Within four niches are the statues of the saints: St. Bartholomew to the church, then clockwise St. Francis, St. John of God and St. Paulinus bishop. The names are listed at the top of the niches.
(See the website News and monographs -> San Bartolomeo -> Square and a facade )
Why these four saints in that position and why? San Bartolomeo is the owner of the Basilica (formerly dedicated to St. Adalbert) and of course the statue is pointing towards the church.
For the same reason the other side, to the hospital S. John Calibita - Fatebenefratelli, is the statue of St. John of God, founder of the Fatebenefratelli. Towards
Trastevere, but at the time of construction of the spire on that side there was still the Franciscan monastery, now demolished, is the statue of St. Francis: This memory of custody of the basilica to the Franciscans in 1524. Further reference S. Francis and the chapel in the right aisle of the church dedicated to him.
last niche is the statue of St. Pauline Bishop, whose relics are found in the chapel in the Basilica of Molinari and whose name is included, together with that of St. Bartholomew, less visible in the inscription on the entrance door of the basilica, dated 1113, reminiscent of the oldest relics transferred to the basilica by Otto III.
