Ancient Greek Font.

Greek - Τηε γρεεκ αλπηαβετ. Αλτηουγη τηερε αρε μανψ σιμιλαριτιες ηερε ανδ λεττερς ωε ωουλδ ρεξογνισε τοδαψ τηερε ηας αλσο βεεν σομε δραματιξ ξηανγες.

Translation, Helvetica- The Greek alphabet. Although there are many similarities here and letters we would
recognise today there has also been some dramatic changes.

( I found a conversion website where you can type in English and get it changed to Greek called Type Greek - its reliability cannot be 100% certain but it does match the letter i have found in previous research)


For example the symbol for the letter A in upper case is the same as that used in many modern Serif typefaces, the lowercase letter a although recognised as the letter a it takes on a slightly alternative form than the commonly used current typefaces but is similar to more quirky fonts.
Other letters such as r have developed beyond recognition.  φσνπ fjnp. No lines or shape bear resemblance to the current day letters.
