The poetic works of Bartholemè, the younger Leonardo de Argensola, which have been preserved, are twice as numerous as those of Lupercio. The style of the two brothers is so similar, that in some cases it is difficult, and in others totally impossible to distinguish the one from the other. This extraordinary conformity of character, talent and taste, appears at first sight no less singular a phenomenon than the inexhaustible fertility of Lope de Vega. But it will be recollected, that these brothers, who were nearly of an age, and almost inseparable companions, and who were constantly occupied in the study and imitation of the same models, could not fail, by the cultivation of similar, and in neither original talents, closely to approximate. Still, however, traces of difference are discoverable in their works. Bartholemè, by his numerous epistles and satires, performed greater services to Spanish poetry than his brother Lupercio. He was the first Spanish writer who introduced concentrated satire in sonnets, which he probably did after he became acquainted with the Italian poems of that class, but he has imitated them with the spirit of Horace, and has avoided every thing like Italian flippancy. His spiritual canciones, which are not equalled by any in the poetic works of Lupercio, are among the best in the style to which they belong. His most esteemed works bear the impress of a more cultivated talent than is discernible in the writings of his brother. His longer and properly didactic satires are characterized by more causticity than gaiety in the ridicule of general and particular follies.[403] But the enthusiasm of the moralist never leads him into declamation in the manner of Juvenal; and these satires are equally replete with traits of mild philanthropy and sound judgment. His epistles on human felicity and human weakness have nearly the same character, but they are for the most part serious and devoid of irony.[404] His satirical sonnets present unequal degrees of merit; but in the best, the pupil of Horace is more obviously recognisable.[405] That Bartholemè should have succeeded in spiritual canciones, may at first sight be deemed a psychological enigma. But it was precisely his critical and reflective turn of mind which proved most essentially serviceable in guiding him through the gloomy regions of catholic mysticism. Being an enthusiastic catholic, he wanted no extraordinary inspiration to furnish him with religious ideas; and the faculties of a language eminently picturesque, supplied him with new views and images which he alternately developed in majestic descriptions,[406] and pleasing comparisons.[407]
