Geitaberg is probably the place now known as Gatnip, on the east side of Scapa Bay, near Kirkwall. It is formerly stated that Játvör and her son Borgar lived at Knarrarstad, which is evidently the name for the district, while Geitaberg was the name of Borgar’s homestead. Gatnip is the highest point on that side of the bay, and thus Borgar was able to notice the barge rowed by Swein’s men as it passed up and down the Firth. Footnote 348: Magnus, in the text here, is clearly a mistake for Hákon. Footnote 349: The erection of St. Magnus’ Church was commenced apparently between the years 1136 and 1138. The remains of St. Magnus appear to have been transferred to it from Christ’s Church, in Birsay, previous to the departure of Earl Rögnvald to the Holy Land in 1152. After Earl Rögnvald’s death, in 1158, the building of the cathedral was carried on by Bishop William, until his death in 1168, after which we have no record of its progress. Footnote 350: The odal tenure of the lands in the islands was first modified by Harald Harfagri in the time of the Earl Torf Einar. Earl Sigurd Hlödverson restored the odal rights in return for the assistance of the Bœndr at the battle of Skida Myre (see Appendix). This arrangement subsisted till the imposition of the succession-dues by Earl Rögnvald, which were subsequently bought up, as here narrated. Footnote 351: Knarrarstad, as has been formerly explained, was applied to the district at the head of the Bay of Scapa. It was so called because it was the place where the merchant-ships lay—from _Knarrar_, genitive of _knörr_, a merchant-ship; and _stadr_, a stance or stead. The name is preserved in old estate-lists as _Knarstane_. In the near neighbourhood there is an ancient “broch” or “Pictish tower,” recently excavated by Mr. George Petrie. Remains of very extensive buildings have been found within and around it, evidently belonging to a secondary occupation of the tower, of later date than that of its original construction. Among the relics found in these secondary buildings there are some which correspond with relics of the later Viking period found in Scandinavia. This gives a certain amount of probability to the supposition that the ruins of this “Pictish tower” may have been occupied and utilised by Earl Rögnvald’s men, as we know that the similar tower of Mousa, in Shetland, was on different occasions, one of which is narrated in chap. xcii. of this same Saga. Footnote 352: This incident bears a remarkable similarity to that related in chap. lxvi. Footnote 353: It is curious that Cæsar has described the ancient Britons as observing in his time the same custom of shaving the lower part of the chin, and wearing the hair long on the upper lip. Footnote 354:
