The monument would be dressed in the typical hoplite panoply of the period, including (at different times), a helmet, cuirass (either of bronze or linen), and a number of shields, etc., would be piled about the base.
It remained on the battlefield until the campaigns of the following seasons (since battles often were fought in the same, relatively few plains amid Greece's numerous mountains), whereupon it might be replaced with a new trophy.
During later eras in the Greek world, intention to build a tropaia might be declared at the battlefield, but in fact, erected at pan-Hellenic sanctuaries such as Olympia or Delphi, further increasing the prestige of the victorious state.
