This is another “marvel at the resources of the internet!” moment. To quote memiyawanzi, where I found the link: “I’ve come across this great index of Ancient Language Resources online Lexicity. It contains an index of online resources for the study of Akkadian, Aramaic, Coptic, Egyptian, Ge’ez, Old Georgian, Gothic, Greek, Hebrew, Latin, Old Church Slavonic, Old English, Old Norse, Sanskrit, Syriac, and Ugaritic, with relevant links to new stuff, out of copyright grammars and texts on archive.org, and so forth.” From their About page:
Learning an ancient language is difficult, but it becomes more difficult if one isn’t part of a high school or college class or doesn’t have access to the more advanced resources of a university library. The natural solution is the internet, where some of those advanced resources are housed and where there is an abundance of materials intended to facilitate one’s study.
However, there are a few problems when turning to the internet. … The solution to these problems is to unite all the resources under a single banner after reviewing them to see which are most useful. Lexicity has done this for 16 of the most prominent ancient languages. All the ancient language resources we feature are free and available to anyone; they’re easy to navigate, easy to sort, and easy to access. You don’t need to be an expert or be willing to wade through 50 pages of search engine results – just visit our languages page to get started.
And what riches are there! Going to the OCS page, I found a link to the Codex Suprasliensis, the largest extant Old Church Slavonic manuscript; I remember it well from grad school days. And that’s just one link of who knows how many! Explore and enjoy.
