since i'm kind of a nerd i decided to get a tattoo based on the Dune series of books. One of the main characters, Duke Leto Atreides, is said to be descended directly from Agamemnon and is my favorite character. I will be getting a tattoo of his ducal emblem (a red hawk on a banner of green and black) just below my right collarbone and I would like to have something he said written under it in ancient greek.
The quote is "never forget compassion".
I've tried to look up translations for these words and tried to call upon my high school greek knowledge (which has almost completely abandoned me) and am fed up and would greatly appreciate any help. I realize there are many ways to translate these words and would appreciate a few options, if you don't mind.
thank you very much.
