What mental condition could Lydia have suffered from?
When Askeladd shares his past with Thorfinn, we also learn about the environment he and his mother had to survive in.
She was a Welsh noblewoman who was enslaved by Olaf, a powerful Danish lord who then made her serve as his "favorite" concubine, and Askeladd was the product of his rape.
After that, she was thrown out of his manor and lived in a small hut with Askeladd.
I believe Lydia likely starved, and Askeladd had to take care of her from childhood.
She often told him stories about their ancestor Artorius and how he would return to save both of them from their suffering. This may or may not have been true, as she was clearly sick, but it was also something that meant everything to Askeladd, as he deeply loved his mother.
One day, Askeladd describes her having a mental breakdown where she mistook Olaf for their ancestor Artorius and genuinely couldn't tell the difference when looking at him.
Instead, she was happy and smiled at him. She didn't even react when Olaf pulled out his sword to kill her.
I've always wondered what kind of mental condition this could have been. I'm not asking for a clinical diagnosis because I myself am not very experienced in psychology, so I'd appreciate it if you guys could let me know what symptoms you see here and what they might point to.
Thanks.
