Alderga and Aldergamouth

Aldergamouth was a harbor:

• located three poles, or a half tide (c. 3 hours?), south of Medeasblik (8a)
• where former sea king Sterik (uncle of sea warriors Tunis and Inka) had taken his retirement (8b)
• at the southern head of which stood the Treasureburg, a stone building where a variety of shells, horns, weapons, and clothes were kept, brought home from distant lands by the steersmen (13i)

Alderga was a lake:

• located a quarter [FJARDÉL] (of a day?) from the Aldergamouth (13i);
• surrounded by richly ornamented barns, houses, and gardens (13i);
• in which an operational fleet was docked, with flags of many colors (13i);
• connected to a narrow mouth (ÉGA.MVDA) into the sea by a dug canal, which flowed past the burg Forana. This canal was the way out for the fleet, and the Flee was the way in (through the Aldergamouth). On both sides of the canal were beautiful houses, brightly colored, with gardens surrounded by evergreen hedges (13i). This canal was blocked by sand and lost due to the big flood of ca. 305 BCE (14a);
• where poor Saxmen came with their wives to search in the soil for golden and other jewelry after the big flood of ca. 305 BCE (14b);
• where some of the Ionians settled, as they believed themselves to have sprung from the folk of the Alderga (14c);
• where the best warships were built of hard oak which never rots (16b);
• which was the final destination of the journeys of both Apollania (13i/16d) and Adel and Ifkia (16d).
• on the shore of which sea king Jon was born (9b);

Fragments

8a. Magyars and Finns

[050/19] The following is inscribed on the Treasureburg at the Aldergamouth (ALDE.GÁ.MVDE): (...) It is located three poles, or a half tide, south of Medeasblik.

8b. Wodin and the Magus

[053/15] At the Aldergamouth (ALDER.GÁ.MVDE), a former sea king had taken his retirement. Sterik was his name, and the renown of his deeds was great. (...) Tunis and Inka were sea warriors and, at the time, they were staying in the home of their father’s brother at the Aldergamouth (ALDER.GÁ.MVDE).

9b. Jon’s Revenge

[065/20] Jon — meaning: ‘given’ — was a sea king, born at the Alderga (ALDER.GÁ), who had sailed out of the Flee Lake with a hundred and twenty-seven ships

11c. Death of the Magus

[085/20] The steersmen of Staveren and of the Alderga (ALDERGA) were eager to confront him, but the great fleet was out on a distant voyage.

13i. Apollania’s Journey

[110/15] Finally, we arrived at the Alderga[-mouth] (ALDERGA). At the southern head of the harbor stands the Treasureburg, a stone building where a variety of shells, horns, weapons, and clothes are kept, brought home from distant lands by the steersmen. A quarter of a day from there is the Alderga (ALDERGA), a great lake surrounded by barns, houses, and gardens — all richly ornamented. In the lake, a great fleet lay ready, with flags of many colors. (...) Behind the lake, a canal had been dug, which flowed past the burg Forana, and further through a narrow mouth into the sea. This was the way out for the fleet, and the Flee was the way in. On both sides of the canal are beautiful houses, brightly colored, with gardens surrounded by evergreen hedges.

14a. Fryasland Swamped

[116/30] The canal that had run across the land from the Alderga (ALDERGÁ) had been blocked by sand and was lost.

14b. Gosa: Settlement of the Black Men

[118/20] When our lands were passable again, groups of poor Saxmen came with their wives to the regions of Staveren and the Alderga (ALDERGA) to search for golden and other jewelry in the sodden soil.

14c. A Fleet Arrives

[120/01] Some of the Ionians who believed themselves to have sprung from the folk of the Alderga (ALDERGA) went there.

16b. Friso: Alliances

[148/10] because at Staveren and along the Alderga (ALDER.GÁ) the best warships are built of hard oak which never rots.

16d. Adel and Ifkia

[157/20] Just like Apollania, they concluded their journey with a visit to Lydasburg and the Alderga (ALDER.GÁ).

Interpretations

Ottema translated as 'Alderga' and 'Alde(r)gamude'. He did not speculate about where they may have been located, neither in a foortone, nor in “Geschiedkundige Aantekeningen en Ophelderingen” (1878).

Overwijn translated as 'Alde(r)ga' and 'Aldegamond(e)'. To the fragment of ch. 8a he noted in his 1941 edition (p.53): "Ouddorp (Alderga) near Alkmaar".

Jensma translated as 'Oudegouw' and 'Oudegouwemond' and located both at Enkhuizen. This is remarkable, since fragment 13i states that they were separated by a quarter of an hour (?) [a 'FJARDÉL']. Also, fragment 8a states that Aldergamouth was located three poles, or a half tide (3 hours?) south of Medeasblik, whereas Enkuizen is rather (south-) eastward of Medemblik (assuming the latter is located where once Medeasblik was).

Initially translating FJARDÉL as 'quarter of an hour', at later consideration (25-3-2023) Ott thinks that it will rather have been a quarter of a day or of twenty-four hours. His provisional interpretation is that the Aldergamouth with its Treasureburg must have been located approximately between what are now Hoorn and Wijdenes; that lake Alderga will have been approximately where later the Waerdt (now Heerhugowaard) or the Schermer (or the Wogmeer?) was. The canal from Alderga, along Forana, to the sea will partly correspond to the Pettemer Vaert (also see Hoornse Vaart).
