This chapter presents a case study of one myth that we have from pictorial sources in the Viking Age, from poems almost certainly composed in the Viking Age, and from thirteenth-century sources, namely the encounter between the god Þórr (Thor) and his cosmic enemy, the World serpent, a beast that encircles the earth, in the deep sea. In this myth, Þórr fishes up the serpent, and depending on the variant, Þórr may or may not kill the serpent. I present and analyze the texts in more or less chronological order, from the older skalds through the Eddic poem Hymiskviða, through Snorri Sturluson in Edda, and compare the texts to the rock carvings that portray the myth. I argue that the issue of the death or survival of the serpent is less important than the simple fact that Þórr had the serpent on his hook.

Abstract Hemipelagic green clayey shales and thin muddy turbidites accumulated in a deep sea environment below the CCD in the Skole Basin, a part of the Outer Carpathian realm, during the Middle Cenomanian. The hemipelagites contain numerous radiolarians, associated with deep-water agglutinated foraminifera. These sediments accumulated under mesotrophic conditions with limited oxygen concentration. Short-term periodic anoxia also occurred during that time. Muddy turbidity currents caused deposition of siliciclastic and biogenic material, including calcareous foramini-fers and numerous sponge spicules. The preservation and diversity of the spicules suggests that they originate from disarticulation of moderately diversified sponge assemblages, which lived predominantly in the neritic-bathyal zone. Analyses of radiolarian ecological groups and pellets reflect the water column properties during the sedimentation of green shales. At that time, surface and also intermediate waters were oxygenated enough and sufficiently rich in nutri-ents to enable plankton production. Numerous, uncompacted pellets with nearly pristine radiolarian skeletons inside show that pelletization was the main factor of radiolarian flux into the deep basin floor. Partly dissolved skeletons indicate that waters in the Skole Basin were undersaturated in relation to silica content. Oxygen content might have been depleted in the deeper part of the water column causing periodic anoxic conditions which prevent rapid bacterial degra-dation of the pellets during their fall to the sea floor.
