Explain to me the following article briefly:
Inattention or simple forgetfulness? Damage in one of the oldest churches in Ortigia, in the prestigious living room of Syracuse. It will be necessary to establish the causes of the fire that, between Sunday night and Monday, inside the parish church of San Paolo Apostolo, in Ortigia, in the historic center, behind the temple of Apollo, damaged some parts of the religious building.
According to the first reconstruction carried out by the investigators – however, further investigations are still ongoing to reconstruct the exact dynamics of the fire – it seems that the flames broke out inside the early Christian temple, which is located in via dell’Apollonion, in the neighborhood once inhabited by fisherman families because of a candle left lit from the previous evening, while the traditional Easter vigil was taking place, at the conclusion of the solemn mass celebrating the Resurrection of Jesus.
The fire, according to what was ascertained, occurred once the church was closed and developed slowly. Now, according to the initial investigations, there is damage to the structure: the fire caused damage and the collapse of part of the lintel of what is considered the oldest place dedicated to the memory of the apostle Paul, who according to the acts of the apostles landed in Syracuse and stayed there for a few days.
