You can google the myth and figure out the role of the snake on your own. 

I'm not a prude. Not by a long shot. And honestly I don't really care who is offended by what. Just because I point it out doesn't mean I'm offended by it. You asked me what I saw so I told you what I saw. It's symbolism. It's why art exists in the first place. I just don't get excited over looking at naked bodies like you do. I study anatomy. I look at naked bodies all day long, of all different shapes sizes, colors, genders, ages, dead, alive, with skin, without skin, etc. It's like looking at furniture to me. My days of getting excited over naked people are long gone. I know what they look like on the inside, so that's really all I see anymore. For wall art I like darker more macabre things, or sarcasm, or things that violate the senses.

I'd much rather hang this on my wall than your snake girl. It's far more interesting to me, and I love his music so I can connect to it on a deeper level.
