lus was bringing
out a tragedy, painted a scene, and left a commentary about it. This led
Democritus and Anaxagoras to write on the same subject, showing how,
given a centre in a definite place, the lines should naturally
correspond with due regard to the point of sight and the divergence of
the visual rays, so that by this deception a faithful representation of
the appearance of buildings might be given in painted scenery, and so
that, though all is drawn on a vertical flat facade, some parts may seem
to be withdrawing into the background, and others to be standing out in
front.

12. Afterwards Silenus published a book on the proportions of Doric
structures; Theodorus, on the Doric temple of Juno which is in Samos;
Chersiphron and Metagenes, on the Ionic temple at Ephesus which is
Diana's; Pytheos, on the Ionic fane of Minerva which is at Priene;
Ictinus and Carpion, on the Doric temple of Minerva which is on the
acropolis of Athens; Theodorus the Phocian, on the Round Building which
is at Delphi; Philo, on the proportions of temples, and on the naval
arsenal which was[9] at the port of Peiraeus; Hermogenes, on the Ionic
temple of Diana which is at Magnesia, a pseudodipteral, and on that of
Father Bacchus at Teos, a monopteral; Arcesius, on the Corinthian
proportions, and on the Ionic temple of Aesculapius at Tralles, which it
is said that he built with his own hands; on the Mausoleum, Satyrus and
Pytheos who were favoured with the greatest and highest good fortune.

13. For men whose artistic talents are believed to have won them the
highest renown for all time, and laurels forever green, devised and
executed works of supreme excellence in this building. The decoration
and perfection of the different facades were undertaken by different
artists in emulation with each other: Leochares, Bryaxis, Scopas,
Praxiteles, and, as some think, Timotheus; and the distinguished
excellence of their art made that building famous among the seven
wonders of the world.

14. Then, too, many less celebrated men have written treatises on the
laws of symmetry, such as Nexaris, Theocydes, Demophilus, Pollis,
Leonidas, Silanion, Melampus, Sarnacus, and Euphranor; others again on
machinery, such as Diades, Archytas, Archimedes, Ctesibius, Nymphodorus,
Philo of Byzantium, Diphilus, Democles, Charias, Polyidus, Pyrrus, and
Agesistratus. From their commentaries I have gathered what I saw was
useful for the present
