Nor doth Thamyras break out into poetic raptures upon any other score; nor, by Jove, Euxodus, Aristarchus, or Archimedes. And when the lovers of the art of painting are so enamoured with the charmingness of their own performances, that Nicias, as he was drawing the Evocation of Ghosts in Homer, often asked his servants whether he had dined or no, and when King Ptolemy had sent him threescore talents for his piece, after it was finished, he neither would accept the money nor part with his work; what and how great satisfactions may we then suppose to have been reaped from geometry and astronomy by Euclid when he wrote his Dioptrics, by Philippus when he had perfected his demonstration of the figure of the moon, by Archimedes when with the help of a certain angle he had found the sun's diameter to make the same part of the largest circle that that angle made of four right angles, and by Apollonius and Aristarchus who were the inventors of some other things of the like nature? The bare contemplating and comprehending of all these now engender in the learners both unspeakable delights and a marvellous height of spirit. And it doth in no wise beseem me, by comparing with these the fulsome debauchees of victualling-houses and stews, to contaminate Helicon and the Muses,-- Where swain his flock ne'er fed, Nor tree by hatchet bled.

And though a voluptuous temper of mind be naturally erratic and precipitate, yet never any yet sacrificed an ox for joy that he had gained his will of his mistress; nor did any ever wish to die immediately, might he but once satiate himself with the costly dishes and comfits at the table of his prince. But now Eudoxus wished he might stand by the sun, and inform himself of the figure, magnitude, and beauty of that luminary, though he were, like Phaethon, consumed by it. And Pythagoras offered an ox in sacrifice for having completed the lines of a certain geometric diagram; as Apollodotus tells us, When the famed lines Pythagoras devised, For which a splendid ox he sacrificed.
