Ok, this one has apparently stumped the pros.

I'm really surprised no one guessed the composer. Who is a symphonist that has a sense of humor and trickery? Of course, it is Haydn. His Symphony No.47 in G Major has a Minuet and Trio, each
al Rovescio. Interestingly, this music was later added (transposed and slightly modified) as the Minuet al Rovescio and Trio al Rovescio for the Piano Sonata in A Major No.41 (Robbins-Landon, Hob. XVI/26).

You will note on page 6 that the Minuet and Trio are each the same music forwards and backwards (palindromes). Then
Minuet da capo.
