[20] See Dante, _Inferno_ xxix. 121. There was, moreover, in Siena a "Prodigal Club," and a poet of the day wrote a series of sonnets (translated by D. G. Rossetti) "Unto the blithe and lordly fellowship." [21] _History of the Renaissance in Italy_, iii. 161. THE SCHOOLS OF LOMBARDY Painters of "the loveliest district of North Italy, where hills, and streams, and air, meet in softest harmonies" (RUSKIN: _Queen of the Air_, § 157). 'Twere pleasant could Correggio's fleeting glow Hang full in face of one where'er one roams, Since he more than the others brings with him Italy's self,--the marvellous Modenese! BROWNING: _Bishop Blougram's Apology_. The loose use of the term "school" has caused much confusion in the history and criticism of art. Sometimes the term is used with reference only to the place where such and such painters principally worked. Thus Raphael and Michael Angelo, together with their followers, are sometimes called the "Roman School." But Rome produced no great native painters; she was merely a centre to which painters were drawn from elsewhere. So too when the phrase "Milanese School" occurs, it generally means Leonardo da Vinci and his immediate pupils, because, though a Florentine, he taught at Milan. Sometimes, again, the term "school" is used as mere geographical expression. Thus under "Lombard School" are often included the painters of Parma, simply because Parma is contiguous to Lombardy. A third use of the term school, however, is that in which it means "a definite quality, native to the district, shared through many generations by all its painters, and culminating in a few men of commanding genius." Such a definite quality is generally marked by "a special collection of traditions, and processes, a particular method, a peculiar style in design, and an equally peculiar taste in colouring--all contributing to the representation of a national ideal existing in the minds of the artists of the same country at the same time." This is the use of the term which is suggested by the main arrangement of the National Gallery, and which is at once the most instructive and the most interesting.
