who excited the Gauls to revolt in his favour, in the reign

PACA'TUS (Latinus Drepanius), a Latin poet and 
orator, who flourifhed in the fourth century, was a native 
of Drepanum, in Aquitania. He was in habits of inti¬ 
macy with Aufonius, who confulted him on his own 
writings, and has addreffed feveral pieces to him. When 
Theodofius the Great vifited Rome, in the year 388, after 
the defeat of Maximus, Pacatus was deputed from Gaul 
to congratulate him on his viftory. On this occafion he 
pronounced a panegyrical oration before the emperor and 
ienate, which is extant, and in the courfe of which he 
faid, that, if the elder Brutus could be permitted to re- 
’vifit the earth, the Hern republican would abjure, at the 
feet of Theodofius, his hatred of kings, and ingenuoufly 
confefs that fuch a monarch was the molt faithful guar¬ 
dian of the happinefs and dignity of the Roman people. 
Pacatus was afterwards created a proconful, and in 393 
was appointed fuperintendar.t of the imperial domain. 
The orator Symmachus addreffed feveral letters to him, 
and Sidonius Apollinaris mentioned him with applaufe. 
He was probably a Pagan. None of his poems remain ; 
his Panegyric on Theodofius was printed in 1651, fepa- 
rately, and it is contained in the Panegyrici Veteres. It 
is reckoned eloquent for the age in which it was written ; 
more charafteriled by force of expreflion and imagination 
than by tafte and purity of ftyle, and its bed paflages 
bearing fome refemblance to the manner of Tacitus.

PACCHIO'NI (Antonio), a learned phyfician and ana- 
tomift, was born at Reggio in 1644. He received his firft 
education in his native city ; and, having embraced the 
medical profeflion, he went to Rome, where he attended 
■upon the celebrated Malpighi, and was introduced by him 
to praftice. Through the recommendation of that phy¬ 
fician he fettled at Tivoli, where he praftifed with repu¬ 
tation for fix years. He was then invited to Rome, and 
was aflociated by Lancifi in his explanation of the plates 
of Euftachius. In this city he devoted himfelf to anato¬ 
mical enquiries, and was much occupied in difleftions. 
In 1701 he publifhed a work of temporary celebrity, 
“ De Duras Meningis Fabrica et Ufa;” Romae, 8vo. In 
this treatife he advanced an hypothefis concerning the muf- 
cular and contraftile nature of the dura mater, which he 
fuppofed, by means of its conneftion with the tentoria, 
to aft by alternate compreflion upon the brain and cere¬ 
bellum. In 1705 he publifhed an “ Epiftolary Diflerta- 
tion,” addreffed to Lucas Schroeckius, concerning the 
conglobate glands of the dura mater, and the lymphatics 
proceeding from them. His opinions involved him in 
controverfies with other anatomifts, and produced other 
publications of his own. In his “ Diflertationes Phyfico- 
anatomicae, novis Experiments et Lucubrationibus audlae 
et illuftratae,” Romae, 1721, 8vo. he has given his final 
notions on his favourite fubjeft, and continues to main¬ 
tain the mufcular nature and aftion of the dura mater. 
Though his opinions have not been received by later 
anatomifts, they are fupported with ingenuity, and his 
P A C 175 
enquiries contributed to a more accurate knowledge of 
the parts concerned. Pacchioni died at Rome in 1726. 
He was a member of the academies of Bologna and Sienna, 
and of the fociety Naturae Curioforum. An edition of 
all his works, printed and manufcript, with figures, was 
publilhed at Rome in 1741, 4 to. Eloy Ditt. Halleri Bibi.

PACCIAU'DI (Paolo Maria), an hiftorian and anti¬ 
quary, was born at Turin in 1710. He entered into the 
order of Theatines, and became librarian to Philip duke 
of Parma. After a ftudious and retired life, occupied 
lolely in the duties of his ftation, he died of an apoplexy 
in 1785. He was a correfpondent of the Academy of 
Infcriptions and Belles-Lettres. The works of this 
learned man are, 1. De Cultu S. Joannis Bapt. Antiqui- 
tates Chriftianae, 4to. 1735. 2. Monumenta Peloponne- 
fiaca, 2 vols. 4to. 1761. 3. Memorie de’ Gran Maeftri

Magich. —The motion or progreffion of a horfe.—The 
molt common paces, and thofe which are natural to the 
horfe, are the walk, the trot, and the gallop. There is 
likewife another pace which is acquired by horfes, called 
the amble, but which in fome appears to be almoft natural 
to them. In fome cafes it is not uncommon for horfes 
to mix their different paces, and by this means to go in a 
fort of fhuffle betwixt the walk, trot, amble, and gallop ; 
but, where the horfe has a good and proper pace, he moves 
with fteadinefs in thefe feveral modes of progreffion with¬ 
out mixing them in any degree whatever. Chambers.
