In 1997, a second monument was officially unveiled by the Greek government, dedicated to the 700 Thespians who fought with the Spartans. The monument is made of marble and features a bronze statue depicting the god Eros, to whom the ancient Thespians accorded particular religious veneration. Under the statue, a sign reads: "In memory of the seven hundred Thespians."
A plate below the statue explains its symbolism:
The headless male figure symbolizes the anonymous sacrifice of the 700 Thespians to their country.
The outstretched chest symbolizes the struggle, the gallantry, the strength, the bravery and the courage.
The open wing symbolizes the victory, the glory, the soul, the spirit and the freedom.
The broken wing symbolizes the voluntary sacrifice and death.
The naked body symbolizes Eros, the most important god of the ancient Thespians, a god of creation, beauty and life.
The monument to the Thespians is placed beside the one to the Spartans.
