De fisco Barcinonensi: De fisco Barcinonensi ("Concerning the Barcelonian Fisc") is a letter ("epistola") from a group of bishops in the province of Tarraconensis in the Visigothic Kingdom to the treasury agents in Barcelona.  The letter reminds the officials of the fixed rate of public tribute and demands that exactions in excess of that amount should stop.  In the manuscripts, "De fisco" is preserved after the acts of the Second Council of Barcelona of 540, but its signatories are mostly those of the acts of the First Council of Zaragoza of 592.  Most scholars believe it should be dated in connexion with the latter council.  The bishops describe themselves as "all [those] who contribute to the fisc of the city of Barcelona", but the bishop of Barcelona, Ugnas, did not sign.  The location of the regional fiscal administration in Barcelona perhaps explains why that city survived the Islamic conquest better than the provincial capital, Tarragona.
