Hamar Chronicle

Following royal orders from Copenhagen, some of the Catholic archives were to be registered, and lensmann Christen Munk, the son-in-law of Truid Ulfstand, was to be responsible.

He had gathered freeholders with allodial tenure and other secular men together, and together they were to record the most important of the town's buildings, streets, organization and population.

The chronicle goes on to say: Dernest om höy dags tijd beteede sig en gresselig stor orm oc forferdelig, som kaldis Siöormen, udi Miöß, som var gandske lang oc meget stor, oc siuntes at naa fra öens landt oc jnd udi Kongsland[6]: 140  (Next there appeared in the middle of the day an enormously large and abominable sea serpent, called the Sjøorm, in Lake Mjøsa, which was exceedingly long and very large, and it seemed to be coming from the island [i.e., Helgøya, the 'holy island'] and approaching the land of the king.)

[7] Finally, the chronicle describes the occasion and the events of the day that Bishop Mogens was captured and sent to Denmark.

The chronicle states: Hammers vaaben det var en vhrhane med udslagen vinger vdi toppen paa it grönt furutræ[6]: 129  (Hamar's coat of arms was a black grouse with outspread wings at the top of a green pine).
