When it was written

From 1830 into the following year, the twenty-one-year-old Mendelssohn travelled through Italy. He toured Venice, Florence, Rome and Naples, sketching and listening to music, and wrote home that this symphony would be the merriest piece he had ever written.

The symphony was completed in 1833 on a commission from the Philharmonic Society of London, and he conducted its first performance himself that May. Yet Mendelssohn was never fully satisfied with it and kept revising it, and he did not publish it in his lifetime. The score appeared only in 1851, after his death, which is why it bears the number 4, after the Third, which he wrote later.
