The Iliad and The Odyssey are two of the most enduring works of fiction (or “fiction”, if you prefer) ever composed. Although it is doubtful that they were composed in their entirety by a single individual, they are traditionally attributed to a blind bard called Homer. Recently, The World According to Sound aired a podcast about the language in which these works were composed. A form of ancient Greek that sounded nothing like its modern descendant. According to this, this dialect was a tonal language. An example of a modern tonal language is Chinese.
The story was picked up and, partially, rebroadcast, on NPR’s All Things Considered: The Sound Of Ancient Greek.
