Gibbon

Edward Gibbon wrote a book about the decline and fall of the Roman Empire.

In Northern India lives another gibbon, the hoolock.

Four leopard cubs, a bear cub, a monkey, and a red-cheeked gibbon were found sedated and packed into small cages.

'[…] Suppose that in years to come, when the Church's troubles seem to be over, there should come an apostate of my own trade, a false historian, with the mind of Cicero or Tacitus and the soul of an animal,' and he nodded towards the gibbon who fretted his golden chain and chattered for fruit.
