(M24) It appears to have been a Zulu custom to put the king to death as soon as he began to have wrinkles or grey hairs. At least this seems implied in the following passage written by one who resided for some time at the court of the notorious Zulu tyrant Chaka, in the early part of the nineteenth century: “The extraordinary violence of the king’s rage with me was mainly occasioned by that absurd nostrum, the hair oil, with the notion of which Mr. Farewell had impressed him as being a specific for removing all indications of age. From the first moment of his having heard that such a preparation was attainable, he evinced a solicitude to procure it, and on every occasion never forgot to remind us of his anxiety respecting it; more especially on our departure on the mission his injunctions were particularly directed to this object. It will be seen that it is one of the barbarous customs of the Zoolas in their choice or election of their kings that he must neither have wrinkles nor grey hairs, as they are both distinguishing marks of disqualification for becoming a monarch of a warlike people. It is also equally indispensable that their king should never exhibit those proofs of having become unfit and incompetent to reign; it is therefore important that they should conceal these indications so long as they possibly can. Chaka had become greatly apprehensive of the approach of grey hairs; which would at once be the signal for him to prepare to make his exit from this sublunary world, it being always followed by the death of the monarch.”(70) The writer to whom we are indebted for this instructive anecdote of the hair-oil omits to specify the mode in which a grey-haired and wrinkled Zulu chief used “to make his exit from this sublunary world”; but on analogy we may conjecture that he did so by the simple and perfectly sufficient process of being knocked on the head.
