“Otherwise in the halls of our ancestors there were portraits [imagines] to be looked at, not statues by foreign artists, nor bronzes nor marbles: faces modeled from wax were arranged each on individual niches, to be likenesses [imagines] that attend the funeral procession of one belonging to the clan, and always when someone passed away all the people of his family that had ever existed were present. In truth, the family trees ran in lines close by the painted portraits [imagines]. The archives were filled with books of records and written memorials of their deeds performed in civil office. Outside and round the thresholds there were other representations [imagines] of those mighty spirits, with spoils from their enemies fastened to them, which were not permitted to a buyer to unfasten, and the house eternally celebrated their triumph despite the changing of masters.”
Pliny the Elder. Natural History, 35, 6-7.
Óðinn [The Spirited One] went with an army against the Vanir, but they put up a good fight and defended their land, and victory went alternately to both sides. They each raided the other’s land and did damage. But when both sides grew weary of this, they arranged a meeting of reconciliation between them and made peace and gave each other hostages. The Vanir put forward their noblest men, Njǫrðr the Wealthy and his son Freyr, and the Æsir in return the one called Hoenir [“Chicken”, i.e., the material body], and they claimed that he was very suitable to be a ruler. He was a large and most handsome man. With him the Æsir sent the one called Mímir [“The One Who Remembers”], a very clever man, and in return the Vanir put forward the wisest in their company. He was called Kvasir. But when Hoenir came to Vanaheimr he was at once made a lord. Mímir always told him what to do. But when Hoenir was present at councils or meetings where Mímir was not nearby, and any problem came before him, he always answered the same way: ‘Let others decide.’ Then the Vanir suspected that the Æsir must have cheated them in the exchange of men. Then they took Mímir and beheaded him and sent his head to the Æsir. Óðinn took the head and smeared it with herbs that prevented it from decaying, and recited spells over it and imbued it with magic power so that it spoke to him and told him many secret things.
