Daniel 11:21 - Clarke's commentary and critical notes on the Bible

And in his estate shall stand up a vile person, to whom they shall not give the honour of the kingdom: but he shall come in peaceably, and obtain the kingdom by flatteries. In his estate shall stand up a vile person - This was Antiochus, surnamed Epiphanes - the Illustrious. They did not give him the honor of the kingdom: he was at Athens, on his way from Rome, when his father died; and Heliodorus had declared himself king, as had several others. But Antiochus came in peaceably, for he obtained the kingdom by flatteries. He flattered Eumenes, king of Pergamus, and Attalus his brother, and got their assistance. He flattered the Romans, and sent ambassadors to court their favor, and pay them the arrears of the tribute. He flattered the Syrians, and gained their concurrence; and as he flattered the Syrians, so they flattered him, giving him the epithet of Epiphanes - the Illustrious. But that he was what the prophet here calls him, a vile person, is fully evident from what Polybius says of him, from Athenians, lib. v.: "He was every man's companion: he resorted to the common shops, and prattled with the workmen: he frequented the common taverns, and ate and drank with the meanest fellows, singing debauched songs," etc., etc. On this account a contemporary writer, and others after him, instead of Epiphanes, called him Epimanes - the Madman.
