Note 45 — Chapter III
Reading edition
It should be noted that a few of the early cylinder-seals found at Fâra Andrae considers to have been engraved with the help of the wheel (see "Mitteil. der Deutsch. Orient-Gesellschaft," No. 17, p. 5). The suggestion has also been made that, on the introduction of harder stones, the cutting tool may have been tipped with a flake of corundum; cf. Hayes Ward, "Cylinders and other Oriental Seals," p. 13.
