Tetradrachm - Seleukos IV Philopator Antioch on the Orontes

Seleukos IV ruled in the shadow of his father Antiochos III's catastrophic defeat at Magnesia in 190 BC, which saddled the empire with an enormous indemnity payable to Rome — 15,000 talents of silver over twelve years. Much of the royal treasury was effectively mortgaged to that obligation, and Seleukos spent his reign quietly managing the financial consequences rather than pursuing conquest. His chief minister Heliodoros, whom he sent to plunder the Jerusalem Temple treasury, ultimately poisoned him in 175 BC.
