ANCIENT GREEK PAINTING.


A lecture on ancient Greek painting was lately delivered by Professor
C.T. Newton, C.B., at University College, London. The lecturer began by
reminding his audience of the course of lectures on Greek sculpture,
from the earliest times to the Roman period, which he completed this
year. The main epochs in the history of ancient sculpture had an
intimate connection with the general history of the Greeks, with their
intellectual, political, and social development. We could not profitably
study the history of ancient sculpture except as part of the collateral
study of ancient life as a whole, nor could we get a clear idea of the
history of ancient sculpture without tracing out, so far as our
imperfect knowledge permits, the characteristics and successive stages
of ancient painting. Between these twin sister arts there had been in
all times, and especially in Greek antiquity, a close sympathy and a
reciprocal influence. The method in dealing with the history of Greek
painting in this course would be similar to that adopted in the course
on sculpture. The evidence of ancient authors as to the works and
characteristics of Greek painters would be first examined, then the
extant monuments which illustrate the history of this branch of art
would be described. In the case of painting, the extant monuments were
