Surely aeolian harps are among the first autophones, going back to Old
Testament days.  A wonderfully comprehensive 4-volume set of books cov-
ering history and design of these hauntingly beautiful instruments is:

"Aeolian Harp" by Jonathan Mansfield. (1970)  Series Editor: Stephen
Bonner.  Printed and published by: Bois de Boulogne, 59 Moorfield Rd.,
Duxford, Cambridge, CB2 4PP  United Kingdom

Enjoy!
