Интересно, что автор плодотворно встречался с Робертом Грейвсом:

Wasson's work had a considerable influence on Graves toward the end of the fifties, and Graves helped to build Wasson's reputation as an authority on the psychological effects of so - called "magic" mushrooms. Moreover, thanks in large part to Graves, Wasson would rediscover the cult of the psilocybe mushroom - known to the Aztecs as teonanacatl, "flesh of the gods" -and would become one of the first outsiders ever to participate in the ancient all-night ceremony during which the sacred mushrooms were eaten. In a manner of speaking, Graves and Wasson were first introduced by Claudius, when in January 1949 Graves received a letter from Valentina who, with her husband, was investigating the death of the Roman emperor. Graves had quoted in full the three main classical accounts of the crime - by Suetonius, Tacitus and Dio Cassius - at the end of Claudius the God, accounts claiming that Claudius had been served a plate of poisoned mushrooms, managed to save himself, and given a second (andthis time fatal) poison by his physician Xenophon. The Wassons suggested to Graves that the mushrooms Claudius ate were the Amanita caesarea, a tasty and wholesome mushroom, although the assassin hired by Agrippina slipped into the dish some poisonous Amanita phalloides, causing symptoms very similar to the ones Claudius suffered.
