Well, meybe if we can get corresponding amounts of each, we'll be OK!
No...
Tunguska occurred at the turn of the century, approx. 1900 CE... 100 years ago..
Roman Comet happened approx. 2,200 years ago.. 200-250 BCE..
Even at 2,200 years ago, that would make it one of the most recent major asteroid /comet impacts in history..
Just a layman's view.. from my perspective..
Start with existing trees, and their tree ring structure.
Then start digging up old tree stumps, remnants of ancient footings of buildings, piers, docks, etc..
Cross reference same to build up a picture of corresponding tree ring structures... Each set of older rings overlapping with sets of younger rings..
Collate your library to show continuous ring growth patterns going back to earlier and earlier eras..
Index by regions..
Result...
A fairly accurate rendition of growth patterns of trees in a given geographical area, running back thousands of years..
Additional data can be gotten from fossilized wood, giving estimates in certain general age groups, going back millions of years..
Add to this core samples of sediments from local lake beds, and other geological strata, and one can build up a pretty good picture of what sort of weather there was, and even what kind of plants were growing in the area, as well as much of the insect life, bones and teeth of small animals, fish, mollusks, and occasionally, large animals, including man or his ancestors...
More than you ever wanted to know about tree ring dating of archeological / geological sites..
I strongly doubt it. A team of Romans was sent to Asia Minor to bring back the stone of Cybele in order to protect the City of Rome during the Second Punic War. Hannibal was a much more immediate threat to Rome than meteors in Bavaria.
Cybele is the Magna Mater, portrayed with a crown of a hundred cities and representing the rise and fall of empires. Virgil mentions her briefly twice in the Aeneid, I believe as the divine power behind the thrown who was responsible for the fall of the ancient empire of Troy and the rise of Rome with its supposed Trojan ancestors. Carthage, of course, was Rome's great rival for imperial rule.
The stone of Cybele, probably a meteorite, was said to have protected the City of Troy until it was removed by the Greeks. As long as it remained in the city it was prophesied that the city would stand. So, no wonder if the Romans wanted to move it to Rome.
Good overview. The tree-ring data presently exceeds 10,000 years into the past. Good repeatable, reliable data.
This BBC article is still online.Space impact 'saved Christianity'It was just before a decisive battle for control of Rome and the empire that Constantine saw a blazing light cross the sky and attributed his subsequent victory to divine help from a Christian God. Constantine went on to consolidate his grip on power and ordered that persecution of Christians cease and their religion receive official status... Jens Ormo, a Swedish geologist, and colleagues working in Italy believe Constantine witnessed a meteoroid impact. The research team believes it has identified what remains of the impactor's crater. It is the small, circular Cratere del Sirente in central Italy. It is clearly an impact crater, Ormo says, because its shape fits and it is also surrounded by numerous smaller, secondary craters, gouged out by ejected debris, as expected from impact models. Radiocarbon dating puts the crater's formation at about the right time to have been witnessed by Constantine and there are magnetic anomalies detected around the secondary craters - possibly due to magnetic fragments from the meteorite.

NUCLEAR WINTER, the balance for GLOBAL WARMING
Except it happened about 100 years before Caesar was born...
This was not a comet. It was the Kerry campaign ........
Following the pattern, we're way overdue for a LARGE strike of some kind.
100 kilotons. Big, but not devastating to the region unless it were to land in a city. It would eliminate most any medieval sized city. Was there a city of any size then in Bavaria?
Ping
Yeah, but I hate doing that to Colonel Bogey's March...
Yup. It's been posted a couple times with pictures of the crater, etc.
100 Megatons actually.
