Trianon (Versailles) – Veue du Chateau de Trianon du coté du Parterre du Parque de Versaille

Optica of Trianon

In the eighteenth and nineteenth centuries there were many popular specialty establishments in Paris, Augsburg and London which produced optical viewing devices and special engravings to be viewed through them. In the 18th century the optical print or vue optique came into existence, whose exaggerated converging lines were intended to produce the optical illusion of deep recession. The viewing devices for which these perspective prints were produced consisted of a lens and a mirror, this requiring the use of reversed or mirror-image pictures.
