Chronica regia Coloniensis

[1] According to the historian Manfred Groten, the Chronica was probably first compiled about 1177 in Michaelsberg Abbey, Siegburg, and then continued in Cologne.

Up to 1106 the Chronica depends on the works of Frutolf von Michelsberg and Ekkehard of Aura, and then on until 1144 on the now lost Annales Patherbrunnenses.

The author of the Chronica sancti Pantaleonis made use of the royal chronicle to cover the years down to 1199, and the historian Georg Waitz treated the former as a mere continuation of the latter and edited them together.

The author of the Chronica had access to a letter of Rainald of Dassel, archbishop of Cologne, which gave him important information on the emperor's Italian expedition of 1166.

A continuator included an account of how the crusaders captured Alcácer do Sal, now known as the Gesta crucigerorum Rhenanorum.
