in my humanities class, we're getting into greek and egyptian mythology... anyway, these two (the sky goddess and earth god) are always depicted like this. with her spread above him (like a crescent, ya know?) and him sitting back, looking up at her. obviously they're egyptian.
they fell in love but were forbidden to get hitched within the 360 days of the year. so they went to another god for help and got him to add 5 days to the year. they got seriously busy and had a child for each of the 5 days.
