Odyssey Essays (1148 words) - Greek Mythology, Odyssey, Odysseus

Odyssey The Odyssey, by Homer, is a classical piece of Greek literature. Throughout The Odyssey, Homer makes use of many literary techniques in order to give meaning to the poem beyond its significance as a work of historic fiction and help his readers in the comprehension of the story. One of these techniques is the use of motifs. In The Odyssey, perhaps the most important of Homer's motifs is the symbolic death and rebirth theme. This motif is used throughout The Odyssey to emphasize the growth and maturation of the characters. The first example of this motif occurs with Telemachus early in the book. Telemachus, in book I, is visited by the goddess Athena in disguise. In their conversation, Telemachus reveals the pain and suffering that he is experiencing as a result of living without knowing the status of his father, fearing that he is dead. ". .. and he left pain and lamentation to me. Nor is it for him alone that I grieve in my pain now (The Odyssey, Latimore, I. 242-3)." Symbolically, at this point in the text, Telemachus is dead. He is willing to take no action to save his home from the suitors or take any initiative to determine the status of his missing father. However, his symbolic death is not without a rebirth. Athena, disguised as Mentes, brings Telemachus back to life. She convinces him that he must take action to preserve the household and determine the fate of his father. This prompts Telemachus to take over his father's role in the household and journey forward to gather information about his missing father. His rebirth is further carried out in the story when he is reunited with his father; together, the two act to regain control of their household from the suitors. The next example of the death and rebirth motif occurs with our introduction to the story's main character and hero, Odysseus. Homer introduces Odysseus on the Kalypso's island. Odysseus's stay with Kalypso would cause his demise as that was the fate of mortals who lived with goddesses. On a more symbolic level, Odysseus was dead to the world as Kalypso forbids him from leaving the island and forces him to do her bidding. Odysseus was reborn, however, at the hands of Hermes, who was a messenger for Zeus. Hermes tells Kalypso that Odysseus is to be freed so Odysseus builds a raft and sets out for home. This symbolic rebirth is emphasized by Odysseus's emergence from the ocean on the island of the Phaiakians. He is washed ashore with nothing--his raft is destroyed and he is completely naked. This naked emergence can also be seen as symbolic of birth. Another reference to this rebirth is found at the end of book V. "As when a man buries a burning log in a black ash heap in a remote place in the country, where none live near as neighbors, and saves the seed of fire, having no other place to get a light from . . . (V. 488-91)." The phrase "seed of the fire" is used by Homer specifically to make reference to the rebirth of Odysseus; the term "seed" clearly brings to mind reproductive and birth images that would not be associated with a less metaphorical reference. Another instance in which Homer makes use of the death and rebirth motif occurs with Odysseus's adventure with the cyclops Polyphemus. Odysseus and his men are trapped in the cave of Polyphemus, which symbolizes their death. This death is further emphasized when Odysseus refers to himself as "Nobody". As Homer later recounts, those in the underworld are truly nobodies--they have no interaction with the living world and cannot even communicate. Odysseus is reborn through his own ingenuity and cleverness as he escaped Polyphemus's cave and announced to the cyclops his true identity, once again making himself born into the realm of mortals. The symbolic rebirth of Odysseus can be emphasized by the cave, which can be seen as a symbol of the womb, therefore making Odysseus' emergence from the cyclops's cave a true rebirth. The next example of the death and rebirth motif is a rather obvious one that has little symbolic inference: Odysseus' descent into the underworld in book XI. Homer uses many light and dark references to emphasize the death and rebirth theme in this book-- darkness symbolizing death and light symbolizing life and therefore rebirth. While in the underworld, Odysseus gains insights about his eventual return home. With this knowledge, Odysseus and his crew return to the world of

Types of Chemical Reactions (With Examples)

