The essays of Masaccio in imitation and expression, Andrea Mantegna[29] attempted to unite with form; led by the contemplation of the antique, fragments of which he ambitiously scattered over his works: though a Lombard, and born prior to the discovery of the best ancient statues, he seems to have been acquainted with a variety of characters, from forms that remind us of the Apollo, Mercury or Meleager, down to the fauns and satyrs: but his taste was too crude, his fancy too grotesque, and his comprehension too weak to advert from the parts that remained to the whole that inspired them: hence in his figures of dignity or beauty we see not only the meagre forms of common models, but even their defects tacked to ideal Torsos; and his fauns and satyrs, instead of native luxuriance of growth and the sportive appendages of mixed being, are decorated with heraldic excrescences and arabesque absurdity. His triumphs are known to you all; they are a copious inventory of classic lumber, swept together with more industry than taste, but full of valuable materials. Of expression he was not ignorant: his burial of Christ furnished Raphael with the composition, and some of the features and attitudes in his picture on the same subject in the palace of the Borgheses,--the figure of St. John, however, left out by Raphael, proves that Mantegna sometimes mistook grimace for the highest degree of grief. His oil-pictures exhibit little more than the elaborate anguish of missal-painting; his frescoes, destroyed at the construction of the Clementine museum, had freshness, freedom, and imitation. To Luca Signorelli, of Cortona,[30] nature more than atoned for the want of those advantages which the study of the antique had offered to Andrea Mantegna. He seems to have been the first who contemplated with a discriminating eye his object, saw what was accident and what essential; balanced light and shade, and decided the motion of his figures. He foreshortened with equal boldness and intelligence, and thence it is, probably, that Vasari fancies to have discovered in the last judgment of Michael Angelo traces of imitation from the Lunetta, painted by Luca, in the church of the Madonna, at Orvieto; but the powers which animated him there, and before at Arezzo, are no longer visible in the Gothic medley with which he filled two compartments in the chapel of Sixtus IV. at Rome.
