The Grand Tour

The Grand Tour was the traditional trip of Europe undertaken by mainly upper-class European young men of means. The custom flourished from about 1660 until the advent of large-scale rail transit in the 1840s, and was associated with a standard itinerary. It served as an educational rite of passage.

It was time for him to perform the tour, which for many generations has been thought necessary to enable the young to take some rapid steps in the career of vice towards putting themselves upon an equality with the aged, and not allowing them to appear as if fallen from the skies, whenever scandalous intrigues are mentioned as the subjects of pleasantry or of praise, according to the degree of skill shewn in carrying them on.
