One function of myth is as a cultural teaching tool. It demonstrates moral behavior and outlines the rules and standards applied to different members of society. Religion has often been a tool to reinforce prescribed societal roles, and this includes gender divisions. You can usually infer which activities, behaviors, and physical traits were most strongly coded male or female by looking at the culture's deities, culture heroes, and other legendary figures.

But the gender division in mythology isn't always a firm binary. There are a slew of deities from around the world who are both genders, or neither, or known to switch back and forth on a whim. I'm intrigued by these figures and their roles in their respective pantheons, and thought other folks might find them interesting to learn about, too.
