Anatomy, a pair of nerves, which, arising from the medulla in the vertebrae of the neck, ascend, and enter the skull, and pass out of it again with the par vagum, wrapped up in the same common integument, and after quitting them, are distributed into the muscles of the neck and shoulders. See Anatomy.

Accessory, among painters, an epithet given to such parts of a history-piece as serve chiefly for ornament, and might have been wholly left out: such as vases, armour, &c.

Acci, in Ancient Geography, a town of Tarracoensis, formerly called Acti; 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.

Acciaioli, Donato, a native of Florence, was born in 1428, and was famous for his learning and the honourable employments which he held. He wrote, a Latin translation of some Plutarch's Lives; Commentaries on Aristotle's Ethics and Politics; and the Lives of Hannibal, of Scipio, and of Charlemagne. He was sent to France by the Florentines, to solicit aid from Louis XI. against Pope Sixtus IV.; but on his journey died at Milan in 1478; his body was carried to Florence, and buried in the church of the Carthusians at the public expense. The small fortune he left his children is a proof of his probity and disinterestedness. His daughters, like those of Aridides, were portioned by his fellow-citizens, as an acknowledgement of his services. His funeral eulogium was spoken by Christopher Landini; and an elegant epitaph, by Politian, was inscribed on his tomb.
