Hold! You crafty ones, strangers to work, and pilferers of other men’s
brains. Think not rashly to lay your thievish hands upon my works. Beware!
Know you not that I have a grant from the most glorious Emperor Maximillian,
that not one throughout the imperial dominion shall be allowed to print or
sell fictitious imitations of these engravings? Listen! And bear in mind

goods be confiscated, but your bodies also placed in mortal danger.
Albrecht Dürer 1511
