Kvasir is the wisest of the Vanir gods. Talking about the origin of this god is a bit gruesome, but he was born from the spit of two groups of gods – Aesir and Vanir.
That was when the war
between the Aesir and the Vanir ended. To come to a peace agreement, they work together to create a magic wine according to the ancient method. The method was tatkuink clothing that each deity would chew the fruit and then spit it into a bucket. Then the gods "decided not to let it go to waste, and thus created a human" as the water fermented and it was Kvasir who could answer any question.
Perhaps because he was absorbed in the "essence" of the gods, Kvasir was extremely wise. He is the wisest of the gods and there is no question he has no answer.
Kvasir often roamed the world
Sharing his knowledge and wisdom with the world. Unfortunately, Kvasir was later killed by two greedy dwarves because he was jealous of his wisdom.
When Loki was in hiding because he was being pursued by the gods, Kvasir was the first to enter Loki's house and from the form of a net in the ashes of the fireplace realized that Loki was in the form of a fish, and so the gods caught him. Loki is about to heal.
Kvasir travels the earth, teaching people knowledge, sharing his wisdom. Tired of Kvasir's preaching, the two dwarves - Fjalar and Galar invite Kvasir to feast in their cave and kill Kvasir. The god's blood was poured into two jars, Són and Bon, and the Óðrerir. Fjalar and Galar then mixed the god's blood with honey in the Óðrerir flask, creating a poetic mead. Whoever drinks this mead will be inspired by poetry and wisdom.
Some time later
two dwarf brothers killed the giant Gilling and his wife. Gilling's son, the giant Suttungr, forced the dwarves to give him mead, and left it to his daughter Gunnlöð to guard in a cave in Jotunheimr. However, Odinn had heard of this mead, and decided to drink it womens skull clothing himself. The god disguised himself as a tenant farmer with the name Bölverk, and worked for a year for Baugi - Suttungr's younger brother. I convinced Baugi to let me drink mead, by sneaking into the cave and luring Gunnlöð into giving him three sips.
In chapter 4 of the Ynglinga saga, Kvasir, one of the Vanir gods and described as "the most intelligent", is also among the hostages exchanged.
According to the book "Nordic Mythology" by Kevin Crossley-Holland, the name Kvasir is derived from the Russian word kvas, which refers to a fermented drink that resembles beer but is stronger. The root kvas– may also be derived from the pre-German word kvass - meaning "squeeze, compress, squeeze, crush", so the name Kvasir may be related to the liquid (saliva), from which Kvasir is created.
