Few biographical facts are known about Þórarinn loftunga ‘Praise-tongue’ (Þloft). In introducing Þórarinn’s service to King Knútr inn ríki Sveinsson (Cnut the Great), Snorri Sturluson (ÍF 27, 307; cf. ÓH 1941, I, 473) records in general terms that he was an Icelander and a great poet (skáld mikit) who had spent a great deal of time with kings and other chieftains. Knýtl (ÍF 35, 124) gives a similar portrait, and adds that Þórarinn was gamall ‘old’ when he first came to Knútr. However, all of Þórarinn’s extant poetry derives from his service to Knútr and his son Sveinn, and these are the only monarchs for whom Þórarinn is recorded as a poet in Skáldatal (SnE 1848-87, III, 258, 267). Þorm Lv 10/1-2 also refers to Knútr rewarding Þórarinn with gold over a long period (for the anecdote in which it is quoted see ÓHLeg 1982, 124-8; ÓH 1941, II, 799-804), and his pre-Knútr career must remain hypothetical. Parts of three poems are preserved: Hǫfuðlausn (Hfl) and Tøgdrápa (Tøgdr) for Knútr, and Glælognskviða (Glækv) for Sveinn, probably composed in this order, and between c. 1027 and 1034; for circumstances of composition and preservation see individual Introductions below. The evidence of the poems suggests that Þórarinn entered Knútr’s service in either England or Denmark, accompanied him on his journey to Norway in 1028, and after 1030 remained at Sveinn’s court in Norway at least until c. 1032. For previous discussions of Þórarinn’s career see LH I, 601-3, Malcolm (1993), and Townend (2005, 256-7).
