Amo was an 18th century West African philosopher from what's now known as Ghana.
One of his works is available here:

But it's in latin, which, I don't know if that's readable.
Right now the earliest english translation of any of his work I can find is from the 1960s, but I thought I'd leave my notes here in case I found more later or someone else had thoughts on the feasibility of a recording.
