Myth Graph is a project from 2005 for presenting mythology and relationships between divinities. Details available here
The material has been taken from Graves's book, that is a very detailed reference on the topic.
This small project uses RDF for representing the information and producing from that both a SVG and Hyperlinked PNG versions by using the amazing GraphViz software.
See also on YouTube the work of my collegues at PERCRO in the domain of storytelling for children, involving also fun-teaching of Mythology [http://www.youtube.com/watch?v=h1ZoOtswW2M]
