Extinct Languages Spoken 2 — Old Church Slavonic, Classical Latin, Ancient (Attic) Greek, and more

Watch the previous video (containing Ubykh, Old English, Proto-Germanic, and more): The second video in the series. I decided to focus on Indo-European languages for this one. Featuring (in chronological order): Old Church Slavonic, Old Irish, Gothic, Classical Latin, Ancient (Attic) Greek, Avestan, and the (hypothetical, but very probable) common ancestor of all these ancient languages, Proto-Indo-European.
