Sienese painting in the fifteenth century is distinguished by its mystical tone and its exceedingly conservative, not to say retrogressive, spirit. No preoccupation with scientific researches, no problems of movement or anatomy, disturbed the calm of the Sienese painters; we meet with hardly any portraiture in their work, and even less mythology. These most turbulent of Italian people who, in De Commines’ famous phrase, “are ever in division, and govern their commonwealth more fondly than any other town in Italy,” chose that their painters should give them art that was exclusively the handmaid of religion. While foreign sculptors, such as Donatello and Ghiberti, were welcomed and employed in Siena, foreign painters were practically excluded until the last two decades of the century. Great spiritual beauty in faces, accuracy of drawing within certain limits, with a profusion and a lavishness in the use of gold and the most brilliant colours (this the Sienese particularly demanded of their painters), characterise the school at this epoch. Their strength and their weakness alike are shown in that their most typical painter is styled the “Sienese Fra Angelico,” while there never was, at least to any good effect, a Sienese Masaccio. The chief painters whose work falls into this period are: Sano di Pietro (1406-1481), Domenico di Bartolo (whose few extant works are dated from 1433 to 1443), Giovanni di Paolo (died in 1482), the sculptor Lorenzo di Pietro, called Il Vecchietta (1412-1480), Stefano di Giovanni called Sassetta (died in 1450). And then, following after these, a second group: Matteo di Giovanni, who was born about 1435 and died in 1495; Francesco di Giorgio Martini (1439-1502), Neroccio di Bartolommeo Landi (1447-1500), Benvenuto di Giovanni (1436-1518)—these three the pupils of Lorenzo di Pietro.
These painters and their contemporaries are represented in the four following rooms of the gallery. In Stanza III., a curious little panel by Domenico di Bartolo (19), with a devout inscription in honour of the Madonna, signed Dominicus and dated 1433, contrasts strongly with the more typical Sienese works that surround it. The composition, the types of Angels, the naked Child, all show ill-assimilated Florentine influences. The Child in its unidealised humanity is the first nude infant in Sienese art; all Sano’s babes, for instance, are more or less clothed, already dreaming divine dreams. Domenico was a native of Asciano who came to Siena, and is said to have become the pupil of Taddeo di Bartolo; all his work, however, is a kind of protest against the mystical Sienese tradition in painting. Certain great frescoes of his, which we shall see later in the Spedale, stand alone in the story of the art of Siena. Then follow some small pictures by Sassetta (21 to 24), fairly representative. Giovanni di Paolo—a prolific and always agreeable, if somewhat monotonous and weak painter—is more fully represented here, in a series of Madonnas and Saints, scriptural scenes and mediaeval legends. Two of his pictures (28 and 55) are signed and dated 1453 and 1440 respectively. His Last Judgment (27), the predella of a picture painted for San Domenico in 1445, is particularly interesting; much of it is the usual tradition, but the Paradiso on our left is full of most poetical and fanciful details, slightly reminding us of Angelico’s work in the Florentine Academy, but conceived in a curiously different spirit. The scenes from the life of St Galganus (53) are a favourable example of his ingenuous narrative power. When Il Vecchietta turns from sculpture to painting, he lays aside his science and follows the Sienese tradition with the rest. His San Bernardino (63) has considerable interest, being to all intents and purposes a contemporary portrait. A large altarpiece, badly preserved (67), is one of the works that he painted as an offering for the church of the Spedale, and is signed: “The work of Laurentius Petri, sculptor, alias El Vecchietta, for his devotion.” The shrine, painted on both sides with figures of Andrea Gallerani and other Sienese saints, comes from the same place. We may notice the Madonna and Child with St Francis and St Dominic (66), by Pier Francesco Fiorentino, a Florentine priest who painted in the latter part of the fifteenth century, and who shows himself as reactionary as any master of Siena; his works abound at San Gimignano and throughout the Val d’Elsa. Mr Berenson ascribes to him the four little trionfi at the other end of the present room—the Triumphs of Death, Chastity, Love and Fame (4 to 7), partly after Petrarch—which were at one time erroneously attributed to Andrea di Vanni.
