==== characteristics of the Nile flooding ==== | |||
* Nile floods = predictable | |||
** Nile floods = calm | ** Nile floods = calm | ||
** floods bring silt | ** floods bring silt | ||
** flood plains = farmland, but have to be re-organized every year | ** flood plains = farmland, but have to be re-organized every year | ||
* Nile process formed Egyptian seasons of three, 4 month cycles: | |||
** ''Akhet'' = flooding | |||
*** during flooding season, farmers were displaced and could serve as laborers for large projects such as pyramids and temples | |||
*** also during flooding season, shipment of stone and other goods by boat more extensive due to wider river flow | |||
*** for example, location of the pyramids = just beyond the flood plain | |||
*** during high flood period, Nile depth = 25-33 ft deep and current was more rapid = quicker movement | |||
** ''Peret'' = growing season | |||
** ''Shemu'' = harvest season (no rain) | |||
==== appearance of the star Sirius marks flooding season ==== | |||
* the star, Sirius, announces the arrival off the floods | |||
** also known as the "dog star" | |||
** brightest start in the night sky | |||
** when Sirius appears on the horizon after disappearing during the winter (blocked from earth's view by the sun) | |||
** it marks the flooding season | |||
*** note the Greeks called the summer months the "dog days" when Sirius appears | |||
==== periods of drought ==== | |||
* larger climate patterns led to times of weakened river flow and less flooding | |||
* = periods of famine & political upheaval | |||
* most important example = end of Old Kingdom and into the Middle Kingdom | |||
==== Fayoum Oasis & Lake Moeris ==== | |||
* a basin in the desert to the west of the Nile in the upper part of Upper Egypt | |||
* Nile floods fed the lake over time | |||
** fed by the Nile and eventually connected to the Nile by Middle Kingdom pharaohs who improved irrigation in response to low flooding | |||
** Middle Kingdom c. 2300 BC the lake was widened and the canal connecting it to the Nile deepened | |||
** the lake served as reservoir for dry periods | |||
* Egypt's most important oasis | |||
* principal Neolithic site (early agriculture) | |||
** has archeological evidence of earliest farming in Egypt | |||
** site of the city Crocodilopolis (Greek name) or "Faiyum" (Arabic name) | ** site of the city Crocodilopolis (Greek name) or "Faiyum" (Arabic name) | ||
