In 1117, the Althing decided that all the laws should be written down and this was accomplished at Hafliði Másson's farm over that winter and published the following year. The resulting codex is known as the "Gray Goose Laws" (Icelandic: "Grágás") and they were a collection of laws from the Icelandic Commonwealth period consisting of Icelandic civil laws and the laws governing the Christian church in Iceland.
