A member of the Roman imperial guard in the second century, Saint Sebastian used his position to encourage imprisoned Christians to persevere in their faith. Arrested and accused before the pagan emperors Maximian and Diocletian, Sebastian was tied to a stake, shot at with arrows and left for dead. Miraculously surviving this torture, he was nursed back to health by Irene, the widow of another martyr, only to be arrested again and bludgeoned to death in the Hippodrome. The dramatic lighting and taut compression of space employed here by Luca Giordano are typical of work he made during his early years in Naples.
