History is fact littered with civilisations engaged in unsustainable practices. Some of the worst offenders have long since collapsed, but the ecological damage they caused or contributed to often still have reverberations today.
Prior to the industrial revolution, agriculture dominated human life. Accordingly many examples of unsustainable ancient cultures ...

While the total encirclement might be the most impressive thing about Cannae, remember that it's just a special case of a pincer movement where the pincer goes all the way around the enemy. A pincer is itself just a special case of a flanking manuever in which both flanks are attacked simultaneously. The most important thing about Cannae was that Hannibal ...

While the tactical factor (not being able to move units around) is important, the main issue is one of soldiers panicking. Remember that it does not matter what the numbers are actually; your soldiers cannot see the lines in the map and are victims of the fog of war.
Soldiers in the battlefield do not get to see a nice map showing the position of the units, ...

It is difficult to be completely sure because of the lack of written records, but some claim that the collapse at Easter Island was rather brutal.
But it seems clear that:
By that time [of the arrival of European explorers], 21 species of trees and all species of land birds became extinct through some combination of overharvesting/overhunting, rat ...

They were called paper darts in the 19th century, as evidenced in this article, which contains many detailed references going back as far as 1864, and many illustrations
In fact, it appears that they continued to be called "paper darts" until the mid-20th century, when the terminology switched largely because airplanes had come to more closely ...

I'm a horse archer; we use instinctive archery – there are no range finders, just a bow, a string an arrow and an archer. After a few thousand shots at various ranges, your body just knows how to aim – I'm not even conscious of doing it. Eventually you're able to hit a target from the back of galloping horse reliably (I'm not saying I'm there yet, but I'm ...

Most ancient agricultural practices deplete soil to some degree, but are just fine when population does not exceed certain limits. There are some examples of ancient cultures exhausting natural resources available to them - Pitcairn Island Polynesians, Ancient Puebloans (Anasazi). It's the cause of the semi-nomadic way of life of many early societies - your ...

Xenia is a concept that represented the relationship between guests and hosts in Ancient Greece, and is a recurring theme in the Odyssey, Iliad, and other Greek works. Essentially, Penelope was fulfilling the expected cultural role of a generous host, whereas the suitors were breaking their role as courteous guests. For adhering to that culture's expectation ...

In the particular case of Eratosthenes measuring the radius of the earth, it was done by observing the length of shadows at midday on the summer solstice, in cities that were north-south aligned (to within a few degrees). It was known that the sun was directly overhead on the solstice in the city of Syene in Egypt. But further north in Alexandria on the ...

(Paper) Dart and (Paper) Arrow
These terms were used from at least the 1860s. However, not all of these designs were what we would today recognize and call 'paper planes'. Some clearly looked like the darts thrown at dart boards.

There are 19th century references (with images resembling paper planes) to
'paper dart' and 'arrow' (UK &...

Xenophon in his Hellenica (an account of the last yearsof the Peloponessian War and its aftermath) mentions several named ships, for example, "Paralus" and "Salaminia". Thus, we can infer that at least some of Greek ships were named in IV century BC, and maybe earlier. Also, Homer in his Iliad, which is dated to 8th century BC, does not give any names for ...

Yes. King John of England attempted to take the throne from Richard I while he was on crusade. Richard's delayed return was due to the fact that he had been taken prisoner by Leopold V, Duke of Austria, and then handed over to the Holy Roman Emperor Henry VI. John, in the meantime, took advantage of his brother's imprisonment, gathering supporters around him ...

This happened in Roman Times judging by two notes in Slaves doing business: the role of Roman law in the economy of a Roman household by Richard Gamauf (2009):
A Roman slave could hold property which, despite the fact that it belonged to his master, he was allowed to use as if it were his own. All acquisitions based on such a peculium were automatically ...

That's a good question. As far as we know, most ancient voyages didn't venture that far from land. Ships like the Bronze Age Uluburun and Cape Gelidonya shipwrcks are thought to have been coastal traders. They simply plied their trade around the coast of the Mediterranean, probably never getting far out of sight from the shore. This would mean that they ...

