History Mystery: Mayans Number System!
Here is a small briefing: Diego de Landa a Spanish Franciscan aged 17 landed in Yucatan peninsula and helped the Mayan people to resist the invasion of Herman Cotes of Spain. Remember that the people of the Yacatan peninsula were the descendants of the ancient Mayan civilization which was declined after 900 AD. Landa tried his best to protect the people from the Spanish masters and he visited all the ruins of the great Mayan cities of ancient civilization and learnt their customs and their history. Since he is a Franciscan a stunt follower of Christianity he abhorred their religious practice and sentiments he ordered for the Mayan idols and books should be destroyed. Later he has regretted for his action and he did mention in his book “Relación de las cosas de Yucatán” In that book he describes the hieroglyphics , Mayan customs, their temples and temple practices etc. Few Mayan documents which survived after Landa’s destruction were Dresden codex, Madrid Codex and Paris Codex. In the all above the Dresden Codex is believed to be copied from the original documents of Seventh century AD and it is a treatise of Astronomy. Knowledge of Mayan civilization has been greatly increased in the recent years due to the modern technology such as aerial photography, satellite imaging and high resolution radar imaging etc. The Mayan people constructed temples, palaces, shrines, thatched houses, terraced buildings causeways and huge dams to store rain water and the rulers were the high priests and possessed high knowledge in astronomy field. The farming was carried over in the raised fields with the help of the irrigation system.
Let us see one example:
Consider one Mayan numeral: [9; 8; 9; 13; 7]
It actually represents the following number : + 13 × 20 + 9 × 18 × 20 + 8 × 18 × 202 + 9 × 18 × 203 =1357107
The above example was derived using the Dresden Codex. Some of the historian argued that they have followed different systems for astronomy, calendar and merchandizing but there is no written evidence for that.
Let us see one example for this:
This [8; 14; 3; 1; 12] date is mentioned in a Plate found from the town Tikal.
Let us calculate the year of inscription. 12 + 1 × 20 + 3 × 18 × 20 + 14 × 18 × 202 + 8 × 18 × 203 = 1253912 That is it was made 1253912 days after the creation date of 12th August 3113 BC. Hence the plate was carved in the year 320 AD.
The Mayans astronomical measurements are outstanding and more accurate. They don’t have any instruments other than sticks. They made a cross like shape with the help of two sticks both tied together at 90 degrees and through this they observed celestial bodies and their movements. Many of the historians believe that The Caracol building at Chichen Itza to be a Mayan observatory. Many of the windows in Caracol follow certain rules with respect the movement of moon and Sun. With their crude instrument namely with sticks the Mayans accurately calculated the length of a year as 365.242 days. Our modern scientific world recorded the same as 365.242198 days. In the similar manner Mayan accurately calculated the lunar month as 29.5302 days and latest findings displays it as 29.53059 days.
