Bunin's travel sketches were lauded as innovative, notably "Bird's Shadow" (1907–1911). "He's enchanted with the East, with the 'light-bearing' lands he now describes in such beautiful fashion... For the East, both Biblical and modern, Bunin chooses the appropriate style, solemn and incandescent, full of imagery, bathing in waves of sultry sunlight and adorned with arabesques and precious stones, so that, when he tells of these grey-haired ancient times, disappearing in the distant haze of religion and myth, the impression he achieves is that of watching a great chariot of human history moving before our eyes," wrote Yuri Aykhenvald. Critics noted Bunin's uncanny knack of immersing himself into alien cultures, both old and new, best demonstrated in his Eastern cycle of short stories as well as his superb translation of Henry Wadsworth Longfellow's "The Song of Hiawatha" (1898).
