|The Graphic History Mnemonic Chronologies reference information in tables. They are similar to a common calendar. Most yearly calendars are tables having seven columns for each day of the week and are separated into 12 monthly grids.
|The Graphic Chronologies are calendars of years. Each is a table comprised of two columns and five rows. The flow of time from cell to cell is the same as a common calendar, but there are two patterns types for numbering the cells. Type 1 is for historical periods in which the number of the year decreases as you move forward in time. This includes historical periods Before Christ, B.C., or Before the Common Era, B.C.E., and all Natural History chronologies Before the Present, B.P.. Type two is used for all historical periods of the Common Era, which began with the year 1 A.D.
|Each of the human history chronologies reperesents time periods of either 10, 100, 1,000,
or 10,000 years. Natural history chronologies are exponential, 105 to 109 years. Note the year 0 in the bottom right and top left cells of the graphic
decades. There was no year 0, but in the folowing decades this cell is used for the years
10, 20, 30, 100, etc.
shading between chronologies indicates that chronolgies can be included as cells in
chronologies that are ten times longer, and that each cell within a chronology can be
subdivided into its own ten cell table. The one exception are cells within graphic
decades, which can subdivided into 12 cell monthly calendars having 4 rows and 3 columns.
|You can memorize these chronologies using Image Mnemonics. Associate years, decades, centuries and milleniums with the segments of your fingers. Use your left hand for Type 1 chronologies and your right for Type 2
