After the days of Duccio and Simone Martini, of Ambrogio and Pietro Lorenzetti, were over, there remained but little for the Sienese to do in painting. Taddeo di Bartolo continued the tradition of Duccio as the later Giottesques continued that of Giotto. His most remarkable wall-painting is a fresco of the Apostles visiting the Virgin, the motive of which is marked by great originality.[155] Our Lady is seated in an open loggia with a company of holy men and women round her. Descending from the sky and floating through the arches are three of the Apostles, while one who has just alighted from his aërial transit kneels and folds his hands in adoration. Seldom have the longing and the peace of loving worship been more poetically expressed than here. The seated, kneeling, standing, and flying figures are admirably grouped together; their draperies are dignified and massive; and the architectural accessories help the composition by dividing it into three balanced sections. Such power of depicting movement was rare in the fourteenth century. To find its analogue, we must betake ourselves to the frescoes of Spinello Aretino, a master more decidedly Giottesque than his contemporary Taddeo di Bartolo.[156] A Gabriel, rushing down from heaven to salute Madonna, with all the whirr of arch-angelic pinions and the glory of Paradise around him, is a fine specimen of Spinello's vehemence. The same quality, more tempered, is noticeable in his frescoes of the legend of S. Ephesus at Pisa.[157] Few faces in the paintings of any period are more fascinating than the profiles under steel-blue battle-caps of that godlike pair--the knightly saint and the Archangel Michael--breaking by the irresistible force of their onset and their calm youthful beauty through the mailed ranks of the Sardinian pagans. Spinello was essentially a warlike painter; among the best of his compositions may be named the series of pictures from the history of the Venetian campaign against Frederick Barbarossa.[158] It is a pity that the war of liberation carried on by the Lombard communes with the Empire should have left but little trace on Italian art; and therefore these paintings of Spinello, in addition to their intrinsic merit, have rare historical interest. Delighting in the gleam of armour and the shock of speared warriors, Spinello communicated something of this fiery spirit even to his saints. The monks of Samminiato near Florence employed him in 1388 to paint their newly-finished sacristy with the legend of S. Benedict. In the execution of this task Spinello displayed his usual grandeur and vigour, treating the grey-robed brethren of Monte Cassino like veritable champions of a militant Church. When he died in 1410, it might have been truly said that the flame of the torch kindled by Giotto was at last extinguished.
