Mina (unit) in the context of Shekels

Sophaenetus (Ancient Greek: Σοφαίνετος, romanized: Sophainetos) was one of the leaders of the Ten Thousand, an army of Greek mercenaries in the service of Cyrus the Younger, in 401–400 BC. A native of Stymphalus, he was an older man when he recruited and led one thousand hoplites to join Cyrus. He led the army back to the Black Sea and from Trapezus to Cerasus by ship. At Cotyora, he was fined 10 minae for mishandling funds.

The main source for Sophaenetus' career is the Anabasis of Xenophon. Writing in the fifth century AD, Stephanus of Byzantium cites on four occasions a certain Anabasis Kyrou written by Sophaenetus. This is generally presumed to be the same person as mentioned by Xenophon. Stephanus cites him for the names of several places in Asia Minor. The Anabasis Kyrou is not attested outside of Stephanus. The lack of any reference to the work for several centuries after it would have been written is a difficult to explain and its authenticity has been questioned. Some modern scholars regard it as a late forgery, composed after the time of Plutarch. Panico Stylianou suggests that it may be a case of mistaken identity. Pieces of advice attributed to Sophaenetus entered the military handbooks and were misunderstood to refer to a book written by him.

Attic weight, or the Attic standard, also known as Euboic standard, was one of the main monetary standards in ancient Greece. As a result of its use in the coinage of the Athenian empire and the empire of Alexander the Great, it was the dominant weight standard for coinage issued in the Eastern Mediterranean from the fifth century BC until the introduction of the Roman denarius to the region in the late first century BC.

The Attic weight was based on a drachma of 4.31 grams, but in practice the main denomination was the tetradrachm or four-drachma coin, which weighed approximately 17.26 g in silver. For larger sums, the units of account were the mina (100 drachmae or 435 g), and the talent (6,000 drachmae or 26.1 kg).
