in this sequence is problematic because he worked on it for over a decade, starting the sketches soon after he began work on No. 5 but completing it after both Nos. 5 and 4. The Symphony No. 1 in C minor for full orchestra was written in 1824, when Mendelssohn was aged 15. This work is experimental, showing the influences of Beethoven and Carl Maria von Weber. Mendelssohn conducted the symphony on his first visit to London in 1829, with the orchestra of the Philharmonic Society. For the third movement he substituted an orchestration of the Scherzo from his Octet. In this form the piece was a success, and laid the foundations of his British reputation. During 1829 and 1830 Mendelssohn wrote his Symphony No. 5, known as the Reformation. It celebrated the 300th anniversary of the Reformation. Mendelssohn remained dissatisfied with the work and did not allow publication of the score. Mendelssohn's travels in Italy inspired him to compose the Symphony No. 4 in A major, known as the Italian Symphony. He conducted the premiere in 1833, but did not allow the score to be published during his lifetime, as he continually sought to rewrite it. The Scottish Symphony (Symphony No. 3 in A minor) was written and revised intermittently between 1829 (when Mendelssohn noted down the opening theme during a visit to Holyrood Palace) and 1842, when it was given its premiere in Leipzig, the last of his symphonies to be premiered in public. This piece evokes Scotland's atmosphere in the ethos of Romanticism, but does not employ any identified Scottish folk melodies. He wrote the symphony-cantata Lobgesang (Hymn of Praise) in B-flat major, posthumously named Symphony No. 2, to mark the celebrations in Leipzig of the supposed 400th anniversary of the printing press by Johannes Gutenberg; the first performance took place on 25 June 1840. Other orchestral music Mendelssohn wrote the concert overture The Hebrides (Fingal's Cave) in 1830, inspired by visits to Scotland around the end of the 1820s. He visited Fingal's Cave, on the Hebridean isle of Staffa, as part of his Grand Tour of Europe, and was so impressed that he scribbled the opening theme of the overture on the spot, including it in a letter he wrote home the same evening. He wrote other concert overtures, notably Calm Sea and Prosperous Voyage (Meeresstille und glückliche Fahrt, 1828), inspired by a pair of poems
