According to
Plutarch (De Iside et Osiride) and the
Suda (s. v. Μανήθως), the Egyptian priest
Manetho (ca. 300 BCE) is said to have written a treatise called "On the preparation of kyphi" (Περὶ κατασκευη̑ϛ κυφίων), but no copy of this work survives. Three Egyptian kyphi recipes from Ptolemaic times are inscribed on the temple walls of
Edfu and
Philae. Greek kyphi recipes are recorded by
Dioscorides (
De materia medica, I, 24),
Plutarch and
Galen (De antidotis, II, 2). The seventh century physician
Paul of Aegina records a "lunar" kyphi of twenty-eight ingredients and a "solar" kyphi of thirty-six. == Production ==
