Letter 14 of Pope Gelasius, written on 11 March 494, was addressed to the bishops of Lucania and Bruttium (i.e. nowadays Calabria) and Sicily. They were under Gelasius' direct metropolitan jurisdiction. The long letter is a "decretal", and mainly contains various norms regulating the rights and obligations of clergy.
The same information about the distribution of Church income is given in paragraph 2 of Letter 15 of Gelasius (ed. Thiel 1868: 380), which is the general formulary for his letters, and applied in his Letter 16 (ed. Thiel 1868: 381).
