DICALEDONES (?)

SOURCE

- Ammianus Marcellinus XXVIII, 8, 4 : DICALYDONAS (acc. pl.) 
(Also relevant are the names given in Greek for the 'Oceanus Duecaledonius' by Ptolemy and Marcian : see Chapter II, P- 44)

DERIVATION. The basis of the name is as for the Calidonii. The prefix di- (= due- in the ocean name) implies 'two', and points to the name being an artificial Latin désignation, that is, our form is not a latinisation of an original Celtic name and may not have had a basis in native usage. Rhys (1904) 297-98 suggested that the name indicated a 'twin people', perhaps consisting of the Vacomagi and Calidonii proper, but Watson CPNS 20 thinks them more the 'double Caledonians' from their position astride the Grampians.

IDENTIFICATION. One of two divisions of the Picts; since the Verturiones occupied the region later known as *Fortriu (gen. Fortrenn), the Dicaledones were presumably the more northerly group.

L'explication est un peu hésitante, mais s'oriente sur un doublet du nom de peuple CALEDONES, soit pour désigner une partie de ce peuple, soit un peuple voisin ou apparenté. Celui des VACOMAGI a été proposé.
Rivet et Smith proposent que les DICALEDONES représentaient le groupe le plus septentrional des CALEDONES.
