The Gesta Danorum (Books I-IX) on Wigg
The Danish History, > Book Two
attestation: A youth named Wigg gave Rolf the nickname 'Krage' (tree-trunk) in jest at his towering stature
"A youth named Wigg, scanning with attentive eye the bodily size of Rolf, and smitten with great wonder thereat, proceeded to inquire in jest who was that "Krage""
attestation: Wigg vowed to avenge Rolf if he should perish by the sword
"he promised, uttering a strict vow, that, if it befell Rolf to perish by the sword, he would himself take vengeance on his slayers"
attestation: Wigg killed Hiartuar by tricking him into offering a sword hilt-first (Rolf's custom), then driving the point through him
"Wigg refused the point, and asked for the hilt, saying first that this had been Rolf's custom when he handed forth a sword to his soldiers"
attestation: Wigg accepted his own death joyfully after fulfilling his vow to avenge Rolf
"he exposed his body to them eagerly and exultantly, shouting that he felt more joy in the slaughter of the tyrant than bitterness at his own"
