I imagine a polar dial made out of a boulder (not marble), say 4 or 5 feet tall, all natural except at the top which is carved (or machined) to a flat surface, parallel to our earth's axis, with either a central gnomon or a pair of gnomons on the sides, also carved out of the rock, of course. I think that would be a very nice design for a public monumental dial. The justaposition of the natural boulder and the polished surfaces at the top would be very satisfying, don't you think? jh
