Acci, in Ancient Geography, a town of Tarraconensis, formerly called Adili; supposed to be Guadix, to the east of the city of Granada in Spain, at the foot of a mountain, near the source of the rivulet Guadalantin; now greatly decayed. It is the Colonia Accitana Gemella, and was of some repute among the Roman colonies. The people were called Gemellenses, because the colony consisted of colonists from the third and sixth legions.
