Knossos Bull-Vaulting: a Dangerous Sport for Youth.

This is perhaps the kind of dangerous life from which Theseus is credited with freeing captive Athenian youth in the Cretan story. Shakespeare invites comparison to this image in classical praise of the physical élan of Prince Hal and Henry IV's army:

Wanton as youthful goats, wild as young bulls.
I saw young Harry--with his beaver on,
His cuisses on his thighs, gallantly arm'd--
Rise from the ground like feather'd Mercury,
And vault it with such ease into his seat,
As if an angel dropp'd down from the clouds,
To turn and wind a fiery Pegasus,
And witch the world with noble horsemanship.(Part 1, IV.i.103-10).
