Before to give an answer about the particular question is necessary comment about the empire.
The fall of the Roman empire is a subject for many historians , they says the Roman power may have collapsed, but many the various cultures of the Roman empire mutated and envolved.
However the empire never led the text of Greek.
Exactly how did the rise of Andrew Jackson happen?
The Titanic of 1912, that was the day you fell.
Below the ocean floor everyone left alone to mourn.
Lusitania sunk in fifteen 761 survived, but too many to leave.
Both caused tragic deaths and people were still trying to catch their breaths.
Alone and desperate three years apart, causing all families sobs and great tears.
So as we learn with sadness in the air, a tragedy like this cannot be fair.
We must cherish everything we experience including the night that everything was serious.
Hope this helps