The next two rooms, Stanza IV. and Stanza V., are entirely devoted to Sano di Pietro. Sano, or Ansano, is the most mystical, the most genuinely inspired by religious devotion, of all the painters of Siena; like Fra Angelico, his life was in perfect harmony with his art, pictor famosus et homo totus deditus Deo—so is he described in the document that registers his death—“a famous painter and a man utterly dedicated to God”; but, unlike Angelico, he was a married man and a father of children. In these two rooms he can be thoroughly studied in all his phases. His brush moves in a somewhat restricted field. It is always the Madonna with her Divine Child, surrounded by saints and adored by Seraphim, now listening to the music of attendant Angels, now crowned by her Son with the diadem of Paradise. Or we have saints, men and women, rapt in ecstasy and already of another world. Sometimes monks or nuns are introduced, kneeling at Our Lady’s feet or worshipping her Child, or the portrait of the donor—frequently (as in number 9 of Stanza IV.) some devout nun who had it painted “for the soul of her father and of her mother”; but such figures are always very small indeed, as though to reduce the human element to a minimum. The faces are always very sweet—the Angels, with the flame of the Holy Spirit resting upon their foreheads, perhaps especially so—the colours are of that almost shadowless brightness that the Sienese loved. Among the Sienese saints introduced we may notice (Stanza IV., 25) the founder of the Gesuati, the Beato Giovanni Colombini, kneeling at the Madonna’s feet; he was a leader in the religious life of Tuscany when St Catherine was a child, and the Colombini were connected by marriage with the Benincasa.
One picture in Stanza IV. (20) is unique among Sano’s works, and may be described as a mystical treatment of contemporary history. Pope Calixtus III. is enthroned in full pontifical robes, his cope being buckled with the Borgia arms, while below appears Siena with the Tower of the Palazzo and the Campanile of the Duomo; mules are being driven into the city, laden with sacks of grain marked with the balzana, the muleteer being armed and looking round in fear to see if he is pursued. In the clouds the Madonna appears, to commend her city to the Holy Father, a scroll bearing her words: “O worthy Pastor to my Christian people, to thee henceforth do I render the care of Siena; to her let all thy kindly feeling turn.” And we have his answer: “Virgin Mother, dear Consort to God, if thy Calixtus is worthy of so great a gift, nought save death shall sever me from Siena.” Though somewhat hastily painted, and though the character of Calixtus is hardly more realised than in the case of Giotto’s popes, the historical interest of the picture, which was executed for the Palazzo Pubblico, is considerable. In 1455, when Piccinino the great condottiere—in secret understanding with Giberto da Correggio, the commander of the Sienese forces, and with Ghino di Pietro Bellanti and other traitors within the walls—was preparing to make war upon the Republic, Calixtus (Alfonso Borgia), then newly-elected Pope, took Siena under his protection and sent the ecclesiastical forces to its support. He urged the Sienese to prosecute the war to the bitter end, declared that their cause was his own. “We shall maintain inviolate your own and the common peace and quiet of all Italy,” he said to the Captain of the People and the Priors of the Commune in a bull dated August 14th, 1455, “even to the shedding of our own blood, if needs be.” “You have a Pope,” wrote Enea Silvio Piccolomini (who was not yet Cardinal), a few days later to the Balìa, “most affectionate towards
your Republic, as you perceive; know how to take advantage of it, for his courage is as great as his charity, nor has he anything at heart save justice.”[64] When the Balìa wanted to compromise and make peace, Calixtus would not hear of it, but sent abundant grain and provisions into the hungry city. This is the situation represented in the picture, which may confidently be dated 1455; but a comparison with the Pope’s medals shows that Sano has hardly done justice to the rather striking features of the first Pope of the House of Borgia.
There is an analogous picture by Sano in Stanza V., San Bernardino (2) as champion of the devotion of the Holy Name, as the inscription, “I have manifested Thy Name to men,” indicates. Painted in 1460, sixteen years after the Saint’s death, it is less a contemporary portrait than that by Lorenzo di Pietro. All the other pictures in this room are in Sano’s usual mystical style. There is an interval of thirty years between the date of the Madonna of San Biagio (4), the saintly Bishop whose miracles and martyrdom are so quaintly depicted in the predella, and that of the Assumption (8, 9); but there is little, if any, advance in technique or development in style. But no sympathetic student of Sienese painting can ever find Sano di Pietro monotonous, or otherwise than fascinating.
