With their origins in mythology and their inclusion in Christian architecture, labyrinths were common sights in Europe before the Renaissance, but it was not until the sixteenth century when the ornamental labyrinth became a feature of the formal garden. Architectural treatises, such as this by Sebastiano Serlio, came to include designs for labyrinths and they soon became approved features of Renaissance gardens.
