The successive stages of Greek are Mycenaean, Classical, Koine, Byzantine, and Modern.
Please submit sites on Mycenaean period Greek, which are principally about its writing system, to
Science/Social_Sciences/Language_and_Linguistics/Graphemics_and_Orthography/Linear_B/
Please submit sites on Koine and Classical Greek to those specific subcategories.
Please submit all other sites to the main category.
Strictly defined, Classical Greek is the principal language which was spoken in Greece and her colonies during the fifth and fourth centuries BC. This category, however, covers the Greek from a few centuries either side to include both Homer and the bible.
Please submit to this category any site which is principally about pre-4th century BC Greek, or Greek from a later period written in this style; Koine Greek (e.g. the Greek of the Bible) has a separate sub-category.
