But we discover the same bond of hospitality between Thor and Egil. According to Hymerskvida it is in Egil's house, according to Gylfaginning in the house in which Thjalfe is fostered, where the accident to one of Thor's goats happens. In one of the sources the youth whom Thor takes as a ransom is called simply Egil's child; in the other he is called Thjalfe. Two different mythic sources show that Thjalfe was a waif, adopted in Egil's house, and consequently not a real brother but a foster-brother of Svipdag and Ull. One source is Fornaldersaga (iii. 241), where it is stated that Groa in a _flædarmál_ found a little boy and reared him together with her own son. _Flædarmál_ is a place which a part of the time is flooded with water and a part of the time lies dry. The other source is the Longobard saga, in which the mythological Egil reappears as Agelmund, the first king of the Longobardians who emigrated from Scandinavia (_Origo Longob._, Paulus Diac., 14, 15; cp. No. 112). Agelmund, it is said, had a foster-son, Lamicho (_Origo Longob._), or Lamissio (Paulus Diac.), whom he found in a dam and took home out of pity. Thus in the one place it is a woman who bears the name of the archer Orvandel's wife, in the other it is the archer Egil himself, who adopts as foster-son a child found in a dam or in a place filled with water. Paulus Diaconus says that the lad received the name Lamissio to commemorate this circumstance, "since he was fished up out of a dam or dyke," which in their (the Longobardian) language is called _lama_ (cp. _lehm_, mud.) The name Thjalfe (_thjálfi_) thus suggests a similar idea. As Vigfusson has already pointed out, it is connected with the English delve, a dyke; with the Anglo-Saxon _delfan_; the Dutch _delven_, to work the ground with a spade, to dig. The circumstances under which the lad was found presaged his future. In the mythology he fells the clay-giant, _Mökkr-kalfi_ (Younger Edda, i. 272-274). In the migration saga he is the discoverer of land and circumnavigates islands (Korm., 19, 3; Younger Edda, i. 496), and there he conquers giants (Harbards-ljod, 39) in order to make the lands inhabitable for immigrants. In the appendix to the Gotland law he appears as Thjelvar, who lands in Gotland, liberates the island from trolls by carrying fire, colonises it and becomes the progenitor of a host of emigrants, who settle in southern countries. In Paulus Diaconus he grows up to be a powerful hero; in the mythology he develops into the Asa-god Thor's brave helper, who participates in his and the great archer's adventures on the Elivagar and in Jotunheim. Paulus (ch. 15) says that when Agelmund once came with his Longobardians to a river, "amazons" wanted to hinder him from crossing it. Then Lamissio fought, swimming in the river, with the bravest one of the amazons, and killed her. In the mythology Egil himself fights with the giantess Sela, mentioned in Saxo as an amazon; _piraticis exercita rebus ac bellici perita muneris_ (_Hist._, 138), while Thjalfe combats with giantesses on Hlessey (Harbardslj., 39), and at the side of Thor and the archer he fights his way through the river waves, in which giantesses try to drown him (Thorsdrapa). It is evident that Paulus Diaconus' accounts of Agelmund and Lamissio are nothing but echoes related as history of the myths concerning Egil and Thjalfe, of which the Norse records fortunately have preserved valuable fragments.
