Is checkt and changed from his nature trew,
By others opposition or obliquid view.
Besides, the sundry motions of your Spheares, lv
So sundry waies and fashions as clerkes faine,
Some in short space, and some in longer yeares;
What is the same but alteration plaine?
Onely the starrie skie doth still remaine:
Yet do the Starres and Signes therein still moue,
And euen it self is mov’d, as wizards saine[632].
