SLIDESHOW - Collection of artworks – quince in Art. Plutarch reported that a Greek bride would nibble a quince to perfume her kiss before entering the bridal chamber, "in order that the first greeting may not be disagreeable nor unpleasant". It was with a quince that Paris awarded Aphrodite. It was for a golden quince that Atalanta paused in her race. The Romans also used quinces; the Roman cookbook of Apicius gives recipes for stewing quince with honey, and even combining them, unexpectedly, with leeks. Pliny the Elder mentioned the one variety, Mulvian quince, that could be eaten raw. Columella mentioned three, one of which, the "golden apple" that may have been the paradisal fruit in the Garden of the Hesperides, has donated its name in Italian to the tomato, pomodoro.
