Well, here's one (actually two) that pre-date the Girolamo dai Libri cittern by 85 years. This image was filed under "cithara".
Base-relief carving by Luca della Robbia, 1431-38. See the center pegs, small horns or wings at the body/neck joint, squared little tail extension. These might also have those odd tongue-depressor-like frets. http://www.helsinki.fi/taitu/taidehistoria/kokoelmat/Kipsit/kips100.gif or from here, fourth row down, far right thumbnail "Laudate eum in psaltheris et cithara" http://www.helsinki.fi/taitu/taidehistoria/kokoelmat/kipskuv_r.htm here's the dai Libri instrument again, 1520 http://tinyurl.com/7rjp7 Roger To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
