Thebes was captured in 291 by Demetrios Poliorketes during his incessant wars. In the face of the combined forces of Pyrrhos, Lysimachos and Ptolemy I he was forced out of Macedon in 288, finally ending up in Asia where he was captured by Seleukos I and interned until he died of drink in 282. Previously, in an attempt to raise support, he had freed Thebes in 287: this coin was struck in honor of that occasion. Since Poseidon was neither important in Boeotia as a whole, or specifically in Thebes, his appearance on both sides of this coin has to be seen as a complement to Demetrios Poliorketes, since he viewed Poseidon as his patron.
