After this rapid sketch of the influences which modified in a general way the pictures of the Madonna, we may array before us, and learn to compare, the types which distinguished in a more particular manner the separate schools, caught from some more local or individual impulses. Thus we have the stern, awful quietude of the old Mosaics; the hard lifelessness of the degenerate Greek; the pensive sentiment of the Siena, and stately elegance of the Florentine Madonnas; the intellectual Milanese, with their large foreheads and thoughtful eyes; the tender, refined mysticism of the Umbrian; the sumptuous loveliness of the Venetian; the quaint, characteristic simplicity of the early German, so stamped with their nationality, that I never looked round me in a room full of German girls without thinking of Albert Durer's Virgins; the intense life-like feeling of the Spanish; the prosaic, portrait-like nature of the Flemish schools, and so on. But here an obvious question suggests itself. In the midst of all this diversity, these ever-changing influences, was there no characteristic type universally accepted, suggested by common religious associations, if not defined by ecclesiastical authority, to which the artist was bound to conform? How is it that the impersonation of the Virgin fluctuated, not only with the fluctuating tendencies of successive ages, but even with the caprices of the individual artist? This leads us back to reconsider the sources from which the artist drew his inspiration. The legend which represents St. Luke the Evangelist as a painter appears to be of Eastern origin, and quite unknown in Western Europe before the first crusade. It crept in then, and was accepted with many other oriental superstitions and traditions. It may have originated in the real existence of a Greek painter named Luca--a saint, too, he may have been; for the Greeks have a whole calendar of canonized artists,--painters, poets, and musicians; and this Greek San Luca may have been a painter of those Madonnas imported from the ateliers of Mount Athos into the West by merchants and pilgrims; and the West, which knew but of one St. Luke, may have easily confounded the painter and the evangelist.
