Cleinias in Wikipedia
Cleinias, son of (the elder) Alcibiades,, and member of the Alcmaeonidae family, was an Athenian who married Deinomache, the daughter of Megacles, and became the father of the famous Alcibiades. Plutarch tells us that he traced his family line back to Eurysaces, the son of Telamonian Ajax. He greatly distinguished himself in the Battle of Artemisium in 480 BC. Cleinias died at the Battle of Coronea in 447 BC.
He is also credited with the Cleinias Decree, which involved the tightening up of the process of tribute collection in the Athenian Empire. Attributing this inscription to this particular Cleinias, the father of Alcibiades, places the decree in the early 440s, usually given as 447, as Cleinias died at the Battle of Coronea in 447.
