The Indiscreet Jewels by Denis Diderot

I will pass lightly over Mangogul's first years. The infancy of princes is the same with that of the rest of mankind; with this difference, however, that princes have the gift of saying a thousand pretty things, before they can speak. Thus before Erguebzed's son was full four years old, he furnished matter for a volume of Mangogulana. Erguebzed, who was a man of sense, and was resolved that his son's education should not be so much neglected as his own had been, sent betimes for all the great men in Congo; as, painters, philosophers, poets, musicians, architects, masters of dancing, mathematics, history, fencing, etc. Thanks to the happy dispositions of Mangogul, and to the constant lessons of his masters, he was ignorant in nothing of what a young prince is wont to learn the first fifteen years of his life; and at the age of twenty he could eat, drink, and sleep, as completely as any potentate of his age.

Erguebzed, whose weight of years began to make him feel the weight of his crown, tired with holding the reins of the empire, frighted at the disturbances which threatened it, full of confidence in the superior qualifications of Mangogul, and urged by sentiments of religion, sure prognostics of the approaching death or imbecility of the great, descended from the throne, to seat his son thereon: and this good prince thought he was under an obligation of expiating, by a retirement, the crimes of the most just administration, of which there is any account in the annals of Congo.
