Peristyle of the House of the Golden (or Gilded) Cupids, Pompeii, Italy, March 28, 1921, by Auguste Léon, via Archives of the Planet Collection – Albert Kahn Museum /Département des Hauts-de-Seine.
There are recent photos of the garden here and here and here. It has been restored to what is believed to be its Roman appearance, based on archaeological research, including taking root castings.
This autochrome is one of about seventy-two thousand that were commissioned and then archived by Albert Kahn, a wealthy French banker and pacifist, between 1909 and 1931. Kahn sent thirteen photographers and filmmakers to fifty countries “to fix, once and for all, aspects, practices, and modes of human activity whose fatal disappearance is no longer ‘a matter of time.'”* The resulting collection is called Archives de la Planète and now resides in its own museum at Kahn’s old suburban estate at Boulogne-Billancourt, just west of Paris. Since June 2016, the archive has also been available for viewing online here.
