About this time other able artists flourished at Florence, who were obscured by greater names. Of this number was Berto Linaiuolo, whose pictures in private houses were, for a long time, held in great repute. They were even ordered by the King of Hungary, and procured him great fame in that kingdom. Alessio Baldovinetti, of noble extraction, was a painter particularly diligent and minute, a good worker in mosaic, and the master of Ghirlandaio. In his picture of the Nativity in the porch of the Nunziata, and in his other works, the design, rather than the colouring, may now be said to remain; for the tints have vanished, from a defect in their composition. To them we may add Verrocchio, a celebrated statuary, a good designer, and a painter for amusement rather than by profession. While he painted the Baptism of Christ at S. Salvi, his scholar, L. da Vinci, then a youth, finished an angel, in a manner superior to the figures of his master, who, indignant at his own inferiority to a boy, never more handled the pencil.
Baldinucci imagines that Andrea del Castagno, a name infamous in history, was a scholar of Masaccio: he was rather his imitator, in attitude, relief, and casting of the drapery, than in grace and colouring. He lived at the time that the secret of painting in oil (discovered by John Van Eych, or John of Bruges, about 1410),[73] was known in Italy, not only by report, but by experience of the advantages of this method. Our artists, admiring the harmony, delicacy, and brilliance, which colours received from this discovery, sighed to possess the secret. For this purpose, one Antonello da Messina, who had studied at Rome, travelled to Flanders, and having learned the secret, according to Vasari, from the inventor, went to Venice, where he communicated it to a friend named Domenico. After having practised much in his own country, at Loreto,[74] and other parts of the ecclesiastical states, Domenico came to Florence. There he became the general favourite, and on that account was envied by Castagna, whose dissembled friendship won him to impart the secret, and rewarded him by an atrocious assassination, which he perpetrated, in order that there might be none living to rival him in the art. The assassin was sufficiently skilful to conceal his crime, owing to which a number of innocent persons soon fell under suspicion, which did not induce the real criminal to avow the atrocious deed, until he lay upon his death-bed, when he disclosed his guilt and did justice to the innocence of others. He had the reputation of being the first artist of his time, for vigour, for design, and for perspective, having perfected the art of foreshortening. His finest works have perished: one of his pictures remains at S. Lucia de' Magnuoli, and also some of his historic pieces, executed with great diligence. There is also a Crucifixion, painted on a wall in the monastery of the Angeli.
Many writers have appeared who deny the above mentioned statement of Vasari, and maintain that the art of painting in oil was known long before. It is pretended that it existed in the time of the Romans, an opinion that is adopted by Sig. Ranza, in regard to a picture said to be of S. Helena, consisting of a quilting of different pieces of silk stitched together, exhibiting a picture of the Virgin Saint with the Infant. The heads and hands are coloured in oils; the drapery is shaded with the needle, and in a great measure with the pencil. It is preserved in Vercelli, and from the tradition of its citizens reported by Mabillon (Diar. Ital. Cap. 28), it is said to be the work of S. Helena, mother of Constantine; that is, the patches of silk were sewed by her, and the gilding and painting added to it by her painter, as is conjectured by Ranza. He was not aware that the practice of drawing the Infant Christ in the lap of the Virgin (as we notice in the preface to the Roman school), was posterior to the fourth century; and that other particulars related by him of the picture cannot belong to the age of Constantine; for instance, the hooded mantle of our Lady. From such signs we ought rather to conclude that it is either not an oil painting, or that the figure, at whatever period executed, has been retouched in the same way as that of the Nunziata at Florence, or of the Santa Maria Primerana at Fiesole; the former of which in the drapery, and the latter in the lineaments, are not the same now as in their ancient state.
Others, without ascending to the first ages of the church, have asserted that oil painting was known out of Italy, at least as early as the eleventh century. As a proof of this, they adduce a manuscript of the Monk Teofilo or Ruggiero, no later back than that period, which bears title, "De omni scientiâ artis pingendi," where there is a receipt for the preparation and use of oil from flax.[75] Lessing gave an account of this manuscript in the year 1774, in a treatise published at Brunswick, where he filled the office of librarian to the Prince. Morelli, also, in the Codici Naniani (cod. 39); and more at length Raspe, in his critical "Dissertation on Oil Painting," published in the English language at London, in which he enumerated the existing copies in various libraries, and gave a great part of the manuscript, entered into an examination of the subject. Lastly, Teofilo's treatise is inserted by Christiano Leist, in Lessing's collection, "Zur Geschichte unde Litteratur." Brusw. 1781. The Dottore Aglietti, in his Giornale Veneto, December, 1793, likewise adds his opinion; while the learned Abbate Morelli, in his "Notizia," which is often cited by me in the emendation and illustration of this edition, throws the greatest light upon the present question, agitated by so many, and, we may add, "rem acu tetigit." He, then, will be found to concede to Giovanni, whom he calls Gianes da Brugia, the boast of this great discovery, agreeing with Vasari, though in a different sense from that in which the latter writer views it. For he does not reply to his opponents, that the art of painting, as taught by Teofilo, might have gone into disuse, and was only revived by Giovanni; whence Vasari ventured to commend him as an original inventor; in the same manner as Tiraboschi replied, who followed the Roman anthologists (St. Lett. t. vi. p. 1202). Neither does he bring forward the defence advanced by the Baron de Budberg in the apology of Gio. da Bruges,[76] to the purport that Teofilo taught the art of painting in oil, only upon a ground, without figures, and without ornaments: because Teofilo, in chap. 22, whose words we have given in the note, likewise taught this art. Into what, then, does the long-boasted invention of Giovanni resolve itself? Nothing more than this: according to the ancient practice, a fresh colour was never added to the panel until the first covering had been dried in the sun: a mode, as Teofilo confesses, infinitely tedious: "quod in imaginibus diuturnum et tædiosum nimis est;" (cap. 23); to which I may add, that the colours in this way could never perfectly harmonize.
