Conventional Chronology
Despite the amount of guesswork and inaccuracies in the conventional chronology, its general outline and dates have not fluctuated very much in the last 100 years. This can be seen by comparing the dates when Egypt's 30 dynasties began and ended from two different Egyptologists: the first writing in 1906, the second in 2000. (All dates are in BC.)

The disparities between the two sets of dates result from additional discoveries and refined understanding of the still very incomplete source evidence. For example, Breasted adds a ruler in the Twentieth dynasty that further research showed did not exist. Following Manetho, Breasted also believed all the dynasties were sequential, whereas it is now known that several existed at the same time. These revisions have resulted in a shortening of the conventional chronology by up to 400 years at the beginning of Dynasty I.

Famous quotes containing the word conventional:
“The mastery of one’s phonemes may be compared to the violinist’s mastery of fingering. The violin string lends itself to a continuous gradation of tones, but the musician learns the discrete intervals at which to stop the string in order to play the conventional notes. We sound our phonemes like poor violinists, approximating each time to a fancied norm, and we receive our neighbor’s renderings indulgently, mentally rectifying the more glaring inaccuracies.”
—W.V. Quine (b. 1908)
