The works were composed for a large Parisian orchestra called "Le Concert de la loge Olympique" (Orchestra of the 'Olympic' (Masonic) Lodge). This organization consisted in part of professionals and in part of skilled amateurs. It included 40 violins and ten double basses, an extraordinary size of orchestra for the time. (Haydn's own ensemble at Eszterháza was never larger than about 25 total.) According to Robbins Landon, "The musicians wore splendid 'sky-blue' dress coats with elaborate lace ruffles, and swords at their sides." They performed in a large theater with boxes in tiers. The performances were patronized by royalty, including Queen Marie Antoinette, who particularly enjoyed the Symphony No. 85, giving rise to its nickname.
