Camille Flammarion
In 1958, still following the law of Flammarion, Brousse enlarged the planetary family with two "trônes de ténèbres" (seats of darkness), Bacchus and Hercules, respectively 33.9 and 79.5 billion miles from the Sun (magazine "Agni", Perpignan, No. 18, Winter 1958). With flourishing growth, in 1960, he suggested the existence of a new planet named "Flora" 18.6 billion miles from the Sun in his book "De Pythagore à Camille Flammarion" (From Pythagoras to Camille Flammarion) (magazine "Sources Vives", Perpignan, No. 14, Winter 1960). The text builds on his previous writings and follows a hypothesis developed in 1952 by the Italian seismologist Bendandi.
