The term "Gordian knot", which is still used in our modern times as a phrase to solve a problem, comes from ancient Greece. According to mythology, King Gordios of Phrygia is said to have knotted his chariot so artfully and perfectly between the yoke and the drawbar that the connection was considered inseparable.

Again and again questions or whole texts about cultural and ancient history of the Greeks and Romans reach us, sometimes they are surprising. Once a clearly recognizable basilica with an apse suddenly becomes a Greek gymnasium, because one probably does not want the rather ecclesiastical character of the basilica, then again it is an amphitheater, a bouleuterion and stadiums that are confusingly described as to be the same.

If we talk of a modern gymnasium (high school) today, we usually have a higher education center in mind, which is attended by students from elementary school to high school graduation.
