Typically a classical symphony especially in the 18th century followed a distinct order of sonata-allegro for an opening or as an introductory. Then the theme and variations which would give way to the minuet and trio. Lastly you can use the rondo and also a sonata I believe. That's just from my experiences from listening to multiple sources of compositions.
As I remember from history, the Romans admired the human body. They loved the way the body was shaped and just how it was. That is possibly why they took detail into the human sculptures.
Johann Sebastian Bach
Johann Sebastian Bach March 1685 – 28 July 1750) was a German composer and musician of the late Baroque period. He is known for instrumental compositions such as the Cello Suites and Brandenburg Concertos; keyboard works such as the Goldberg Variations, The Well-Tempered Clavier and the Toccata and Fugue in D minor; and vocal music such as the St Matthew Passion and the Mass in B minor. Since the 19th-century Bach Revival, he has been generally regarded as one of the greatest composers in the history of Western music.
