context: Title: Lansing Main Street Historic District
  Passage: The Lansing Main Street Historic District is a nationally recognized historic district located in Lansing, Iowa, United States.  It was listed on the National Register of Historic Places in 2014.  At the time of its nomination the district consisted of 51 resources, including 42 contributing buildings, 8 non-contributing buildings, and one non-contributing site.  The district covers most of the central business district, which is generally along Main Street.  The commercial buildings are mostly masonry structures constructed with bricks or native limestone.  A few buildings are frame construction with gable roofs.  The buildings are from one- to three-stories in height, although most are no taller that two stories.  The Italianate architectural style dominates.  Most of the upper stories in the buildings housed retail or office space, but a few were residential.  The commercial buildings that did not house retail establishments were located near the Mississippi River and were industrial in nature.  The G. Kerndt & Brothers Office Block (1861) and the G. Kerndt and Brothers Elevator and Warehouses, No. 11, No.12 and No. 13 (1868) are individually listed on the National Register.  Three public buildings are located in the district: the former jail and fire station (ca. 1855-1865), the Art Deco former City Hall (1938), and the modern U.S. Post Office (c. 1960).
  Title: De fisco Barcinonensi
  Passage: 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.
