"Qui, quid sit pulcrum, quid turpe, quid utile, quid non,
Planius ac melius Chrysippo et Crantore dicit:"
["Who tells us what is good, what evil, what useful, what not, more
clearly and better than Chrysippus and Crantor?"
—Horace, Ep., i. 2, 3.]
and as this other says,
"A quo, ceu fonte perenni,
Vatum Pieriis ora rigantur aquis"
["From which, as from a perennial spring, the lips of the poets
are moistened by Pierian waters."—Ovid, Amoy., iii. 9, 25.]
and the other,
"Adde Heliconiadum comites, quorum unus Homerus
Sceptra potitus;"
["Add the companions of the Muses, whose sceptre Homer has solely
obtained."—Lucretius, iii. 1050.]
and the other:
"Cujusque ex ore profusos
Omnis posteritas latices in carmina duxit,
Amnemque in tenues ausa est deducere rivos.
Unius foecunda bonis."
