Hi there! I had a quick, private question for you. I help admin an SPN blog, and there was a question we got about "What Hebrew letter is the Mark of Cain based off of?" You wouldn't have any insight into that, would you? :)

If you rotate it 90 degrees to the right you’ll get something like this 

This is the 16th letter in hebrew, it called ‘ayin’ which means ‘an eye’ . 

you can take it to whatever sybolism you want ..i never did. The  Gematria ( an Assyro-Babylonian system of numerology) of this letter is 70.
