When I was little, my parents sung to me, "vatten, vatten, bara vanligt vatten" which roughly translates to, "water, water, just plain water". However, with the mention of water reoccurring throughout the book, it is very clear that the water serves a deep, purposeful meaning especially regarding the character Beloved.
When one first comes in contact with Beloved, she is seen as a stranger to the ones around her and is very sick. As Denver takes care of her, Sethe and Denver tries to get information from which Beloved comes from, however, she states that she came from the Ohio River, from "the other side, " and doesn't seem to recall any thing that could have possibly happened in her life. Although other motifs like the color white and coldness point to the fact Beloved is a ghost that is seemingly grown up from the age in which she died, the fact that she has remerged from water brings in the idea and symbolism water serves in the bible.
As a non-religous person, when thinking about water and Christianity, my mind goes to baptizing and with the idea of rebirthing. With these things in mind, it makes sense that Beloved has become older through water. In the article linked, it touched up on that "in some contexts, water stands for enemies who can attack and need to be overcome" and it makes me wonder why and how Beloved died, and if it correlates to Beloved strangling Sethe, her mother.
Another character that correlates with water is Denver. She was birthed on a boat as Sethe was escaping Sweet Home. Is there a bible reference of some baby drifting out in water? Could someone clarify?
