English to Turkish Art/Literary History Designating Parts of Hist

Greetings,

Please, how do you say ‘late’ when referring to the early part of a historical period?

It's the same text as before.

I quote:
Hall of Worthies or Jiphyeonjeon was the royal research institute for academic research and also served as advisory to the King in the late Goryeo and early Joseon period.

(On the creation of the Korean alphabet)

Best wishes, and many thanks,

Simon
