Well, yeah. There are "philosophers" that claim the turtle walks on the bottom of the crystal sphere in which the Sun, Moon, planets and stars are embedded. Like a giant hamster wheel, this causes the sphere to rotate around the Earth and accounts for the rising and setting of the above objects.
Of course we know that such "philosophers" are heretics. It's definitely turtles all the way down.
It may be turtles all the way down, but each turtle moves in its own proper epicycle.
