I wonder if the following punctuation I made in my literary translation for an in-text citation is correct in conventional English. Or should I omit the period after parentheses? Or should I omit the period ending the quotation?
“Both speak of deporting a king who obtains his crown and throne and marries a beautiful princess.” (Abjadian, 1987:147).
Note: In the source language, it was not connected to any sentence before or after it. So I translated it as it was.
