It would depend largely I guess on the original Greek version of the name and how it is written.
for example, if “Lycos” is written as “ΛΥΚΟΣ (λυκος)” then I think the name would be pronounced like “leekos”
There is one note about “EU” combination in Greek names. I don’t know how they are pronounced nowadays but in modern Greek it is pronounced as “EV” (Zeus which is said almost like Ziyos or Zoos by some readersis in fact Zevs)!

The way we would pronounce it in my Ancient Greek Class:
Lycos = Λυκος = [lykos]
Nycteus = Nυκτευς = [nykteus]
Epirus = Eπιρυς = [epirys]
The epsilons in Nycteus and Epirus could be zetas but that would only change the pronounciation slightly.

Actually, Epirus is taken from Latin, which latinized the Greek Epiros.

Epirus is the latinized form of Epiros, the Greek word for “Mainland”, which corresponds roughly with modern-day Albania/Northern Greece. Also, in Ancient Greek, as opposed to modern Greek, the diphthongs “eu” and “au” were pronounced like their Latin counterparts. So Zeus would have sounded a bit like Deus in Latin.

How to properly pronounce Minos (one of the judges of the Underworld) and Helios (Sun God)?

Cheri – Minos = me-no-s (pronouncing me and no as in English), and Helios = hay-lee-os

Thanks so much TJ, BJ, Aeneas and Simon for your help, I didn’t know this ‘blog’ was here until I typed my name in google just to see what was there and found this link. I am so glad I did as now I can thank you properly for your input. The first reading of the play was successful and the pronounciations were not as difficult as I thought they would be! Thanks again.

Very good site. Thanks:-)

HOW DO U PRONOUNCE HELIOS

You say “lycos” would be “leekos”
but isn’t the upsilon “y” supposed to be like an umlat, i.e., “oooh”?
