Branwen Daughter of Llyr; Cauldron connection

Cauldron, a large metal pot used for cooking over an open fire? Or possibly, a gateway to hell. In this short story a cauldron was brought about from the Lake of the Cauldron, or “the underworld,” by a Satan figure and a pregnant woman. Cauldrons symbolized powers of resuscitation, so by bringing it to earth he gave soldiers the power to come back to life. However, they couldn't speak, which in return caused them to be a nuisance, rather then doing any good. Which, to me, indicates that once entering the cauldron, Satan now controlled a part of you, which is how he spread his evil. This rapidly started to ruin the rapport between the community, causing people to turn on each other. The second bomb this Satan figure dropped on the Irish was having him and this pregnant woman, who had a offspring who had been promised to be coated in amour at birth, stay with the people. They slowly started poisoning people against one another until the Irish rose up and tried to burn them to death. The family managed to survive the rapid heat however, which also reinforces the idea that the giant man his family have been sent from hell. They then manage to escape and flee with the cauldron to the Island of the Mighty. The fact that they managed to escape with their lives and remain undefeated correlates with the idea of how Satan is a fallen angle who can’t be defeated. And due to this I have confidence in the fact that Satan brought about these plagues to poison the people on earth and turn them against each other, in hopes of creating war.
