Cucuphas was born into a noble Christian family in Scillis (Africa Proconsularis). He and Saint Felix, later martyred at Girona, were said to have been deacons of the Catholic Church in Carthage who arrived at Barcelona to evangelize the area. According to his legend, he functioned as a merchant in Barcelona while preaching the Christian faith, baptizing converts, and aiding the Christian community there. According to Christian accounts of his life, he was generous with the poor and a worker of miracles.
He was martyred near Barcelona during the persecution of Diocletian. Under the Roman governor, he suffered many torments and was imprisoned somewhere near Barcelona, along the twenty-mile stretch between ancient Barcino (Barcelona) and Egara (Terrassa). His throat was finally cut in 304. Tradition holds that two Christian women from Illuro (Mataró), Juliana and Semproniana, buried his body and were consequently martyred as well.
