and a monarch; or a fliip and a houfe: and on this re¬ 
semblance is ter be raifed a fuperftruCture of contrarieties 
to amufe and perplex. It is ealier to find great fubjefts 
for amigmas in figures than in words, inafmuch as painting 
attracts the eyes and excites the attention to difeover the 
fenfe. The Subjects of tenigmas in painting, are to be ta¬ 
ken either from hiftory or fable : the composition here is 
a kind of metamorphofis, wherein human figures are 
changed into trees, and rivers into metals. It is effential 
to amigmas, that the hiltory or fable, under which they 
are prefented, be known to every body; otherwise it will 
be two amigmas inltead of one; the firft of the hiftory or 
fable, the Second of the fenfe in which it is to be taken. 
Another effential rule of the amigma is, that it only ad¬ 
mits of one fenfe. Every amigma which is fufeeptive of 
different interpretations, all equally natural, is So far im¬ 
perfect. What gives a kind of erudition to an aenigma, 
is the invention of figures in Situations, geftures, colours, 
fcc. authorised by paftages of the poets, the cuftoms of 
artif'ts in Statues, bairo relievos, inscriptions, and medals. 
In foreign colleges, the explication of amigmas makes a 
considerable exercife; and that one of the 1110ft difficult 
and amufing, where wit and penetration have the largeft 
field. ' 
•-ZENIGMATOGRAPHY, or vEnigmatholocy,/. 
the art of refolving or making aenigmas. 
ZENONA, a city of Liburnia, called by Pliny Civitas 
Prafini, alfo Enona, and is now called Nona; on the Adri¬ 
atic, by which it is for the greater part Surrounded, over- 
againft the ifland Gilla, from which it is diftant four miles 
to the weft. Lat. 2S.0. Ion. 16.0. E. 
ZENUS, now the Inn, a river of Germany, which, riling 
in the country of the Grifons, out of the Alps, in the 
diltrifl called Gottes-huus-punt, runs throught the Gri¬ 
fons, the county of Tyrol, the duchy of Eavaria, and 
through Paftau into the Danube. 
jEnus, i 5 Enos, or jEnum, anciently a town of Thrace, 
fituate on the eaft mouth of the Hebrus, which has two 
mouths; and faid to be built by the Cumeans. Now Eno. 
ZENITHOLOG 1 US, /. in poetry, a verfe of two dac¬ 
tyls and three trocluri; as, Pralia diraplaccnt trucijuvcntce. 
ZEOI. 1 ZE INSULZE, now Ifole di Lipari, Seven illands, 
Situated between Sicily and Italy, So called from ZEolus, 
who reigned there about the time of the Trojan war. 
ZEOLIC, adj. in a general fenfe, denotes Something be¬ 
longing to ZEolis. 
ZEolic, or ZEolian, in grammar, denotes one of the 
five dialefts of the Greek tongue. It was firft ufed in 
Boeotia; whence it palled into ZEolin, and was that which 
Sappho and Alcaeus wrote in. The ZEolic dial^ft gene¬ 
rally throws out the afpirate or ffiarp Spirit, and agrees in 
So many things with the Doric dialed, that the two are 
ufually confounded together. 
ZEolic Verse, in profody, a verfe confiding of an 
iambus, or Spondee ; then of two anapefts, Separated by a 
long Syllable ; and, laftly, of another Syllable. Such as 
0 Jie.tlifcfi conditor orbis. This is otherwife called culogic 
verfe; and, from the chief poets who ufed it, Archilochian 
and Pindaric. 
Z£OLIPILE,yi in hydraulics, is a hollow ball of metjl, 
generally ufed in courfes of experimental philofophy, in 
order to demonstrate the poffibility of converting water 
into an elaftic (team or vapour bv heat. The inftrument, 
therefore, confifts of a (lender neck, or pipe, having a 
narrow orifice inferted into the bail by means of a Shoul¬ 
dered Screw. This pipe being taken out, the ball is fill¬ 
ed almoft full of water, and, the pipe being again Screwed 
in, the ball is placed on a pan of kindled Charcoal, where 
it is well heated, and there ilFues from the orifice a vapour, 
with prodigious violence and great nolle, which continues 
till all the included water is discharged. The Itronger the 
hre is, the more elaftic and violent will be the fleam; but 
care mult be taken that the Small orifice of the pipe be not, 
bv any accident, Stopped up; becaufe the inftrument 
would in that cafe infallibly bui lt in piece-, w ith fuch vio¬ 
lence as may greatly endanger the lives of the perfons near 
it. Another way of introducing the water is to heat the 
ball red-hot when empty, which will drive out almoft all 
the air; and then by Suddenly immerging it in water, the 
prelftire of the atmofphere will force in the fluid till it is 
nearly full. Des Cartes and others have ufed this inftru¬ 
ment to account for the natural caufe and generation of 
the wind : and hence it was Called Aiolopila, q. d. pila yEoli, 
the ball of ZEolus or of the god of the winds. 
