ABSTRACT
There is a windmill in Crete and the Aegean islands, with eight sails of canvas only on a horizontal shaft. It is a tower mill; the top of the tower is turned towards the wind. W. Schmidt distinguishes two main groups: The older recension, which is derived from a single archetypus, and the younger recension, which is derived from another archetypus. The wind-wheel is placed in a frame or rack that can be turned to face the wind. Not a word more is said of this frame, nor is it shown in the figure, though its connexion with the rest of the instrument would give rise to several mechanical problems, if the two were connected. W. Schmidt lists eight other places, where the word organon is used by Heron, and in none of them it has anything to do with music.
