It was elaborated by Johannes Messenius in his drama Disa, which was the first historic play in the Swedish language, and was played at the Disting of 1611. It was also presented in an exaggerated version by Olaus Rudbeck in his Atlantica (1685–89)
The king and the chieftains decided that the population had to be culled by killing all the elderly, sickly and handicapped, and by sacrificing them to Odin. However, Disa, the daughter of the chieftain Sigsten of Venngarn in Uppland, was upset by this cruel solution. She talked mockingly to the king and chieftains about their wisdom and claimed to have wiser words of advice.
In order to test her wits, Freyr asked her to visit him, but she could not do so by foot, by horse, in a wagon, nor in a boat. She could not visit him either dressed or undressed. The time must not be within a year nor within a month, and neither during daytime nor nighttime, and neither when the moon was waxing nor waning.
She passed the test by harnessing two young men to a sled. By the sled, she had a billygoat and she had one leg over the goat and the other leg in the sled. For clothes she had a net, and she arrived at dusk to the king the third day before Yule, a day which was not counted to the year but was considered to be an additional day between two years.
The democide was cancelled, and according to the behest of the new queen Disa, there was a drawing of lots so that a part of the population was to leave Sweden (then restricted to Svealand), for the northern regions that were later called Norrland, where they were to settle and cultivate the land.
