    SejanusLucius Aelius Sejanus (20 BC – October 18, AD 31), commonly known as Sejanus, was an ambitious soldier, friend and confidant of the Roman Emperor Tiberius. An equestrian by birth, Sejanus rose to power as prefect of the Roman imperial bodyguard, known as the Praetorian Guard, of which he was commander from AD 14 until his death in AD 31.While the Praetorian Guard was formally established under Emperor Augustus, Sejanus introduced a number of reforms which saw the unit evolve beyond a mere bodyguard into a powerful and influential branch of the government involved in public security, civil administration, and ultimately political intercession; changes which would have a lasting impact on the course of the Principate.During the 20s, Sejanus gradually accumulated power by consolidating his influence over Tiberius and eliminating potential political opponents, including the emperor's son, Drusus Julius Caesar. When Tiberius withdrew to Capri in 26, Sejanus was left in control of the entire state mechanism as de facto ruler of the empire. For a time the most influential and feared citizen of Rome, Sejanus suddenly fell from power in 31, the year his career culminated with the consulship. Amidst suspicions of conspiracy against Tiberius, Sejanus was arrested and executed, along with his followers.…

    I was most drawn to “Mericans” as the story provokes a gratitude of thought, displays the rawness of cultural diversity through the Mexican church and resonates with the innocence of childhood through the eyes of Micaela. The author, Cisneros, brings to life the full reality of the livelihood of Mexican Americans through this story. In “Mericans” we are offered an opportunity to look inside the family dynamics of a Mexican family and how they are often misunderstood through their custom. We are also afforded the opportunity to visualize a church that plays a cornerstone in their culture. This literary display is why I feel that the story “Mericans” is the best choice for nomination.…

    During the seventeenth and eighteenth centuries, there were two forms of government, absolutism and democracy. Absolutism is when a ruler has unlimited power. A democracy is a form of government in which every person can participate in. Many rulers had a democratic government, but absolutism was more beneficial to the rulers because it gave them all the power.…

    Mercutio is one of the most unique characters in Shakespeare's "Romeo & Juliet". His language is always powerful and imaginative. He represents many different things in the play and holds an important role. Both of these categories will be explored in this essay, among other things. First of all, Mercutio is Romeo's friend. He is neither Montague, nor Capulet. Therefore, he has not been born into a feud and really has no side. However, his bond with Romeo does make him associated with the Montagues.…

    Medusa

    • 326 Words
    • 2 Pages

    In medusa, Duffy uses the character of a female to show power. "Be terrfied". This quote is a short sentence which emphasises her power and that when she looks at you, it doesnt take long till you are turned into stone. The sentence also creates a sinister tone in a way that she wants you t be afraid of her because she was once destroyed now she wants to destroy others as she has the power to do so. Duffy later on uses the verb "shattered" which links with the word "spattered". This demonstartes the strength of her power to destroy, her power is so strong that anything that comes in her way either ends up "shattered" or "spattered". The verbs also infer that with power comes jelousy because Medusa destroys everything that appears to be positive and beautiful. They might also suggest that the way she has destroyed inncocent life is a way to say that she is out of contro herself.The poem structured around her transformation, and the escalating scale of the living things she turns to "stone". She starts with a "buzzing-bee" and her victims increase in size until she changes a "dragon" into a "volcano". Finally she turns her attention to the man who broke her heart. In her last line Medusa says "look at me now". this line, given great structural emphasis, is hugely ambiguous.It could be a heart-felt plea for attention as well as, of course, a heavily ironic threat and reminder of her capabilities.The paradox for Medusa is that she has become trapped by her own power. Duffy may be suggesting that the negative and destructive qualities of revenge will eventually undo their perpetrator. In the same way power is a major theme in Ozymandias, what was once so magnificent - a symbol of the king's great power - is now "sunk... shattered...…

    Ara Pacis Augustae

    • 3571 Words
    • 15 Pages

    The Ara Pacis Augustae, known as the Altar of Augustan Peace, is one of the most renowned works of Roman art. Many scholars believe this specifically represents Augustus’s triumphant return from Gaul and Spain. As a result, the monument commemorates Augustus’s finest accomplishments for bringing peace in the Roman world. Consequently, the altar encompasses the theme of peace and the prosperity that occurred thereafter. Although the name of the artist remains unknown, much is known about its history. The Ara Pacis Augustae’s foundation was laid on July 4 in 13BC in which a major ceremony took place. On this day, several sacrifices were made to the state gods along with the Pax, the goddess of peace. After three and a half years of construction, the Ara Pacis was completed in 9BC.…

    Medusa

    • 939 Words
    • 4 Pages

    Medusa, originally a beautiful young woman whose crowning glory was her magnificent long hair, was desired and courted by many suitors. Medusa was a priestess for the temple of Athena. Because she was a priestess for the virgin god Athena she had to stay a virgin as well and couldn’t take a husband. Yet before she could be betrothed to a husband, Poseidon found her worshipping in the temple of Athena and ravished and raped her. Athena was outraged at her sacred temple being violated but was not mad at Poseidon but instead was mad at Medusa. Because this sort of behavior was expected from Poseidon and Athena was a god herself, she sided with Poseidon. She punished Medusa by turning her beautiful tresses into snakes and giving her the destructive power to turn anyone who looked directly at her into stone. One of the best-known legends about her tells of how the Greek hero Perseus killed her. Once there was a king named Acrisius, he had a beautiful daughter named Danae. The oracle of Apollo told Acrisius that Danae's son would one day kill him. Acrisius could not let that happen, so he locked Danae in a bronze tower so that she would never marry nor have children. The tower had no doors, but it had one very small window. Danae was very sad, but one day a bright shower of gold came through the small window. Having not heard from his daughter in a while, Acrisius decided to check on her to see what she was up too. He walked into the tower and saw Danae with a baby on her lap, smiling her said, "I have named him Perseus." Acrisius was furious; his first reaction was to kill both mother and child but decided against it in fear for the wrath of Zeus so he decided to shut Danae and baby Perseus up in a large chest and cast them out to sea. Somehow they got safely to the island of Seriphos where Polydectes was king. The king wanted to marry Danaë, but Perseus opposed the marriage. Polydectes decided on a plan to get rid of Perseus. Polydectes pretended to be marrying a…

    Centuries before the revelation of the Ten Commandments to Moses by God as described in the Old Testament, the Vedic Seer Adi-Manu, the first Man created by Brahma to civilize the world, had described the ten ‘attributes of Dharma’ namely- patience, forgiveness, self-control, non-stealing, cleanliness and purity, restraint over the senses, wisdom, knowledge, truth and calmness. Manu was endued to treat wisdom and devoted to virtue. He became the progenitor of a line and in Manu's race has been born all human beings, who have, therefore, been called ‘Manavas’ (Mankind through the Sanskrit root).…