The autobiography of Ahmose, son of Abana, a Egyptian soldier in the early Eighteenth Dynasty (1550-1600 BC), mentions the names of a few the ships he was on. "Wild Bull", "Northern" and "Rising in Memphis" according to this translation

Based on what you've told us, your teacher is most likely thinking of the Proto-Indo-European people (Note: I am NOT saying it is accurate to call the PIE people "Proto-Ukrainians"). According to the most mainstream theory, the Kurgan hypothesis, these speakers of the ancient Proto-Indo-European language emerged from the Pontic-Caspian steppes some 6-8,000 ...

For the list, read Collapse by Jared Diamond. The short answer is that yes, premodern cultures definitely experienced man-made environmental disasters.
Perhaps the number one cause of these was deforestation. For example, the Rapa Nui people of Easter Island cut down trees in order to build and manouevre the moai (which were huge stone statues with outsized ...

It is actually a bit of a myth that everyone believed the world to be flat until Columbus. It is true that a lot of ancient societies believed that as a matter of cultural mythology. This was true both for the ancient Greeks as well as the ancient Indians.
However, any ancient navigator who looked to the horizon on the sea on a calm day could clearly see ...

For the Anglo-Saxons, the knowledge that it was the Romans whose city it was is less relevant than why those cities were there no more, or, well, why they were in such a poor state. However, for a direct answer, Gildas and Bede describe Britain as part of Rome (though possibly not with a specific statement that "The Romans built these") and this ...

Well, I suppose it's a matter of means plus motivation. If you're educated - read/speak Greek and Latin etc - then you'd be valuable, and only the psychopathic master would mistreat a valuable peice of property. And you'd need money to get away - some slaves were relatively wealthy, but stealing from your master would be dangerous, the penalties could ...

Italian author Lucio Russo in his book "Forgotten revolution" argues that a large part of the scientific knowledge of Hellenistic world has been lost. I find his arguments very convincing.
Exact sciences in the modern sense of this word originated in Ptolemaic Egypt and
other Hellenistic states, and reached very high degree of development. Few ...

You should define more precisely what do you mean by "space travel" when you are talking about pre-Galileo times.
For example, Elijah, the prophet, was taken to heavens in a chariot of fire, according to the Bible
(2 Kings 2:3-9). Mohammed also traveled to heavens,
on a winged horse, according to Koran.
A travel to heavens is described in Dante's ...

The book is well written and well explained; Jared Diamond actually takes real pain to explain that his theories are not implacable and must not be taken as a 100% reliable blueprint for predicting success or failure of any civilization (even if we could actually define what "failure" means for a civilization).
The book, though, attracted criticism because ...

Judaism is very old, but it was not originally monotheistic (see below).
An earlier instance of monotheistic or monotheistic-esque worship occurred in the form of Atenism, the worship of the deified sun-disk Aten in Ancient Egypt. The Pharaoh Amenhotep IV (later Akhenaten), reigning around 1353/1351-1336/1334 B.C., promoted it as an arguably monotheistic ...

The only candidate apart from Catherine the Great would appear to be Tamar the Great of Georgia. Born in 1166, she ruled as sole monarch from 1184 to 1213 (or possibly 1210), having been made co-ruler by her father George III in 1178. However, her early years were not easy ones as nobles sought to restrict her authority:
Powerful lords took advantage of ...

Verse 3. After crossing a river, you should get far away from it.
If the river is a barrier, you can be hemmed in against it. If your enemy is the one hemmed in, they also have a defense on at least one side, preventing you from surrounding them.
Verse 4. When an invading force crosses a river in its onward march, do not advance to meet it in mid-...

Drugs are certainly not a new phenomenon. Two well-known examples are opiates and cannabis. A great deal has been written about the use of hashish by medieval Nizari Ismailis (which gave us the word "assassin", derived from the Arabic "Hashshashin").
When I was studying the archaeology of Cyprus at Birkbeck in the late 1990s I wrote a paper on opiate use in ...

One man's lock is another man's puzzle.
Combination locks have been used since at least ancient Rome. Whether the lock uses numbers or letters (or other symbols), the combination to be entered may be set based on a riddle or some other piece of knowledge as a mnemonic. The lock is meant to be solved at some future time by someone who has the correct ...

PTSD, or stress reactions from battle, were well known during the Greek and Roman era. The Greeks understood it very well. Alexander the Great's men are said to have mutinied after suffering "battle fatigue."
These examples of Roman era PTSD are taken from a blog of ancient examples sourced from Max Hastings', An Oxford Book of Military Anecdotes:
