The road from the Mona Lisa to joconde sponge cake is a slightly circuitous one, but it goes like this: the portrait of the Mona Lisa was commissioned by a fellow by the name of Francesco di Bartholommeo di Zanobi del Giocondo, a wealthy silk merchant who lived in Florence around the turn of the Sixteenth Century. He commissioned the painting — a portrait of his wife, a commoner by the name of Lisa Gherardini — to commemorate the birth of their second son, Andrea.
The artist, one Leonardo da Vinci, accepted the commission and spent some four years working on and/of fiddling with it. In the end da Vinci became so attached to the painting that he never delivered it, and ultimately took it with him to France when he moved there around 1515. There he sold it to the King of France and it’s been property of the French government ever since.
But now where was I? Oh yes, the name thing. It just so happens that the surname of the man who originally commissioned the painting, Giocondo, is very similar to another Italian word, gioconda which means “cheerful” or “merry” (like the English word jocund). Thus the name of the Mona Lisa is something of a pun there: la Giocanda. The French, likewise fans of word play, refer to the painting in the same way, only using their equivalent word, joconde. La Joconde is thus a double entendre, if you follow me.
Of course in both countries the painting is also known by its more proper name Monna Lisa (monna being a contraction if the words ma donna which mean “my lady” in Italian). How the word got to be applied to an almond sponge cake is less clear. As yet I’ve found no documentation as to how or why it may have happened. To my way of seeing things, it’s just as likely that joconde could mean “merry” cake as it could “Mona Lisa” cake. Though it probably is meant to mean both. Oh those punny, punny Continentals.
name Joconde is also a port-manteau word, comprising two words: joc (Catalan name to a social game, social play) and onde (French name to a wave, high wave, swell, vogue). Me and my sibling families do researches, criptanalysis and criptologies. Jelly Roll, Swiss Roll, Ruse Roulade, in this sense, also have to do with famous artworks, specifically JeanDelVille’s “Love of Souls”.
