Indus Valley cities, such as the plan
of Mohenjo-Daro above, show advanced planning to produce the grid pattern of the
streets and buildings. The streets include unprecedented covered sewage canals leading
from buildings and intricate water works including wells and baths.
Dice
and other game pieces are found regularly around the Indus Valley, used for
gaming and commonly made out of ivory. Examples found at Harappa and
Mohenjo-Daro show three common marking systems- numbers 1-3 along with
longitudinal marks, numbers 1-6 in random pattern, and one artifact with the modern
number arrangement.
The
people of the Harappan civilization were expert craftsmen; one such craft is
bead-making. The beads were made of all types of semi-precious materials such
as carnelian, agate, amethyst, turquoise, lapis lazuli;
they were commonly used in trade with other civilizations in the Old World.
Trade
of the Indus Valley was more developed than previously thought, partaking in
land and maritime trade among other societies and internally. Remains of boats
have been discovered that were used for seafaring trade. Other evidences are the
stamp seals that accompanied goods and models of wagons like the one shown above.
