His prose idylls, The Garden that I love and In Veronica's Garden, are full of a pleasant, open-air flavour, which is also the outstanding feature of his English Lyrics.
The earliest effect of Hallam's death upon his friend's art was the composition, in the summer of 1834, of The Two Voices; and to the same period belong the beginnings of the Idylls of the King and of In Memoriam, over both of which he meditated long.
In the summer of 1859 the first series of Idylls of the King was at length given to the world, and achieved a popular success far beyond anything experienced before by any English poets, save perhaps Byron and Scott.
In 1861 he travelled in Auvergne and the Pyrenees, with Clough, who was to die a few months later; to this year belong "Helen's Tower" and the "Dedication" of the Idylls to the prince consort, "These to his Memory."
He went on quite calmly, however, sure of his mission and of his music. His next volume (1872), Gareth and Lynette and The Last Tournament, continued, and, as he then supposed, concluded The Idylls of the King, to the great satisfaction of the poet, who had found much difficulty in rounding off the last sections of the poem.
