The church dedicated to Saint Cecilia is in the charming area of Trastevere and it was built by the pope Pasquale I around 820 after having found the corpse of the saint buried in the III century in the cemetery of St. Callixtus. According to the legend when the corpse was found, it was miraculously intact and because of this it was placed in the church. The same church eventually in 1599 was restored and they decided to check the shrine of Cecilia and again...her body was found in an excellent conservation state. They commissioned then to Stefano Maderno a statue which represents how the saint was lying when discovered the second time: her body was intact and she was showing the symbol of the Holy Trinity, that is three fingers up in one hand and one in the other. Three persons in one.
