Note 4 — Chapter IV · The Grateful Dead and The Poison Maiden.
Reading edition
The existing versions go back to the pseudo-Aristotelian De secretis secretorum or De regimine principum, which was taken from the Arabic in the twelfth century (Hertz, p. 92). It is probable, however, that the tale existed far earlier than this and came from India (Hertz, pp. 151–155).
