Protagoras was a 5th century BC Greek philosopher. As a sophist, he was a teacher of virtue and pontificated on how a city’s affairs should be properly managed. Street artist MTO leveraged this by calling his mural on Talbot Street the Son of Protagoras. The 2014 street art at the War Memorial features a red hair man holding a dead pigeon. The image represents the conflict between the Irish Catholic nationalists and the Protestant unionists plus the peace walls separating their Northern Ireland neighborhoods. The two arrows bear the symbols of the Knights of Malta and the Latin Cross.
