Statues of Agrippa and Augustus side by side on the Cologne City Hall. It was Agrippa who first settled the Germanic tribe of the Ubii in the area and the settlement was known as Ara Ubiorum.
Agrippa's granddaughter Agrippina the Younger was born in the town, which became an important military base, in 15 AD when her father Germanicus was campaigning against the Germans. In 50 AD on Agrippina's urging Claudius promoted it to the Colony and it was renamed Colonia Claudia Ara Agrippinensium. Her statue is also featured on the city hall, a short space from these two.
Ms. Codex 1233 is a pretty amazing manuscript. Originally written in the early-to-mid 15th century, it was used continuously through the end of the 18th century. Written in Cologne and probably used by the canons in the Cologne Cathedral, this notated breviary (a liturgical book containing the canonical hours - daily prayers - with musical notation) includes notes and additions made up to 1794. It also includes splatters of candle wax and one page that got a little too close to a candle!
