Then first he form’d the immense and solid shield; Rich various artifice emblazed the field; Its utmost verge a threefold circle bound;[253] A silver chain suspends the massy round; Five ample plates the broad expanse compose, And godlike labours on the surface rose. There shone the image of the master-mind: There earth, there heaven, there ocean he design’d; The unwearied sun, the moon completely round; The starry lights that heaven’s high convex crown’d; The Pleiads, Hyads, with the northern team; And great Orion’s more refulgent beam; To which, around the axle of the sky, The Bear, revolving, points his golden eye, Still shines exalted on the ethereal plain, Nor bathes his blazing forehead in the main.
