Hydraulis reconstruction

The Archeology Channel has a video on the reconstruction of the ancient
Greek Hydraulis:

http://www.archaeologychannel.org/

there are a couple of links there also to other sites about the hydraulis,
but nothing really substantial, and nothing that I could see concerning
tuning, keyboard set up, etc. Has anyone come across any info about this
elsewhere?

I also came across this sample chapter from a book on the clavichord, which
has some interesting pics of monochords etc.
