For many centuries, Classical Greek and Latin were considered an indispensable part of any education. This was not just as a means of communication, but because learning those languages is an aid to structured thinking.
Classical studies continue this tradition, including at some well-known Italian and Greek universities. Not only languages are studied, but also ancient literature, mythology, and history. This often serves as an introduction to related subjects like theology and philosophy.
Even if not aimed at some practical purpose, such as a career in tourism or performing arts, a classical studies qualification is seen as a solid liberal arts education. Earning one indicates to employers and the world at large that the student is skilled in research, critical thinking, written and verbal communication, and related skills.
