The New Argonauts

From the author's introduction:

This book is intended to be enough information to let you run a short campaign (8-12 sessions or even longer) set in mythic Greece. If you like Troy, Clash of the Titans, Jason and the Argonauts, or similar movies, this book is the key to heroic adventure. Heroes are masters of the sword and spear, magic is in the hands of the gods or of mysterious sorcerer-women, and the world’s monsters are unique creatures born of the gods or special circumstances rather than members of a race of similar-shaped things. This is what I call “an Argonauts campaign.”
