Try putting the files from dominions3/mods/mythology to dominions3/mods/.

The important thing is having the file that ends in ".dm" in your dominions3/mods folder. Then it will show up properly. If there's a folder for images, it also has to go into dominions3/mods, but just moving everything all at once should work fine.

Sometimes the .dm is in a subdirectory, just open it and you should see the .dm and the image folder. Move them to \mods, together, and it hopefully works.
