Atlamál in grœnlenzku (The Greenlandic Lay of Atli) is one of the heroic poems of the Poetic Edda. It relates the same basic story as Atlakviða at greater length and in a different style. The poem is believed to have been composed in Greenland, most likely in the 12th century.
Plotting to kill his brothers-in-law, Atli dispatches messengers to Gunnarr and Högni, the sons of Gjúki, with an invitation to his hall.Guðrún, daughter of Gjúki and Atli's wife, learns about the plot and sends a runic message to her brothers but the runes are corrupted by one of the messengers, Vingi. Nevertheless, Kostbera, Högni's wife, discerns from the runes that something is wrong and warns Högni. Högni dismisses her fears but she persists and describes dreadful dreams she has had, interpreting them as warnings. Högni remains unmoved and explains the dreams away. Glaumvör, Gunnarr's wife, has also had bad dreams which she describes to her husband, who also attempts to explain them away. Eventually Gunnarr admits that their lives may be short but tells Glaumvör that he cannot evade his doom. The brothers set out to Atli with only three companions. The women follow the brothers to a fjord where their ways must part. Glaumvör reminds Vingi of the sanctity due to a guest and he swears that there is no deception. Kostbera and Högni say farewell to each other and the men row away.
As the brothers and their companions arrive at Atli's door, Vingi admits to his treachery and is promptly slain. Atli then attacks the five guests with a force of 30. The battle rages for hours and Guðrún joins it on the side of her brothers, throwing away her jewelry. Finally the children of Gjúki are overpowered, having slain 18 of Atli's warriors. Atli trades accusations with his wife and orders the execution of Gunnarr and Högni. Following a comical episode with Hjalli, Atli's cook, Atli has the brothers executed. Högni dies laughing while Gunnarr dies playing a harp with his toes.
Atli discusses matters with Guðrún. She tells him that things will go badly for him unless he kills her too. He tries to console her by promising precious gifts and she pretends to relent, asking Atli for a great ale-feast to commemorate her brothers. Guðrún then kills their two sons and has the unsuspecting Atli use their heads as drinking vessels and eat their roasted hearts. Later Guðrún kills Atli with the aid of Hniflungr, son of Högni. The final part of the poem consists of exchanges between Guðrún and Atli. Guðrún recalls her glorious past when she went harrying with Sigurðr and her brothers. Atli recalls his marriage proposal to Guðrún and how she was never content in their marriage, despite all their riches. In the end he asks Guðrún to give him an honorable burial and she agrees. She then attempts suicide and fails. The poem ends on a note that any man who begets such offspring as Gjúki is fortunate.
