By now, anyone who has ever been a fan of DC Comics is aware that early Wonder Woman comics had some bondage themes. This was largely, in part, due to William Marston’s BDSM and polyamory lifestyle.

BDSM has been practiced in various forms since ancient times. One of the earliest known references to the practice of bondage is The Tomb of Whipping near Tarquinia in Italy. The tomb’s walls depict scenes, said to have been influenced by followers of the Greek god Dionysus.
