Per Pinguia culta
In mare purpureum v[=i]olent[=i]or [=i]nflu[=i]t amn[=i]s._

The former Line strikes the Ear with _Mysus_ and _Caicus_; here you
have _Auratus_, _Eridanus_, and _Alius_. Then an Alliteration, _Per
Pinguia_, and at last the whole Passage rolls on in a Dactyl Line, and
rushes into the Sea with an _Assultus_ of the Vowel _i_, repeated five
times in three Words.

"--_Violentior influit amnis._

The following Line tours into the Skies with the highest Mountain in
_Italy_.

"--_Gaudetque nivali
Vertice se attollens pater Appeninus, ad auras._--

This falls down as low as the deepest Valley.

"_Saxa per, & scopulos, & depressas convalles._

In short there is nothing in Nature that _Virgil's_ Verse does not
convey to the _Ear_, and the _Eye_; so that this Subject is
inexhaustible, and must be left to every one's particular Observation.

The learned _Morhophius_ has a Passage relating to this Matter which
comes in too properly here to be omitted.

"Solent Carminibus suae esse a Numeris Veneres, & certa quaedam
Artificia, quae mirifice ornant versum, quales apud Virgilium, mirum
numeri Poetici Observatorem, frequenter occurrunt, e.g. cum versus
terminantur Monosyllabis, ut: _procumbit humi bos: nascetur
ridiculus mus_. Vel cum Spondaei multi adhibentur, ut; _media agmina
circumspexit: Illi inter sese magna vi brachia tollunt_. Aut cum
Dactyli & Spondaei ita miscentur, ut REI NATURAM EXPRIMANT, ut cum de
turri ruente ait:

"--_Convellimus altis
Sedibus; impulimusq;, ea lapsa repente_ ruinam
_Cum sonitu trahit_.--

"Talia infinita apud Virgilium habentur quae homo in iis non
exercitatus contemnat, doctus vero & prudens admiretur.
_Polyhist._

There is also a Remark of the judicious _Columna_ on a celebrated Line
in _Virgil_, which is very much to the present Purpose.

_Unus Homo Nobis Cunctando Restituit Rem._]

Virgilius de eodem loquens AEneid l. 6. integrum hoc carmen sumpsit,
ita tamen, ut _spondeorum tarditate Fabii moram referret_,

--tu Maximus ille es,
Unus, qui nobis cunctando restituis rem.
_Enn. Frag._

Sept. 21, 1736,

_I am_, SIR, _&c._
