"The 'Caprices' of Thomas move in a higher circle than Wenzel's 'Adieu de St. Petersbourg,' but, notwithstanding the evident application and the great amount of talent evinced, are nothing more nor less than higher-class Wenzel; 'lederne' German thoughts translated into the French language, so pleasant that one must needs beware of them, and so pretentious that one could well get vexed with them. Occasionally the composer wanders into mystic harmonies, but, soon frightened at his own temerity, returns to his natural mode of expression, to what he possesses and is able to give. But what do I expect? The 'Caprices' are pretty, sound well," etc. During his sojourn in the eternal city, Thomas made himself popular with all who came across him, and was alluded to by Ingres, the celebrated painter, at that time head of the school whither were sent the successful young artists and musicians who had won the "Prix de Rome," as "l'excellent jeune homme, le bon Thomas." The operatic career of the composer of "Mignon" dates from the year 1837, his first venture being a one-act comic opera entitled "La Double Échelle," produced at the Opéra Comique. This was succeeded the following year by "Le Perruquier de la Régence," three acts, at the same theatre; and in 1839 by "La Gipsy," a ballet at the Opéra, in collaboration with Benoist, and "Le Panier Fleuri," at the Opéra Comique. The prolific nature of the composer's talent was further illustrated by the production in quick succession of "Carline" (1840), "Le Comte de Carmagnole" (1841), "Le Guerillero" (1842), and "Angélique et Médor" (1843), none of which obtained any appreciable success. It was otherwise with "Mina," a three-act comic opera, produced at the Opéra Comique in 1843, which enjoyed a certain vogue at the time, but has not survived. The first permanent success achieved by Thomas was with "Le Caïd," a light opera given in 1849, which rapidly became popular, and is regarded by some as the precursor of the style of _opéra bouffe_ which was destined later on to achieve so great a notoriety at the hands of Offenbach and his imitators. This is scarcely a correct view to take, as the innate refinement of a nature such as that of Ambroise Thomas has little in common with the vulgarities associated with the _genre_. "Le Caïd," in which the composer amusingly parodies the absurdities associated with the now happily obsolete Italian opera style of the period, would nowadays pass muster as a high-class _opérette_. This bright little score is full of that _esprit_ of which French composers seem to possess the secret, and is wedded to an exceedingly amusing libretto. "Le Caïd" has remained popular in France, and occupies a permanent place in the _répertoire_ of the Paris Opéra Comique.
