Incredibly strong, able to stretch and contract, and a magical lie detector created by the Gods of old... What is DC Comics Wonder Woman's lasso of truth made of?
1 Answer
Wonder Woman's Magic Lasso of Aphrodite or Lasso of Truth has two origins.
Post-Crisis origin (more familiar to most fans):
was forged by the god Hephaestus from the Golden Girdle of Gaea that was once worn by Antiope, sister of Hippolyta.
This information comes from Wikipedia
Pre-Crisis, according to the DC Wiki, is much the same (if much less specific):
lasso was formed from Aphrodite's girdle.
As you can see when George Pérez re-booted the Amazonian's origin he went for Gaea, goddess of the earth, rather than Aphrodite. As Pérez had a very different view point on Princess Diana of Themyscira in the 1980's when he worked on her book than William Marston did when he created her in the 1940's.
