The Last Supper at San Salvi. Thanks to Andrea del Sarto for the inspiration.
Though highly regarded during his lifetime as an artist 'without errors', his renown was eclipsed after his death by that of his contemporaries - Leonardo da Vinci, Michelangelo and Rafael. However this beautiful work remains, is freely accessible and oftentimes there is no-one else there to impede the view. A perfect start to Sunday. :)
