The poem
XXXVII
Pardon, oh, pardon, that my soul should make, Of all that strong divineness which I know For thine and thee, an image only so Formed of the sand, and fit to shift and break. It is that distant years which did not take Thy sovranty, recoiling with a blow, Have forced my swimming brain to undergo Their doubt and dread, and blindly to forsake Thy purity of likeness and distort Thy worthiest love to a worthless counterfeit: As if a shipwrecked Pagan, safe in port, His guardian sea-god to commemorate, Should set a sculptured porpoise, gills a-snort And vibrant tail, within the temple-gate.
