I've been looking at different versions of my Greek Bibles and in the same verse, different Bibles will either write Σωτήρ or σωτήρ. And I'm wondering which of these is correct.
I'm mainly asking this because I am designing a tattoo that is comprised of the intersection of σωτήρ and τετέλεσται, with τετέλεσται going vertical. I was going to leave it as a lower case σ because I feel that the upper case looks out of place with the rest of the design being lower, but if Σ is proper I would stick with using that.
Also, can τετέλεσται be printed vertically and still be read properly?
Thank you for all your help!
