It is of great significance that it is in this very quarter we find in use as the gold unit not our usual Daric or ox-unit, but its double, which is commonly known as the heavy gold shekel of 260 grains. I have suggested elsewhere that the explanation of this may be due to the fact that among certain peoples, especially those who dwelt after the fashion of the Sidonians, quiet and full of riches, and who had passed from the life pastoral into the settled agricultural stage, the yoke or pair of oxen would readily be regarded as the unit instead of the single ox of primitive days. The fact that a zeugos or yoke of oxen was taken as the unit of assessment by Solon for the third of the Athenian classes lends some support to this view16. We have likewise seen how the ancient Irish, after borrowing the Roman ounce, and equating an ounce of silver to the cow, made for their silver a higher unit by taking three ounces, which represented three cows, the ordinary price of a female slave (cumhal).
The Phoenicians employed the double shekel as their unit, but there is evidence to show that the light shekel was the original unit. We have seen that in Egypt, Palestine and Greece, from the remotest time, gold circulated in the form of rings made of a fixed amount of gold, and also that the unit on which they were made was our ox unit, or light shekel (130-5 grains). From the practice of using gold rings in currency as well as for ornament, we may safely conclude that the standard of 130 grains upon which these were probably made was far anterior to the use of the double shekel in Syria and Phoenicia.
The standards which we have learned from the weights found at Nineveh and Khorsabad are now generally known as the light royal talent, and the heavy royal talent, because on specimens of both standards the inscriptions describe them as weights “of the king.”
