with a system of philosophy tended to isolate men from their fellows, the study of the Alexandrine poets, the cultivation of art for its own sake, the exclusive admiration of a particular manner of writing fostered the spirit of literary coteries as distinct from the spirit of a national literature. But making allowance for all these drawbacks, it is to the Alexandrine culture that the education of the Roman sense of literary beauty is primarily due. Along with this culture, indeed, the taste for other forms of art, which was rapidly developed and largely fed in the last age of the Republic, powerfully cooperated. Lucretius specifies among the 'deliciae vitae' Carmina, picturas, et daedala signa;[337] and, in more than one place, he writes, with sympathetic admiration, of the charm of instrumental music, Musaea mele per chordas organici quae Mobilibus digitis expergefacta figurant.[338] The delicate appreciation of the paintings, statues, gems, vases, etc., either brought to Rome as the spoils of conquest, or seen in their original home by educated Romans, travelling for pleasure or employed in the public service, was not without effect in calling forth the ideal of literary form, realised in some of the master-pieces of Catullus. We may suppose too that the cultivation of music had some share in eliciting the lyrical movement in Latin verse from the fact mentioned by Horace, that the songs of Catullus and Calvus were ever in the mouths of the fashionable professors of that art in a later age. If the life of the generation which witnessed the overthrow of the Republic was one of alarm and vicissitude, of political unsettlement and moral unrestraint, it was, at the same time, very rich in its capabilities of sensuous and intellectual enjoyment. The appetite for pleasure was still too fresh to produce that deadening of energy and of feeling, which is most fatal to literary creativeness. The passionate life led by Catullus and his friends may have shortened the days of some of them, and tended to limit the range and to lower the aims of their genius, but it did not dull their vivid sense of beauty, chill their enjoyment of their art, or impair the mastery over its technical details, for which they strove.
