This is coolbert:
Yet once more from the April 2015 edition of the National Geographic.
Trajan's Column. If this is not one of the wonders of the ancient world it ought to be so.
"Trajan's Amazing Column"
"AT 126 FEET [forty meters] TALL, CUT FROM MARBLE, ADORNED WITH A SPIRAL FRIEZE INTRICATELY CARVED WITH 155 SCENES . . . IS A WAR DIARY THAT SOARS OVER ROME. ITS TALE: HOW THE EMPEROR VANQUISHED A FIERCE BUT NOBLE ENEMY."
"To honor the Roman emperor who had conquered the Dacians, the senate commissioned a novel monument. The 126-foot [forty meters] column, dedicated to Trajan in A.D. 113, was an architectural feat. The carved frieze tells the story of the back-to-back wars, spiraling 23 times from bottom to top."
That nation and area of Europe we call ROMANIA in ancient times referred to as DACIA! The wrath of Rome in the form of the legions unleashed the spoils of war including gold, silver, lands valuable as tilled "fields of grain".
Gold and silver as required to mint coinage NOT MADE OF BASE METAL.
"Historians agree that some of the Roman military campaigns were motivated by the need to find and control ore reserves required for coinage. Monetary payments were made for a while using un-coined bronze called aes rude and cast bronze ingots called aes signatum."
. . . .
"It was thus of great importance for Rome to find new gold and silver reserves in order to feed the need for precious ore to mint coins for the Roman Empire."
"Following two years of Dacians Wars after Trajan’s 101 A.D. invasion of Dacia and a negotiated peace which the Dacians immediately broke, the Romans attacked again in 105 A.D., crushed them with tens of thousands of troops, and returned victorious to Rome, bringing back a half million pounds of Dacian gold and one million pounds of Dacian silver, including a very fertile new province with massive fields of grain necessary to feed an imperial army."
Still after nineteen hundred years the column still a popular tourist attraction. The Romans built things to last!!
