Wanted to share a resource I came across today, hope you find it beneficial.
From the homepage:
"Please enter the award-winning internet encyclopedia of mythology, folklore, and religion. Here you will find everything from A-gskw to Zveda Vechanyaya, with plenty in between.
The mythology section is divided to six geographical regions: Africa, Americas, Asia, Europe, Middle East, and Oceania. Each region has many clearly defined subdivisions that will ease your search.
The Folklore section contains general folklore, Arthurian legends, and fascinating folktales from many lands.
In addition, we feature special interest areas to enhance and refine your research. A Bestiary, legendary heroes, an image gallery, and genealogical tables of various pantheons and prominent houses.
To bring our entities to life, we have created an image gallery, where you will find hundreds of images of all kinds of deities, heroes, and strange creatures of every description.
The encyclopedia will serve the serious researcher, the student, and the casual reader with equal success. Come in and enjoy! Think mythology, think EM!"
