AQUAE CA´LIDAET he position of this place is marked in the Theodosian Table by its being on the road between Augustonemetum ( Clermont) in the Auvergne and Rodumna ( Rouanne). The distance from Augustonemetum to Aquae Calidae is not given; but there is no doubt that Aquae Calidae is Vichyon the Allier, a place now frequented for its mineral waters.
D'Anville ( Notice, &c.) remarks, that De Valois confounds the Aquae Calidae with the Calentes Aquae mentioned by Sidonius Apollinaris, which are Chaudes-aigues (hot-waters) in the department of Cantal. The whole of the mountain region of the Auvergne abounds in mineral waters.
