"Take the vitriol which is of the colour of the throat of the peacock (i. e. blue vitriol), saffron, calamine, as also the excrement of a young calf, the poisons, powdered *Plumbago zeylanica*, all in equal proportions, rub them with acids and dry in the shade. Having added honey to the above mixture, smear it on a thin sheet of lead. When roasted in a covered crucible, the lead is coloured in no time; the lead which is now of beautiful colour is fit for bedecking the persons of the gods."
XVII. 70-74.
