more fully and expediently, and, trusting to whom we are 
prepared to strike out something new. Thus adhering 
to the principles which I found in those of their works 
adapted to my purpose, I have endeavoured to advance 
further. Agatharcus, at the time when Æschylus taught 
at Athens the rules of tragic poetry, was the first who 
contrived scenery, upon which subject he left a treatise. 
This led Democritus and Anaxagoras, who wrote there¬ 
on, to explain how the points of sight and distance 
ought to guide the lines, as in nature, to a centre; so 
that by means of pictorial deception, the real appearances 
of buildings appear on the scene, which, painted on 
a flat vertical surface, seem, nevertheless, to advance and

symmetry of Doric buildings; Theodorus, on the Doric 
temple of Jupiter in Samos; Ctesiphon and Metagenes, 
on that of the lonic order in the temple of Diana at 
Ephesus. Phileos wrote a volume on the lonic temple 
of Minerva at Priene, and Ictinus and Carpion on the 
Doric temple of Minerva at Athens, on the Acropolis; 
Theodorus Phoceus on the vaulted temple at Delphi; 
Philo on the symmetry of temples, and on the arsenal at 
the Piræus; Hermogenes on the lonic pseudodipteral 
temple at Magnesia, and the monopteral one of Father 
Bacchus at Teos. Argelius wrote on the proportions 
of buildings of the Corinthian order, and on the lonic 
temple of Asculapius at Tralles, which he is said to 
have built ; Satyrus and Phyteus, who were extremely 
fortunate, on the Mausoleum, to which some contributed 
their exertions whose talents have been admired in all 
ages, and who have gained lasting reputation. Each 
front was assigned to a separate artist, to ornament
