Zerline is a dealer in oranges, and she lands her cargo, placing it in the market. The original tenants of the place dispute her right to come among them, and are about to expel her by force, when a marine officer, Rodolf, takes her part, and, drawing his sword, puts the whole crowd to flight. Zerline, moved by this instance of heroism, tells him her story, that she was coming "un beau matin" to the city to sell oranges, when a pitiless corsair captured her, and carried her to Africa, separating her from her child, whom she had not seen for fifteen years; that she escaped to Malta, laid in a stock of oranges there;--and thus the events of the day occurred. Rodolf, this young hero, is costumed in a tie-wig with powder, stiff skirts, and the dress of a century ago. What tempted the author to put not merely his hero, but all his court characters, into the costume of Queen Anne, is not easily conceivable, as there is nothing in the story which limits it in point of time. Zerline looks after him with sudden sympathy, says that she heard him sigh, that he must be unhappy, and that, if her daughter lives, he is just the _husband_ for her,--Zerline not having been particular as to marriage herself. She then rambles about the streets, singing, "Achetez mes belles oranges, Des fruits divins, des fruits exquis; Des oranges comme les anges N'en _goutent pas en Paradis_." After this "hommage aux oranges!" to the discredit of Paradise, on which turns the plot of the play, a succession of maids of honour appear, clad in the same unfortunate livery of fardingales, enormous flat hats, powdered wigs, and stomachers. The Princess follows them, apparently armed by her costume against all the assaults of Cupid. But she, too, has an "affaire du cœur" upon her hands. In fact, from the Orangewoman up to the Throne, Cupid is the Lord of Palermo, with its "beau ciel, plaine fertile." The object of the Princess's love is the Marquis de Buttura, the suitor of her husband's supposed niece. Here is a complication! The enamoured wife receives a billet-doux from the suitor, proposing a meeting on his return from hunting. She tears the billet for the purpose of concealment, and in her emotion drops the fragments on the floor. That billet performs all important part in the end. The enamoured lady buys an orange, and gives a gold piece for it. Zerline, not accustomed to be so well paid for her fruit, begins to suspect this outrageous liberality; and having had experience in these matters, picks up the fragments of the letter, and gets into the whole secret.