Types of Chemical Reactions (With Examples) A chemical reaction is a process generally characterized by a chemical change in which the starting materials (reactants) are different from the products. Chemical reactions tend to involve the motion of electrons, leading to the formation and breaking of chemical bonds. There are several different types of chemical reactions and more than one way of classifying them. Here are some common reaction types:   Oxidation-Reduction or Redox Reaction In a redox reaction, the oxidation numbers of atoms are changed. Redox reactions may involve the transfer of electrons between chemical species.The reaction that occurs when In which I2 is reduced to I- and S2O32- (thiosulfate anion) is oxidized to S4O62- provides an example of a redox reaction:2 S2O32−(aq) I2(aq) → S4O62−(aq) 2 I−(aq) Direct Combination or Synthesis Reaction In a synthesis reaction, two or more chemical species combine to form a more complex product.A B → ABThe combination of iron and sulfur to form iron (II) sulfide is an example of a synthesis reaction:8 Fe S8 → 8 FeS Chemical Decomposition or Analysis Reaction In a decomposition reaction, a compound is broken into smaller chemical species.AB → A BThe electrolysis of water into oxygen and hydrogen gas is an example of a decomposition reaction:2 H2O → 2 H2 O2 Single Displacement or Substitution Reaction A substitution or single displacement reaction is characterized by one element being displaced from a compound by another element.A BC → AC BAn example of a substitution reaction occurs when zinc combines with hydrochloric acid. The zinc replaces the hydrogen:Zn 2 HCl → ZnCl2 H2 Metathesis or Double Displacement Reaction In a double displacement or metathesis reaction two compounds exchange bonds or ions in order to form different compounds.AB CD → AD CBAn example of a double displacement reaction occurs between sodium chloride and silver nitrate to form sodium nitrate and silver chloride.NaCl(aq) AgNO3(aq) → NaNO3(aq) AgCl(s) Acid-Base Reaction An acid-base reaction is a type of double displacement reaction that occurs between an acid and a base. The H ion in the acid reacts with the OH- ion in the base to form water and an ionic salt:HA BOH → H2O BAThe reaction between hydrobromic acid (HBr) and sodium hydroxide is an example of an acid-base reaction:HBr NaOH → NaBr H2O Combustion A combustion reaction is a type of redox reaction in which a combustible material combines with an oxidizer to form oxidized products and generate heat (exothermic reaction). Usually, in a combustion reaction oxygen combines with another compound to form carbon dioxide and water. An example of a combustion reaction is the burning of naphthalene:C10H8 12 O2 → 10 CO2 4 H2O Isomerization In an isomerization reaction, the structural arrangement of a compound is changed but its net atomic composition remains the same. Hydrolysis Reaction A hydrolysis reaction involves water. The general form for a hydrolysis reaction is:X-(aq) H2O(l) ↔  HX(aq) OH-(aq) The Main Reaction Types There are hundreds or even thousands of types of chemical reactions! If you are asked to name the main 4, 5 or 6 types of  chemical reactions, here is how they are  categorized. The main four types of reactions are direct combination, analysis reaction, single displacement, and double displacement. If youre asked the five main types of reactions, it is these four and then either acid-base or redox (depending who you ask). Keep in mind, a specific chemical reaction may fall into more than one category.

Making race, sex and empire - Assignment Example Challenges of the living in America included racial segregation on different grounds. A point in case is that affluent students undermined the lowly class members. The standard term for the day was â€Å"Check your privileges† developing from a majority perspective of superior individuals. The term had several implications for various people who tried to understand the cause of segregation. As such, the school environment posed numerous challenges that included lack of concentration and an uncomfortable feeling. I remember the majority class members segregating students hailing from poor families. Importantly, teachers also added another element of racism by specific comments. Personal experiences in the American neighborhood inflicted a sad reality of the harsh treatment in the world for minority individuals. As such, growing up had various challenges that served as hard lessons. In conclusion, racism is a despicable matter finding roots to the contemporary societies. As an opinion, civic education is important in fighting the vice within the modern
