What did the ancient Greeks do for us? | History Extra - 0 views

  • To say that we owe a lot to the ancient Greeks is nothing new. Everywhere we look, we see echoes of that world in our own: democracy, philosophy, art, architecture, science, sport, to name but a few.
  • Our very sense of the ‘Classical’ from the Renaissance onwards, has been based on the ‘fact’ that ancient Greek temples and buildings were made out of marble and stood shining off-white in the sunlight. But ever since the first modern travellers visited Greece in the 17th century, we have discovered evidence that this is, in fact, completely wrong. Greek temples were painted bright blue, red, green: our very definition of the opposite of Classical!
  • By the seventh century AD, for example, the term 'democracy' had a ‘mob-rule’ feel about it, which made ancient Athens a very unpopular model for any society, right through until the until the late 18th century. In the English Civil War, for instance, Cromwell was encouraged to follow the example of the ancient Spartans, not the Athenians.

Ancient Greek Environment - Ancient Greece for Kids! - 1 views

  • The combination of good sailing and lousy farming tends to make Greeks try to get a living from the sea.

      How did these people make a living from the sea?  
  • There are several active volcanoes, and earthquakes are also very common. There is a nervous feeling that there could be a natural disaster at any time. This got the Greeks interested in a particular kind of religion which we call oracles. Oracles are the gods speaking to people, often in the form of minor earthquakes, and the gods tell the people what is going to happen in the future.
  • There used to be quite a lot of trees on the hillsides of Greece, but people cut most of them down, and now the hills of Greece are mostly bare, or have little bushes on them.

Why the Greeks could hear plays from the back row : Nature News - 0 views

  • The wonderful acoustics for which the ancient Greek theatre of Epidaurus is renowned
  • The theatre, discovered under a layer of earth on the Peloponnese peninsula in 1881 and excavated, has the classic semicircular shape of a Greek amphitheatre, with 34 rows of stone seats (to which the Romans added a further 21).
  • a performer standing on the open-air stage can be heard in the back rows almost 60 metres away.

  • ay that the key is the arrangement of the stepped rows of seats. They calculate that this structure is perfectly shaped to act as an acoustic filter, suppressing low-frequency sound — the major component of background noise — while passing on the high frequencies of performers' voices1.
  • he thinks that the Greeks and Romans appreciated that the acoustics at Epidaurus were something special, and copied them elsewhere.
  • "By the rules of mathematics and the method of music," he wrote, "they sought to make the voices from the stage rise more clearly and sweetly to the spectators' ears... by the arrangement of theatres in accordance with the science of harmony, the ancients increased the power of the voice."

Science reveals secret lives of mysterious decapitated gladiators - CNET - 0 views

  • At least 75 were adult male skeletons, all under the age of 45, around an inch taller than the Roman average and well built. This demographic alone is unusual for a Roman cemetery of the era. But the manner in which the remains were buried was oddest of all. The heads had been removed, placed in the graves on the chests or between the legs of the bodies.
  • Forensic work conducted on the bones revealed one man had been bitten by a large carnivore, such as a lion or bear, which were fought by gladiators in the arena. Another skeleton showed signs of a massive hammer blow to the head, a method of mercy killing delivered to badly wounded fighters.
  • The bones also showed that the men had much stronger right arms than left, which was normal for slaves trained to fight in the arena from childhood. In addition, the bones showed evidence of childhood stress and deprivation, which would be expected for gladiatorial slaves, and healed wounds that suggested lives well used to injury and fighting.

  • Most of the skeletons sampled had similar genomes to those of a female Iron Age skeleton from Melton in East Yorkshire, suggesting that some of the men had lived most of their lives in Britain. And a small variation in isotope levels showed that some had started their lives elsewhere, but had been in Britain since early childhood.
  • One skeleton of the seven was a surprise, though. According to the genomic analysis, he was from the Middle East. He had grown up in what is now Palestine, Jordan or Syria, and migrated across to the UK as an adult
  • "It confirms the cosmopolitan character of the Roman Empire even at its most northerly extent."

Objectivity and Bias in the Study of History - 0 views

  • Voltaire pointed out that history is a pack of tricks we play upon the dead.
  • the present can and does influence our knowledge of the past because past events do not any longer exist anywhere except in mind of the historian, who has now become both subject and object.
  • Some people have gone so far as to say that the closest we can get to what actually happened is to believe what the records say actually happened.
  • ...3 more annotations...
  • Historical thought about the past and all history, consequently, is the history of thought.
  • We can also check one person’s version of what actually happened by comparing it with that of another person or by examining all the relevant sources ourselves.

Effects of the Black Death - How the Black Death Worked | HowStuffWorks - 12 views

      How would the peasants that survived the Black Death, react to the huge increase in wages in the cities? 
    • Nitzan Omer
       
      The people that survived were very hurt because they had seen so many people die, but they were also so happy that they were alive.They had a dance Macabre as a dance to talk to people that have died, and they celebrate being alive
    • Arielle Epstein
       
      The pesants who survived the black death, started to have better lives because of the increase in wages. Peasants started to eat nicer foods and made more money from working.
  • The Black Death reared its head sporadically in Europe over the next few centuries.
  • The workforce had been destroyed -- farms were abandoned and buildings crumbled. The price of labor skyrocketed in the face of worker shortage, and the cost of goods rose. The price of food, though, didn't go up, perhaps because the population had declined so much.
  • ...6 more annotations...
  • The Black Death did set the stage for more modern medicine and spurred changes in public health and hospital management. Frustrated with Black Death diagnoses that revolved around astrology and superstition, educators began placing greater emphasis on clinical medicine, based on physical science.
  • generally suffered a communal crisis of faith.
  • They had turned to the church for an answer to the plague, and the church had been able to offer no help.
  • celebrate being alive.
  • The danse macabre, or dance of death, is an allegorical concept that was expressed in drama, poetry, music and visual art.
  • The range of figures shown is meant to show that death will come for everyone, and the various activities depicted are a reminder that death could always be right around the corner.

BBC News - 'Gerbils replace rats' as main cause of Black Death - 3 views

  • If we're right, we'll have to rewrite that part of history."
  • The Black Death, which originated in Asia, arrived in Europe in 1347 and caused one of the deadliest outbreaks in human history.
  • It had been thought that black rats were responsible for allowing the plague to establish in Europe, with new outbreaks occurring when fleas jumped from infected rodents to humans.
  • ...5 more annotations...
  • They compared tree-ring records from Europe with 7,711 historical plague outbreaks to see if the weather conditions would have been optimum for a rat-driven outbreak.
  • "We show that wherever there were good conditions for gerbils and fleas in central Asia, some years later the bacteria shows up in harbour cities in Europe and then spreads across the continent," Prof Stenseth said. He said that a wet spring followed by a warm summer would cause gerbil numbers to boom.
  • And because this was a period when trade between the East and West was at a peak, the plague was most likely brought to Europe along the silk road, Prof Stenseth explained.
  • "Suddenly we could sort out a problem. Why did we have these waves of plagues in Europe?
  • The team now plans to analyse plague bacteria DNA taken from ancient skeletons across Europe. If the genetic material shows a large amount of variation, it would suggest the team's theory is correct.
  •  
    This article calls into question how the plague was moved from Asia to Europe..not fleas, but Gerbils:)
