The Lasso of Truth, or Lasso of Hestia, was forged by Hephaestus from the golden girdle of Gaea. The original form of the Lasso in the Golden Age was called the Magic Lasso of Aphrodite. It compels all beings who come into contact with it to tell the absolute truth and is virtually indestructible; in Identity Crisis, Green Arrow mistakenly describes it as "the only lie detector designed by Zeus." The only times it has been broken were when Wonder Woman herself refused to accept the truth revealed by the lasso, such as when she confronted Rama Khan of Jarhanpur, and by Bizarro in Matt Wagner's non-canonical Batman/Superman/Wonder Woman: Trinity. During the Golden Age, the original form of the Lasso had the power to force anyone caught to obey any command given them, even overriding the mind control of others; this was effective enough to defeat strong-willed beings like Captain Marvel. Diana wields the Lasso with great precision and accuracy and can use it as a whip or noose.
To defend himself against critics, Gaines, in 1940, hired Marston as a consultant. “‘Doc’ Marston has long been an advocate of the right type of comic magazines,” he explained. Marston held three degrees from Harvard, including a PhD in psychology. He led what he called “an experimental life.” He’d been a lawyer, a scientist and a professor. He is generally credited with inventing the lie detector test: He was obsessed with uncovering other people’s secrets. He’d been a consulting psychologist for Universal Pictures. He’d written screenplays, a novel and dozens of magazine articles. Gaines had read about Marston in an article in Family Circle magazine. In the summer of 1940, Olive Richard, a staff writer for the magazine, visited Marston at his house in Rye, New York, to ask him for his expert opinion about comics.

Gelignite Grenade Earrings and Grappling Hook Bracelet - In her depowered mod girl phase, Diana on rare occasion employed these devices, which were concealed to look like regular parts of her costume. She acquired them from a demolitions expert and villain which she had helped reform. The grenades were strong enough to blast through a thick steel door and the grappling hook could support easily her body weight to aid in climbing.
