Here is my tattoo, just got it last week, still have to go back and get it finished but Im very happy with it. Atheos is written in Greek meaning "without god" and I wanted to convey my views on how everything in existence is here without the some sky daddy's master plan, the cosmos and us alike. And I'm a huge nerd and fascinated with the universe ^_^
If I had to get an atheist tattoo I would go for something that carries deep symbolism, this is my idea:
The link below is to a jpg which is a snapshot of the coine greek word for atheist (atheoi/atheos...without god), from an early manuscript of Ephesians. Next time a Christian stops you you say you have the most important word in the bible tattooed on your ...fill in bank...
I've actually painted an abstract version of this with the words burning in flames which is now hanging on my wall I'll send a picture if you're interested.
Sure I would like to check it out. I'm looking for an idea that represents my happy to be atheist self lol. I've actually gained the interests of what seemed to be good women and they wanted to go the step further with me. Once they found out I was atheist some said horrible things to me, but all stepped out of my life for good. This has got to stop. But I cannot lie because I respect others religion. I just don't like those that are fools. Anyway enough of my rant. If you're still around I'd like to check it out my email is Jasonsmith01@gmail.com :)
There is one I've seen that isn't too obvious. It's Darwin's sketches of the tree of life. If you aren't familiar with them, they simply look like twigs or lines, but if you are, they pretty much spell it out for you.
Or a more contemporary tree of life:
Subtle, very symbolic. I've been considering getting a tattoo of it as well, if I ever get a tattoo.
If you had no other tattoos, and wanted a long one you could get "my other tattoo shows my religious beliefs."
Or you could get Leviticus 19:28 for the irony (the verse forbids tattoos).
If you want something that could be small you could get a symbol like one of these, for example.
