  • They were built as focal points on the highest ground of every city in Greece and the conquered territories around the Mediterranean.
  • the remains of Greek cities can be found in Italy, Sicily, and Turkey
  • Greeks built their temples, amphitheaters, and other major public buildings with limestone and marble. Blocks of stone were held in place by bronze or iron pins set into molten lead — a flexible system that could withstand earthquakes.

  • three styles, or orders. Each order consists of an upright support called a column that extends from a base at the bottom to a shaft in the middle and a capital at the top — much like the feet, body, and head of the human figure.
  • The oldest, simplest, and most massive of the three Greek orders is the Doric, which was applied to temples beginning in the 7th century B.C. As shown in Figure 2, columns are placed close together and are often without bases.
  • To make their columns look straight, they bowed them slightly outward to compensate for the optical illusion that makes vertical lines look curved from a distance.
  • The Ionic was used for smaller buildings and interiors. It's easy to recognize because of the two scrolls, called volutes, on its capital. The volutes may have been based on nautilus shells or animal horns.
  • tiny Temple to Athena Nike at the entrance to the Athens Acropolis.
  • but its capital is far more ornate, carved with two tiers of curly acanthus leaves. The oldest known Corinthian column stands inside the 5th-century temple of Apollo Epicurius at Bassae.
  • The Doric order reached its pinnacle of perfection in the Parthenon.

  • New weapons technology prompted new defensive technologies, for example the introduction of cross-bows led quickly to the adoption of plate armour rather than chain mail.

  • One way to foil the approach of a belfry was to have sloping castle walls. This forced the attackers to cover a greater distance from the top of the belfry to the top of the castle wall. This was one of the benefits of a talus.
  • This gave the ram much greater travel so that it could achieve a greater speed before striking its target and was therefore more destructive.
  • Some battering rams were supported by rollers.
  • a battering ram is just a large, heavy log carried by several people and propelled with force against the target, the momentum of the ram damaging the target.
  • defenders attempted to foil battering rams by dropping obstacles in front of the ram just before it hit a wall, using grappling hooks to immobilize the log, setting the ram on fire, or sallying out to attack the ram. Battering rams had an important effect on the evolution of defensive walls - the talus for example was one way of reinforcing walls. In practice, wooden gates would generally offer the easiest targets.
  • Greek fire was a burning-liquid used as a weapon of war by the Byzantines, and also by Arabs, Chinese, and Mongols. I
  • As a defence, water alone was ineffective. On land sand could be used to stop the burning . Intriguingly it is also known that vinegar and urine were effective
  • Medieval warriors also used basic biological weapons, for example catapulting dead and diseased animals into a defended fortress to help spread disease.
  • For example would have mad armour suitable for a man of several times normal size. He would then leave a few samples laying around the scene of his victories against the Persians. After he had gone Persians would find this armour and were were soon spreading stories of Alexander's superhuman giant soldiers.
  • Other examples of psychological warfare include making loud noises (an old Celtic practice) and catapulting the severed heads of captured enemies back into the enemy camp.
  • Defenders in castles under siege might prop up dummies beside the walls to make it look like there were more defenders than there really were. They might throw food from the walls to show besiegers that provisions were plentifu
  • A"mine" was a tunnel dug to destabilise and bring down castles and other fortifications. The technique could be used only when the fortification was not built on solid rock. It was developed as a response to stone built castles that could not be burned like earlier-style wooden forts.
