Matt of No-sword has two recent posts (<gue> to fabulas and I just can’t stop talking about old Portugo-Japanese texts online) on translations into Japanese of several books related to Aesop. These books are from the late sixteenth century and are the work of Portuguese Jesuits. And they’re in R?maji.

Here’s a link to the fable of the horse and the ass. For more links, see Matt’s posts.
