Take the following as truth: Just across rue St-Jacques stands the exquisite 13th- to 15th-century Flamboyant Gothic church of St-Severin, in which Dante is said to have prayed and Saint-Saans asked to be made honorary organist.
Then the following statement: "It is thought that Dante may have prayed at the church of St-Severin." is true, false, or inconclusive?
