There are ancient goddess traditions around the world, and for this project, you could zoom in on the goddesses of a specific culture, or you could find a way to bring goddesses from different cultures together.
Research Tip: There is a List of Goddesses at Wikipedia, but you will actually have better luck with the Lists of Deities, which will take you to lists of gods and goddesses, culture by culture, like the List of Japanese Deities — just use "Control-F" to find the goddesses on that page, and then click to go to the individual article about each goddess.
