A Flabellum in Christian liturgical use is ‘a fan of metal, leather, silk, parchment or feathers, intended to keep away insects from the consecrated Body and Blood of Christ and from the priest, as well as to show honour. The ceremonial use of such fans dates back to ancient Egypt’. They fell out of use in the Catholic liturgy in the 14th Century.
