Just a taster, the full story can be read here:
''Little is know of the parents of Petrus Gonzales as he was taken, as an infant, from his home in the Canary Islands to be presented to King Henri II in Pairs. Why was Petrus of such interest? Petrus Gonzales’s entire body – including his face, was covered in long, wavy hair and he was an immediate medical sensation.
In 1557, the first formal report appeared, written by Julius Caesar Scaliger. In his report about the famed boy of Paris, Scaliger referred to the lad as Barbet – the same name used to identify a breed of shaggy dog''.
