I was recently on vacation in New England, and I wandered as far north as New Hampshire and Maine, where I saw two flags I cannot identify.
The first flag I saw was white with a dark blue canton which contained a dark red Latin (or Passion) cross.
The second flag I saw was more complex. It was white with a black snake wrapped around a black anchor sinister (and leaning sinister). Central, it had a red Latin cross. Dexter (and leaning dexter) it had a red spear, point down. Interspersed between the devices was a Greek motto in red. The transliteration of the motto is ELEYTHERIA H THANATOS.
The Greek motto seems to be something about freedom or death. Since you were in New Hampshire, I would guess it to be a Greek rendering of the New Hampshire “Live Free or Die” motto.
Apparently, my transliteration left something to be desired. I correctly rendered the theta, lambda, rho, and sigma, but the H-I transfer eluded me. (Although I thought there was something off about a word consisting of the letter ‘h’.) I only know a few (maybe three) words of Greek (see below), but mathematics demands a knowledge of the Greek alphabet.
Incidentally, I guessed the Live Free or Die' interpretation as well, given my knowledge of one word (thanatos, from my studies of Freud) and the motto of the state I was in (New Hampshire). Liberty or Death’ is probably a much better rendering, although I can’t help but notice the similarity.
(The flag was displayed in a restaurant that served no greek cuisine whatsoever, but was in a prominent display case alongside the current Greek national flag. Spiced lamb may not sell, but obscure references to one’s nationality can’t hurt. :))
Anyway, thanks for the help. I’m constantly amazed at how much you people can do, even with only a limited amount of information (enough to be scrawled on a paper napkin, in one instance).
