Stassov, in his fine monograph upon the composer, lays stress on this view of Glinka's career. The history of art, he argues, contains only too many instances of perverted talent; even strongly gifted natures have succumbed to the ill-judged advice of friends, or to the mistaken promptings of their own nature, so that they have wasted valuable years in the manufacture of works which reached to a certain standard of academic excellence, and even beauty, before they realised their true individual vocation and their supreme powers. Glinka was fortunate in his parents, who never actually opposed his inclinations; and perhaps he was equally lucky in his teachers, for if they were not of the very highest class they did not at any rate interfere with his natural tendencies, nor impose upon him severe restrictions of routine and method. Another happy circumstance in his early life, so Stassov thinks, was his almost wholly feminine environment. Glinka's temperament was dual; on the one hand he possessed a rich imagination, both receptive and creative, and was capable of passionate feeling; in the other side of his nature we find an element of excessive sensibility, a something rather passive and morbidly sentimental. Women had power to soothe and at the same time to stimulate his temperament. Somewhere in his memoirs, Glinka, speaking of his early manhood, says: "At that time I did not care for the society of my own sex, preferring that of women and girls who appreciated my musical gifts." Stassov considers that these words might be applied to the whole of Glinka's life, for he always seemed most at ease in the company of ladies. In the autumn of 1817, being then thirteen, he was sent to the newly opened school for the sons of the aristocracy, where he remained until 1822. His schooldays appear to have been happy and profitable. He was industrious and popular alike with the masters and pupils. In the drawing class the laborious copying from the flat, with its tedious cross-hatching and stippling then in vogue, soon disgusted him. Mathematics did not greatly interest him. Dancing and fencing were accomplishments in which he never shone. But he acquired languages with a wonderful ease, taking up Latin, French, German, English and Persian. In after years he dropped to some extent Persian and English, but became proficient in Italian and Spanish. Geography and zoology both attracted him. That he loved and observed nature is evident from all his writings; and the one thing in which he resembled other boys was in his affection for birds, rabbits, and other pets. While travelling in the Caucasus in 1823 he tamed and kept wild goats, and sometimes had as many as sixteen caged birds in his room at once, which he would excite to song by playing the violin.
