From A Notebook

The period 400-600 AD when Ireland is still half-legendary. . .

Feltria, Tridentum.

Narbonensis. Divine names.

Alpine gloss: daculum ‘sword’. Sicel (a people of Sicily) gloss: δαγκλον ‘Latin falx => Eng. sickle’.

Interesting because of the possibility it is a dialectical variant. . .

Could the epithet of this legendary hero be related. . .

Some of general interest for their possible links to Britain.

Could this name be linked to the Hispanic name Toletum, a town of the Carpetani tribe? No further comment, but this is an interesting suggestion from an old notebook.
