killed every day for one Persian king’s banquets, though most of the
meat went to soldiers outside the palace, not the guests.
In their writings, Herodotus and Xenophon suggest that music
was part of the cultural life of the Persian royalty and nobility. Musi-
cal instruments were played in Persia and neighboring lands before
the rise of the Achaemenids, and included different styles of flutes
and stringed instruments.
aChaemenid SCienCe and teChnology
The ancient Persians learned from the cultures around them, bor-
rowing ideas and at times improving on them. Astronomy, the study
of the movement of the stars and planets, was blended with astrol-
ogy—using the position of the planets to predict the future. The
Babylonians began recording the movement of the moon and planets
around 700 b.c.e., and they remained the key astronomers under
Persian rule.
Tracking the movement of the sun and moon helped astrono-
mers create calendars. The Persian calendar of the Achaemenids had
12 months, and they also used a second calendar based on Zoroas-
trian teachings. A later version of this Avestan calendar used the
names of gods and holy items, not numbers, to mark the different
days in the month.
In technology, the Persians focused on improving irrigation.
These included underground water channels called qanats. The
Achaemenids also built large dams to control the flow of water for
human use. These dams were made of soil and stone and helped hold
in the heavy rains that fell during certain times of the year, saving the
water for irrigation.
Warfare also sparked new engineering feats. In The Histories,
Herodotus described how Xerxes built one of the earliest known
pontoon bridges. This kind of bridge uses small boats or other float-
ing devices to hold up a roadway that carries traffic over water.
Herodotus said the Persians used more than 600 boats to build two
bridges. It had thick cables strung over the boats and wooden logs
over the cables. Walls on the side of bridge were put up “so that the
baggage animals and horses might not see the sea beneath them and
take fright.”
Dam Discovery
In 2007, a team of Japa-
nese and Iranian archae-
ologists working in Iran
announced the discovery
of a soil dam dating back
to Achaemenid times.
Outer walls of stone
covered the dam, though
only part of the stone-
work and the soil itself
still remain. Mohsen
Zeidi, head of the team,
described to report-
ers (as reported by the
Cultural Heritage News
Agency) how a canal
22 miles long “was con-
structed from the Polvar
River to this dam . . . in
order to direct part of the
extra waters left by the
seasonal flooding toward
the reservoir of the dam
to supply water. . . .” Soil
dams of this construction
are still used today in
some dry areas of Iran.
