Pausanias Description of Greece 9.10.2

[2]
  On the right of the gate is a hill sacred to Apollo. Both the hill and the god are called Ismenian, as the river Ismenus Rows by the place. First at the entrance are Athena and Hermes, stone figures and named Pronai (Of the fore-temple). The Hermes is said to have been made by Pheidias, the Athena by Scopas. The temple is built behind. The image is in size equal to that at Branchidae ; and does not differ from it at all in shape. Whoever has seen one of these two images, and learnt who was the artist, does not need much skill to discern, when he looks at the other, that it is a work of Canachus. The only difference is that the image at Branchidae is of bronze, while the Ismenian is of cedar-wood.

The only difference is that the image at Brankhidai is of bronze, while the Ismenian is of cedar-wood.
