The Epic Lay of Kossovo, sung from generation to generation by peasant bards to the strains of the stringed guzla in the remotest mountain glens and the busiest market places, has still been a common heirloom of the whole people. It has kept alive the tradition of national unity and green the memory of heroic deeds, and held up withal the traitors of the past to perpetual obloquy. The lesson brought homer by it is one which all members of the Southern Slav race take to heart to-day. It is summed up in the Serbian motto “Samo Sloga Srbina Spasava” — “Union only saves the Serbs”.
