consider that Frances Wright was the only writer whose work survives between antiquity and DeWitt—that is to say, for nearly 2,000 years—to have attempted publicly to redeem Epicurus' whole system and reputation, on his own genuine terms.
This is an important point too. Sometimes I think the letter to Cosma Raimondi qualifies, and also that work (forget the name at the moment) by Lorenzo Valli (sp?) but you're right that Wright stands much more clearly in this category.
