It was common, in many periods of history, for young and wealthy men to go on travels for purposes of education (e.g. the Grand Tour of 17th century aristocrats). Interestingly enough, one of the key principles of the development of early medieval universities was free and unmolested travel of scholars between institutions, independent of civil or religious authorities. This means both teachers and students travelled between universities to teach / find better teachers, respectively.

Off-topic: the phrase "do Erasmus" is unmistakable. I see you're either Portuguese or Spanish ;)
