Cornwall and Devon on the Gough map

Although most of the surviving elements of Tintagel castle, built by Richard Earl of Cornwall, in the 1230s are today on the mainland it is interesting that the Gough map locates it on the island, see image below.

Perhaps, this was because the main part of the castle, the Great Hall, was located there.

That fell into ruin by 1337 which perhaps lends support to the suggestion that the map’s prototype dates from c. 1280.

The map labels Totnes as Dertesmour and refers to Brutus’s landing there. Motland appears to refer to Looe Island. A label by it is now indecipherable but may well have been referring to the legend that Joseph of Arimathea and the child Christ landed there. Celly is the Isles of Scilly.

The tribes of Europe

Europe in 526, Kossina, CC.

HB 17.

HB 17 (c. 830):
“The first man who came to Europe was Alanus, of the line of Japheth, with his three sons, whose names are Hessitio, Armenon and Negue. Hessitio had four sons, Francus, Romanus, Britto and Alemannus; Armenon had five sons, Gothus, Walagothus, Gepidus, Burgundus and Langobardus; Negue had three sons, Vandalus, Saxo, Bavarus. From Hessitio derive four peoples; the Franks, the Romans, the Alemannns and the Britons; from Armenon five, the Goths, the Walagoths, the Gepids, the Burgundians and the Langobards; from Negue four, the Bavarians, the Vandals, the Saxons and the Thuringians. These whole of Europe is divided between these nations.”

The origin for this list is the The Frankish table of Nations whose source was Tacitus’s Germania:
“In the traditional songs which form their only record of the past the Germans celebrate an earth-born god called Tuisto. His son Mannus is supposed to be the fountain-head of their race and himself to have begotten three sons who gave their names to three groups of tribes – the Ingaevones, nearest the sea; the Herminones, in the interior; and the Istaevones, who comprise all the rest. Some authorities, with the freedom of conjecture permitted by remote antiquity, assert that Tuisto had more numerous descendants and mention more tribal groups such as Marsi, Gambrivii, Suebi, and Vandilii – names which they affirm to be both genuine and ancient. The name Germania, however, is said to have been only recently applied to the country. The first people to cross the Rhine and appropriate Gallic territory, though they are known nowadays as Tungri, were at that time called German; and what was at first the name of this one tribe, not of the entire race, gradually came into general use in the wider sense. It was first applied to the whole people by the conquerors of the Gauls, to frighten them; later, all the Germans adopted it and called themselves by the new name.”

Frankish table of nations A.

The Frankish table of Nations recension A in St Gall Stiftsbibliothek (First 3rd of 9th c.):
The table appears in 7 manuscripts and provides a list of sons for the 3 brothers listed by Tacitus. The recensions vary in some degree with each other.The original table has been dated to c. 520 on the basis of the tribes listed. Note, the HB dendogram shown above differs in that the Vandals and Saxons have been moved as have the Burgundians, Langobards. Moreover, the Loringians have disappeared.
The Historia Brittonum gives Alanus’s descent in paragraph 17 and then in the next paragraph gives that of Brutus:

Legend: red (Hebrew), green (Irish), blue (Greek and Trojan), purple (British)

Nennius says of HB 17:

“I found another explanation about Brutus in the old books of our elders.”

However, that list may be reconciled with HB 18 by noting the Trojan Rhea Silvia and the Irish Fetebir both appear in gen. -47 as parents of Alanus. For this agreement of the lists to occur it needs to be noted that the actual Numa Pompilius was the Roman king succeeding Romulus and he has been conflated with two individuals: Nenne (gen. -48) and Parapilius (gen. -49). This is indicated by ByA 33:

“… Anchise m. Eneas m. Ascanius m. Parapilius m. Nenne m. Reesilue m. Alanius m. Ericonius m. Brutus …”

The Historia Regum Britanniae gives an incorrect abbreviated list: Aeneas, Ascanius, Siluius and Brutus, which is largely accepted by the genealogies. It also errs in making Siluius male whereas in reality the name is Silvia. Although the Historia Brittonum gets the gender right, it conflates her with Rhea Silvia, the mother of Romulus.

Note, Mommsen interpreted Flise of HB 18 gen. -58 as Elisa, presumably a refernce to Elishah son of Javan.[1] Although gen. -62 to -58 are missing, they may have given the ancestry of Electra, the mother of Dardanus.
