The analogy of style observable in the figures impressed on Tuscan coins of the tenth, eleventh, and twelfth century, and those found in the miniatures that decorate the manuscripts of the contemporary periods, proves that Tuscany had its artists long before the epoch which Vasari and his copyists fix for the importation of Greek art with Greek artists: whether those paintings be all pure Tuscan, or here and there interspersed with Greek ones, none will venture to decide, who knows the impossibility of drawing a limitary line sufficiently severe to distinguish the last spasms of an expiring art from the first stammerings of an infant one. Of the still surviving monuments of painting during those epochs, it may be sufficient to mention the famed Christ, painted on canvass and glued to a wooden cross, of a date anterior to 1003. In subsequent times, the earliest and least unsuccessful essays in art, were made by the Pisano. Whilst a Greek sarcophagus at Pisa, storied with the incidents of Hippolytus and Phædra, furnished some elements of form to the sculptors Niccolo and Giovanni Pisano, painting made some progress with Giunta Pisano: his composition of Christ on the Cross at the Angeli of Assisi, though defective in design, possesses life and expression.[44] A similar progress was made by his contemporary Guido or Guidone of Sienna; a name not mentioned by Vasari, though in his frequent excursions to Sienna, he could not remain unacquainted with the works of Guido, at least one which still exists in the chapel of the Malevolti in S. Dominico, with the following often repeated inscription and date:-- Me Guido de senis diebus depinxit amenis Quem Christus lenis nullis velit agere penis. A.D. M.CCXXI. This Madonna, twenty years anterior to the birth of Cimabue, is superior to his Madonna in expression, and nearly equal in taste and colour, though inferior in style.
