Sir Samuel Ferguson - "Paul, let thy faces from the canvas look" lyrics

Paul, let thy faces from the canvas look Haply less clearly than Pietro's can, Less lively than in tints of Titian, Or him who both the bay-wreath-chaplets took: Yet shalt thou therefore have no harsh rebuke Of me whom, while with eager eye I scan O'er painted pomps of Brera and Vatican, The first delight thou gavest ne'er forsook. For in thy own Verona, long ago, Before one masterpiece of cool arcades, I made a friend; and such a friend was rare. For him, I love thy velvet's glorious show, Thy sheens of silk 'twixt marble balustrades, Thy breathing-space and full translucent air.
