 They are usually made in pairs.Among the ornaments found belonging to the church of Saint-Riquier, in Ponthieu (813), there is a silver flabellum (Migne, P. L., CLXXIV, 1257), and for the chapel of Cisoin, near Lisle, another flabellum of silver is noted in the will of Everard (died 937), the founder of that abbey.When, in 1777, Martène wrote his "Voyage Littéraire", the Abbey of Tournus, on the Saône river in France, possessed an old flabellum, which had an ivory handle two feet long, and was beautifully carved; the two sides of the ivory circular disc were engraved with fourteen figures of saints.
