The third and fourth parts showed Useful and Necessary Curiosity, respectively. Useful Curiosity was represented by travellers whose desire to learn all about the manners and customs of different nations drove them into foreign countries; also “by physicians who work to gain experience.” In Necessary Curiosity was introduced the art of navigation, instanced by sailors, who, under the guidance of Tiphys, helmsman of the _Argo_, set out “to discover new worlds”; another example of “necessary curiosity” being the fire brought from Heaven by Prometheus for people eager to discover its use. The poetical allegories were not less ingenious than the philosophic, although “they did not pretend,” as one old chronicler informs us, “to so much precision.” In the same year at the Savoy Court, “_Alcée_,” a ballet of fishermen, with _intermezzi_ and some superb presents brought to Mme. Royale for her birthday by the Prince of Piedmont and his Cavaliers, was a grand water entertainment in which appeared, to quote an old historian, “Le Vaisseau de la Felicité accompagné de toutes les Deitez (sic) avec les Concerts de Musique, des quatres Elemens avec leur machines; de la Representation en Music (sic), d’Arion, du Temps avec les années heureuses, des quatres parties du monde avec des Entrées de Ballets, des quatres Saisons avec le tribut de toutes leurs douceurs pour le Festin.” This was given by the Duke in honour of Mme. Royale on her birthday, and it was declared that a fête “plus complette, plus magnifique et plus agréable” had never been seen. “Eternity” was the title of a ballet given in 1629; “Le Temps Eternel” following next year; “La Felicité Publique” the next; and in 1632, “La Chasse Theatrale, representée en Ballet,” by the Cardinal of Savoy at his country mansion was given in honour of his brother, the Duke’s birthday. Among the “moral” ballets, there is hardly one more pleasing than that composed to commemorate the birthday of the Cardinal of Savoy in 1634. The subject of this ballet was “Truth, the Enemy of Appearance, as proved by Time”--_La Verita Nemica della Apparenza sollevata dal Tempo_. This ballet opened with a chorus of False Rumours and Suspicions, followed by Appearance and Lies! They were curiously represented by characters dressed as cocks and hens, who sang a dialogue half in Italian and half in French, mingled with the cluckings of cocks and hens. The chorus by the latter ran as follows: “Su gli albori matutini Cot, cot, cot, cot, cot cantando Col cucurrii s’inchini E bisbigli mormorando Fra i sospetti, e fra i Rumori Cu, cu, cu, cu, cu, cu, cu, Salutiam del novo sol gli almi splendori.” The cocks replied:
