With Jarl Ragnvald, Jarl St. Magnus’ sequel in estate, and himself afterwards St. Ragnvald, who was much in Caithness and Sutherland, and seems to have held and acquired considerable estates there, begins what is practically a new Saga, which may be styled “The Story of Ragnvald, and of Sweyn” the great Viking.  Of these two we have perhaps the finest and most vividly painted pictures of the Orkneyinga Saga, full of dramatic touches, full, too, of interesting historical detail.

First, we have a portrait of the young Ragnvald as Kali Kolson in his youth at Agdir in Norway, with his mother Gunnhild, sister of Jarl St. Magnus Erlend’s son, and his shrewd old father Kol.  We are told that Kali was “the most hopeful man” or man of promise, “of middle stature, fine of limb, with light brown hair”; how he “had many friends, and was a more proper man both in body and mind than most of the other men of his time, a good player at draughts, a facile writer of runes, and a reader of books, good at smith’s work, ski-ing, shooting, and rowing, and as skilful at song as at the harp."[9]

At the age of fifteen, he traded to Grimsby, where many Norwegians and Orkneymen came, and many from the Hebrides; and here he met Harald Gillikrist, who became his firm friend, and confided in him alone that he, Harald, was the son of King Magnus Barelegs, asking how he would be received by King Sigurd of Norway, and obtaining the diplomatic reply that he would be well received by the king, if others did not spoil his welcome.  Then Kali returns to Bergen in 1116, about the time of Jarl Magnus’ murder by his cousin Jarl Hakon, and after a friendship and a feud with Jon Peterson, which is amicably settled by the marriage of Jon with Kali’s sister Ingirid, and of which the description well illustrates the manners and law of the times, is made Jarl Ragnvald of Orkney by King Sigurd; and on that king’s death in 1126 he is confirmed in the title by his friend King Harald, for whom he fought in the battle for the throne at Floruvoe near Bergen, when King Magnus was captured, maimed, and deposed by Harald in 1135.

Jarl Paul, however, refused to part with half the isles; and, acting on Kol’s advice, Jarl Ragnvald’s messengers apply for aid in obtaining it to Frakark and her grandson Olvir Rosta in Kildonan, and offer them Paul’s half share if they will help Ragnvald to secure his half.  Frakark, having previously arranged that her niece Margret, the daughter of Earl Hakon and Helga, should marry Earl Maddad of Athole, second cousin to David I, as his second wife, thought that Orkney might be had, with half the jarldom and all Caithness, for Margret’s son Harold Maddadson, then an infant in arms.

Ragnvald and Frakark then made common cause.[10] But in 1136 Paul defeated Frakark’s ships in a sea fight off Tankerness in Deer Sound in Orkney, and immediately afterwards seized Jarl Ragnvald’s fleet in Yell Sound in Shetland, though Ragnvald and his men escaped to Norway in merchant vessels, to return later on.[11]
