Apollonius (Seleucid)

Apollonius (Ancient Greek: Απολλώνιος) was a man of the Seleucid Empire who lived in the 2nd century BCE.
He was a friend of the Seleucid ruler Demetrius I Soter when the latter was a young man. When Demetrius, at the age of 10, was sent to Rome as a hostage in 175 BCE, Apollonius went with him, and supported him with his advice. Apollonius had been educated together with Demetrius, and their two families had been long connected by friendship. The father of Apollonius, who bore the same name, had possessed great influence with Demetrius's father, the ruler Seleucus IV Philopator.
