Calderon’s heroic comedies are much diversified in their kind, and very unequal in their merits. Some are distinguished from the dramas of intrigue only by the rank of the characters. Of this kind is the well known piece, entitled, _El Secreto a Voces_, (the Published Secret), imitations of which have appeared in the Italian, French, and German languages. The Spaniards number it among their heroic comedies, merely because an Italian prince and princess are introduced in it. Other plays by Calderon, which, according to the Spanish nomenclature, are ranked in the heroic class, are in fact romantic pastoral dramas; as for example, the pleasing piece, entitled, _Eco y Narciso_. Others again are romantic, mythological festival pieces, accompanied by transformations and melo-dramatic splendour; of this kind is _El mayor encanto Amor_, (Love is the greatest Enchantment). Finally, among Calderon’s heroic comedies are included his historical dramas, several of which may properly be called tragedies. Some of these historical dramas are among the best, while others are the most trivial of Calderon’s productions. All are melo-dramatic spectacles, in which armies defile, battles are fought, and sumptuous banquets are given. The scene is, by turns, a palace, a vast landscape, a cavern, or a pleasure garden, while drums and trumpets flourish, and cannon thunder at every opportunity. In all that regards scenic splendour in the composition of historical plays, even Lope de Vega must yield to Calderon, for the dramas of the latter were represented at the expence of the royal treasury. But in the historical style of dramatic composition Calderon only succeeded when he selected his materials from the events of his own country. Where he has adapted to the Spanish stage, subjects from the Greek and Roman history, as in his Alexander the Great,[545] and in his Coriolanus,[546] the absurd change of costume is almost forgotten amidst the extravagant confusion of the events, by which romantic situations are brought about one after another, but which, on the whole, produce only a mean effect. The great poet seems occasionally to have been forsaken by his good genius, particularly when he makes a display of his erudition in the very same scenes in which he completely perverts ancient history. But Calderon’s historical dramas of this class are very inferior to those of which the story was invented by himself, and the scene arbitrarily laid in ancient Greece. Among the latter is a piece, entitled, _Finezas contra Finezas_, (Generosity for Generosity), a beautiful poem, full of tenderness and mythological piety. But this drama, though, perhaps, single in its kind, must nevertheless yield to the christian drama, of which the history of Portugal furnishes the hero. The tragedy of Don Fernando, entitled, _El Principe Constante_, displays all the lustre of Calderon’s genius. The unities of time and place are lost sight of in the unity of the
