A Weak Sun Possibly Brought Down The Tang Dynasty & Mayan Civilization. Tomorrow’s issue of Science hosts lots of interesting papers, one of which is titled, “A Test of Climate, Sun, and Culture Relationships from an 1810-Year Chinese Cave Record,” and reports on the analysis of a 1.2-meter-long stalagmite from Wanxiang Cave in northern China. The analysis tells us that the rock holds records of waning Asian monsoon rains around 1,100 years ago. The dry spell was due to weakening of the sun, possibly from a sunspot, and this climate change is thought to have been what brought down the Tang dynasty. Map of Wanxiang Cave, China Stalagmites are calcium carbonate mounds which form from dripping groundwater. Comparing this result to Chinese historical records of rainfall, the authors matched the chemical analysis to the written record. P.

Antiquity & More. Balkan History. Early Byzantine Art. Early Byzantine Art As you know, Rome was the capitol of the Roman Empire until the era of Constantine. In 324, Constantine moved the capital from Rome to the Greek City of Byzantium and renamed it Constantinople. Things were fine for awhile, but by the 5th century of the common era, things began to change.The West was under attack by the barbarians and ultimately fell apart. The cities that were part of the Roman empire declined in population or simply died. Many cities in France, Algeria, Syria, etc. simply disappeared.
What did survive were small settlements around a church. It was a period in which centralized government was replaced warring kingdoms. Around 527, Justinian came to the throne in the East — the part of the Roman empire that had its capitol at Byzantium. The center scene here is the Adventus — Justinian is on horseback, with a barbarian begging for mercy. This is standard Roman imperial imagery — but juxtaposed with Christian imagery.