ZEOLIS, orZEoi.iA, the ancient name of a country of 
the Hither Alia, fettled by colonies of ZEolian Greeks. 
Taken at large, it comprehends all Troas, and the coaft: 
of the Hellefpont to the Propontis, becaufe in thofe parts 
there are Several ZEolian colonies: more ftriftly, it is Situ¬ 
ated between Troas to the north, and Ionia to the South. 
The people are called ZEoles or ZEolii. 
ZEOL 1 UM MARE, a part of the ZEgean Sea, waffling’ 
ZEolis; called alfo Myfium, from Mylia. It is now call¬ 
ed Golfo di Smyrna. 
ZEOLUS, in heathen mythology, the god of the winds, 
was faid to be the Son of Jupiter by Acafta, or Sigelia, the 
daughter of Hippotus : or, according to others, the fon of 
Hippotus by Meneclea, daughter of Hyllus king of Lipa- 
ra. He dwelt in the filand Strongyle, now called Strom- 
bolo, one of the feven illands called ZEolian, from their 
being under the dominion of ZEolus. Others fay, that 
his refidence was at Regium, in Italy; and others again 
place him in the ifland Lipara. He is represented as hav¬ 
ing authority over the winds, which he held enchained in a 
vaft cavern, to prevent their continuing the devaftations 
they had been guilty of before they were put under his 
direction. Mythologifts explain the original of thefe fa¬ 
bles, by faying, that he was a wife and good prince; and, 
being (killed in aftronomy, was able, by the flux and reflux 
of the tides, and the nature of the volcano in the ifland of 
Strongyle, to foretel ftorms and tempefts. 
ZEON,yi a Greek word, properly Signifying the age or 
duration of any thing. 
ZEon, among the followers of Plato, was ufed to figni- 
fy any virtue, attribute, or perfection : hence they repre¬ 
sented the deity as an alfemblage of all poffible aeons; and 
called him pleroma, a Greek term ftgnifyingfullnfs. The 
Valentinians, who, in the firft ages of the church, blended 
tire conceits of the Jewilh cabalifts, the Platonifts, and 
the Chaldean philofophers, with the fimplicity of the 
Chriltian doctrine, invented a kind of Theogony, or Ge¬ 
nealogy of Gods (not unlike that of Hefiod), whom they 
called by Several glorious names, and all by the general 
appellation of ZEons: among which they reckoned 
Life ; Aofosj Word ; Movo/am?, Only-begotten ; nXiipw/aa, Full- 
ncfs\ and many other divine powers and emanations, 
amounting in number to thirty : which they fancied to be 
fucceflively derived from one another; and all from felf- 
originated deity, named Bythus , i. e. profound or unfathom¬ 
able ; whom they likewife called The mof high and ineffable 
Father. See Valentinians. 
ZEORA,/! [from amvft*/, to lift up, tofufpend on-high. J 
A Species of exercife ufed by the ancients for geftation, 
and of which Aetius gives the following account: 
Geftation, while it exercil'es the body and limbs, ftill 
they Seem, to be at reft. Of the motion there are feveral 
kinds, ill, Swinging in a hammock, which, at the de¬ 
cline of a fever, is beneficial, idly, Being carried in a 
litter, in which the patient either fits or lies along. It is 
ufeful when the gout, ftone, and fuch other diforders, at¬ 
tend, that do not admit of violent motions, jdly, Riding 
in a chariot, which is of Service in 1110ft chronical disor¬ 
ders, efpecially before the ftronger exercife can be admit¬ 
ted. 4thly, Sailing in a boat or Ihip. This produces va¬ 
rious effects, according to the different agitation of the. 
waters, and in many tedious chronical diforders proves, 
efficacious beyond what is obferved from the 'moll Ikilful 
adminifl ration of drugs, Thefe are inffances of pallive 
exercife, and are ufeful, particularly when adtive exercife 
would be improper, or impracticable. Afdepiades was
