The zodiac consists of three concentric zones, whose boundaries are marked, as is also the centre point. The outermost zone carries the signes, represented in the usual fashion. In the middle zone is a snake which Vermaseren identifies with the constellation of Draco […]. In the inmost zone are two bears which represent — the identification is here indisputable — the constellations Ursa Major and Ursa Minor. Lastly, outside the outermost ring are two figures which probably represent wind-gods, one of which is blowing on a long horn.
