Said to be Adam and Eve’s first daughter and the beautiful twin sister of Cain, according to “The First Book of Adam and Eve,” Luluwa is said in the text to be promised to the good-hearted Abel. Cain, seemingly marked from the very beginning as a bad seed, is upset that this leaves him with the supposedly ugly twin of Abel, Aklia. But, as Satan tells Cain, if Abel happened to get murdered suddenly, then Luluwa would be free to marry Cain.
Cain proceeds to do all of that, even to the point of marrying Luluwa without getting permission from their parents (or, it seems, bothering to ask for consent from Luluwa herself). In “The Second Book of Adam and Eve,” he sets up home not too far from where he killed Abel and proceeds to have children with Luluwa. Turning to Genesis 4:16-17, the banished Cain leaves wherever it is that his parents have settled and sets out to the mysterious land of Nod, where he founds a city.
No document or folktale bothers to mention how Luluwa might feel about all of this, though marrying her murderous brother and moving away from her parents would have surely been difficult. If we’re to believe first-century historian Josephus, then Cain continued on being an evil jerk who built up his city’s wealth via robbery. He doesn’t exactly sound like prime husband material, even when very few others were available for the job.
