Arriaca

ARRI´ACA (It. Ant. pp. 436, 438) or CARACCA (Κάραιεκα, Ptol. 2.6.57; Geog. Rav. 4.44), a town of the Carpetani, in Hispania Tarraconensis, on the high road from Emerita to Caesaraugusta, 22 M. P. NE. of Complutum (Alcala/). The distance identifies it with Guadalajara, on the Henares, where the bridge across the river is built on Roman foundations. As to the variation in the name, it is said that one MS. of the Itinerary has the form Caraca. (Ukert, 1.2. p. 429.)
