What type of luxaries did the Indus cities have?

There is little known for certainty about the early
Harappan (Indus River) civilization because much of its artifacts are under water, and
its language has not yet been deciphered. However, such artifacts as have been
discovered indicate a very advanced and sophisticated
society.

Streets appear to have been laid out on a grid,
the earliest evidence of such an accomplishment. Private homes had two and three rooms
with showers and flush toilets which drained into a central sewer system. Some larger
homes had over a dozen rooms. At least one city had a very large pool with dressing
rooms for bathers. There is strong evidence that the people of this society sent ships
to Mesopotamia for trade which carried ivory, gold, and pearls which were traded for
wool, leather and olive oil. The picture is thus of a very affluent and advanced society
long before such societies appeared in Western Europe.
