Old Japanese expression

I came across this while I was trying to apply some of the Chinese characters I've learned in Mandarin to Japanese words.

"–ηΖ"

I know that Ζ is pronounced ‚©‚Θ, but I have no idea about –η. I believe that it is an archaic expression. If someone could give me the furigana to this phrase and tell me what it means, that would be excellent.

Thanks!

I believe it's "nari." And yes, it does appear in old or literary Japanese.

I think the reading is ya-kana

–ηis called "Nari" and it means just like "desu" or "da" for current Japanese.

So probably the phrase means "dearuna..."(impressed).
