Note 28 — Chapter II
William P. (William Purdie) Dickson translation
The camp of the Cantabrian legion may have been at the place Pisoraca (Herrera on the Pisuerga, between Palencia and Santander), which alone is named on inscriptions of Tiberius and of Nero, and that as starting point of an imperial road (C. I. L. ii. 4883, 4884), just as the Asturian camp was at Leon. Augustobriga also (to the west of Saragossa) and Complutum (Alcalá de Henares to the north of Madrid) must have been centres of imperial roads, not on account of their urban importance, but as places of encampment for troops.
