Gymnasiums also had teachers of wisdom and philosophy. Community gymnastic events were done as part of the celebrations during various village festivals. In ancient Greece there was a phrase of contempt, "He can neither swim nor write." After a while, however, Olympic athletes began training in buildings specifically designed for them.[4] Community sports never became as popular among ancient Romans as it had among the ancient Greeks. Gyms were used more as a preparation for military service or spectator sports. During the Roman Empire, the gymnastic art was forgotten. In the Dark Ages there were sword fighting tournaments and of chivalry; and after gunpowder was invented sword fighting began to be replaced by the sport of fencing, as well as schools of dagger fighting and wrestling and boxing.
