The Temple of Vesta at Tivoli dates from circa 80 BC and is circular peripteral, set on a podium which supports a cella 24 feet in diameter. The peristyle is composed of eighteen Corinthian columns, 23.5 feet (or 9.7 diameters) in height. The capitals which have a large flower at the centre are based on a crinkled form of Acanthus Mollis. Piranesi depicted it three times from 1762 as part of a major deliniation of Tivoli and these depictions were included under the title 'The Temple of the Sybil' in the Vedute di Roma. It has been regarded as the most picturesque and is among the most painted of all the ruins of Italy, this accounting for Ruskin 's reference here.
