And I say once more, if your ladyship does not like to give me the island because I'm a fool, like a wise man I will take care to give myself no trouble about it; I have heard say that 'behind the cross there's the devil,' and that 'all that glitters is not gold,' and that from among the oxen, and the ploughs, and the yokes, Wamba the husbandman was taken to be made King of Spain, and from among brocades, and pleasures, and riches, Roderick was taken to be devoured by adders, if the verses of the old ballads don't lie."
