244 BCE
Ptolemy is meanwhile able to march with his army through the distraught Seleucid realm, penetrating deep into Mesopotamia and reaching at least Seleucia on the Tigris, near Babylon. (According to classical sources, he is compelled to halt his advance because of domestic troubles. Famine and a low Nile, as well as the hostile alliance between Macedon, Seleucid Syria, and Rhodes, are perhaps additional reasons.)
