Giotto
There are few modern painters who are not greater technically than Giotto, but I cannot call to mind a single one whose work impresses me as profoundly as his does. How is it that our so greatly better should be so greatly worse—that the farther we go beyond him the higher he stands above us? Time no doubt has much to do with it, for, great as Giotto was, there are painters of to-day not less so, if they only dared express themselves as frankly and unaffectedly as he did.
