Jewelry from the time when people knew how to eat medlars.
Mentioned in Shakespeare's Romeo and Juliet as well as in Miguel de Cervantes' Don Quixote, the medlar is a large shrub or small tree and also the name of the fruit of this tree. The fruit has been cultivated since Roman times, is usually available in winter, and is eaten when bletted. It was a very important fruit during the Roman Empire and Middle Ages before the introduction of other fruits in Western Europe. During the Middle Ages, it was planted mainly in monastery gardens.
In our days, medlars can occasionally be found at specialised markets and greengrocers... and in the Garden of Adin, of course, together with other beauties from the old days.
