Evidence from the poetic meter of Homer suggests that also occurred in the Archaic Greek of the Iliad and Odyssey, although they would not have been pronounced by Attic speakers and are not written in the Attic-influenced form of the text. The presence of these consonants would explain some cases of absence of elision, some cases in which the meter demands a heavy syllable but the text has a light syllable ("positional quantity"), and some cases in which a long vowel before a short vowel is not shortened (absence of epic correption).
