With this he mingled the Attic contractions, the broader Doric, and the feebler AEolic, which often rejects its aspirate, or takes off its accent, and completed this variety by altering some letters with the licence of poetry.

Thus his measures, instead of being fetters to his sense, were always in readiness to run along with the warmth of his rapture, and even to give a further representation of his notions, in the correspondence of their sounds to what they signified.

Out of all these he has derived that harmony which makes us confess he had not only the richest head, but the finest ear in the world.

This is so great a truth, that whoever will but consult the tune of his verses, even without understanding them (with the same sort of diligence as we daily see practised in the case of Italian operas), will find more sweetness, variety, and majesty of sound, than in any other language of poetry.

The beauty of his numbers is allowed by the critics to be copied but faintly by Virgil himself, though they are so just as to ascribe it to the nature of the Latin tongue: indeed the Greek has some advantages both from the natural sound of its words, and the turn and cadence of its verse, which agree with the genius of no other language.
Virgil was very sensible of this, and used the utmost diligence in working up a more intractable language to whatsoever graces it was capable of, and, in particular, never failed to bring the sound of his line to a beautiful agreement with its sense.
