Note 209 — Chapter VI · The Gold Unit everywhere the value of a Cow.
Reading edition
This is almost exactly the weight of the örtug, into 3 of which the ora (ounce) of 410 grs. was divided. The örtug of gold being 136·7 grs., and the value of a cow being 128 grs. of gold, it is hard not to believe that there was a connection between them. (See App. C.)
