Description of the Lyon in Edward Topsell’s 1607 bestiary The History of Four-Footed Beasts:

Lyons bones have no marrow in them and are so hard that they will strike fire. Their neck is made of one stiffe bone, without any vertebras. They have five claws on the hinder feet and the balls of their eyes are black. Lyons eat but once in two days, and drink in like manner. Formerly in England a Lyon could tell noble blood from base. There is a variety of Lyon with human faces. As for the rest, the taile of a Lyon is very long, which they shake oftentimes, and by beating their sides therewith they provoke themselves to fight. The nether part of this taile is full of hairs and gristles, and some are of opinion that there is therein a little sting wherewithall the Lyon pricketh itselfe.

He adds, “I would not have the Reader … imagine I have … related all that is ever said of these Beasts, but only [what] is said by many.”
