Hypaspists
A hypaspist (Greek: Ὑπασπιστής "shield bearer" or "shield covered") is a squire, man at arms, or "shield carrier". In Homer, Deiphobos advances "ὑπασπίδια" or under cover of his shield. By the time of Herodotus (426 BC), the word had come to mean a high status soldier as is strongly suggested by Herodotus in one of the earliest known uses:
"Now the horse which Artybius rode was trained to fight with infantrymen by rearing up. Hearing this, Onesilus said to his hypaspist, a Carian of great renown in war and a valiant man..."
A similar usage occurs in Euripides's play "Rhesus" and another in his "Phoenissae". Xenophon was deserted by his horse in a particularly sticky situation. A hypaspist would differ from a skeuophoros in most cases because the "shield bearer" is a free warrior and the "baggage carrier" was probably usually a slave. The word may have had Homeric and heroic connotations that led Philip II of Macedon to use it for an elite military unit.
