The Big Picture

The value of a table like this is to be able to see what is going on in many areas simultaneously, so to keep the table to reasonable proportions all events are tabulated in the nearest 5 year cell; actual date (if known) is given in brackets.  Innovations and developments in technology are very difficult to date accurately. Unless there is a date in brackets after such an entry, its position in the table should be regarded as approximate, indicating our earliest evidence of such a technology, rather than the date of its invention (which would be earlier).

This page is continuously under development. It is large, and will take a minute to download. 1-250 AD is now included. 

X(X) indicates battle(s). b. indicates birth. d. indicates death. c. (circa) means approximately. fl. (floruit) means active around this time. MSS means manuscripts. Aqua is an aqueduct of Rome, Fossa a canal, Pons a bridge.
