ACCI, a town of Tarraconensis, (Pliny, Ptolemy;) formerly called Atti, supposed to be Guadix, to the east of the city of Granada, at the foot of a mountain, near the source of the rivulet Guadalantín. Now greatly decayed. It is the Colonia Aecitana Gemella, (coins); and was of some repute among the Roman colonies. The people were called Gemellenfes, because the colony consisted of colonists from the third and sixth legions.
