René Guénon first traveled to Cairo in 1930 in the company of Mary Schillito (image to right), who I identified in Against the Modern World as a convert to Islam on the basis that she had taken the first name Dina. In fact, Dina was the surname of her husband, Assan Dina, who was not Egyptian (as I had wrongly supposed) but rather the wealthy son of an Indian-Mauritian father and a French mother.
Assan Dina died in Egypt in 1928 while traveling home through the Suez canal from India to the chateau that he and Mary had built at Cruseilles in the French department of Haute-Savoie, just south of Geneva. This chateau, the Château des Avenières, contained a remarkable chapel with mosaic wall panels from the tarot, which can be seen on this website. The chateau is now a hotel with a fine restaurant, and those with sufficient funds can book a stay or a table here (though at present it seems to be closed).
Alternatively, those who are looking for somewhere to live in Cincinnati, Ohio, might consider The Lofts at Shillito Place (see here), once the massive department store built by Mary Schillito’s father John Schillito, whose career is described in the Northern Kentucky Tribune (see here).
My thanks to Davide Marino for correcting me regarding Assan DIna.
