The calisson is believed to have its origins in south of France. Its most probable etymology, established by the sociolinguist specializing in Provençal Philippe Blanchet in 1998, is that the Provençal word
calissoun is formed from "
chalice" and from the diminutive "
-oun", meaning "
small chalice". Small in size and small in sacred value. The word "
chalice", in fact, in
Provençal as in
French (we have the form "
calitz" from the ancient
langue d'oc), first designated the sacred cup of the Eucharist, and by extension communion itself. Now communion is wine and the host, distributed in a cup. And the calisson is, ritually, a kind of host. A popular legend traces the introduction of calissons to
Provence around the mid-15th century at the second wedding of King
René of Anjou. Others suggest that it was not introduced in its modern form until the 16th century, as this was when almonds became an established crop in
Aix-en-Provence. ==Protected Geographical Indication (PGI)==
