"Girded (for Battle)." A surname of Athena among the Epicnemidian Locrians. Two stone images of Athena, surnamed Girder, are said to have been dedicated by Amphitryon, for it was there that he put on his armor when he was about to give battle to Chalcodon and the Euboeans.

The masculine form is Zosterius.
