The composite supersyllabograms ZE & RO with the ideogram for horse in Linear B:

KN 259 N l 21 SSYLS ZE RO

This is one of only two tablets in the entire corpus of Linear B tablets which has two supersyllabograms modifying their ideogram, making them a unique phenomenon. The other one appears in the next post.

While the supersyllabogram ZE, meaning “a team of horses”, is straightforward, RO appears only once on this fragment, and nowhere else on any Linear B tablet or fragment, regardless of provenance. L.R. Palmer, in “The Interpretation of Mycenaean Greek Texts” (1963) defines it as meaning “a part of the horse trappings, made of leather”. I have no reason to discount this interpretation. It is unusual for the ideogram for armour to follow that for horse, and especially for the scribe to indicate that there are two (2) sets of armour for the (chariot) drivers, one for each... unusual because the ideogram for armour almost always follows that for chariot and precedes that for a team of horses. Be it as it may, that is the way the scribe inscribed it; so we'll take it at its face value.
