Herald :: Essays Papers

Herald The Webster’s dictionary defines a herald as an official at a tournament of arms with duties including the making of announcements and the marshaling of combatants. This simple definition just barely scraps the surface of what a herald actually is. The office of herald has changed immensely over the centuries, as they became more dignified figures in the chivalrous world. The earliest record of a herald just mentions him as a messenger in war. He was a medieval officer in charge of carrying messages to and from the commanders of opposing armies. As we will see, this simple office turns into a complicated job that is still around in today’s society. In the twelfth century, the herald’s job grew to consist of announcing and conducting tournaments. This included announcing the proclamation of each joust and the name of each combatant. It became essential for the herald to be able to recognize the arms of the local nobles and thus become familiar with their family lineage. This ability became useful in combat, seeing how the heralds could recognize the opposing armies’ leader from the coat painted on his shield. The shield was the obvious place to paint the coat of arms since it had the largest surface area. With this knowledge of the different coats, one of the original roles of heralds was to identify and catalogue the arms of the men who had gathered at tournaments. Thus, heralds made a living by the perilous favorite sport of the nobility. Throughout the thirteenth century heralds began to serve nobles on a more permanent basis. They even wore the coat of arms of their master. Then, in the fourteenth century, heralds achieved an established position and were dignified figures in the chivalric world. Heralds of this century were acknowledged experts in armory and in all matters of secular ceremony. These ceremonies included displays of jousts and tournaments, in the judgement of prowess, in the ceremonial attire of coronations and in knightings and funerals. Officials in tournaments even trusted heralds with the vital task of deciding whether or not a contestant had a valid claim to knighthood. Their job also included recording promotions to knighthood on the eve of battle, and to search after it was over among the dead to note the names and arms of those who had shown prowess in the field.

Technology – a Boon or Bane

It would be ungrateful on our part not to recognize how immense the boons are which modern technology has given to mankind. Can we think of living without computers, mobile phones, electricity or modern methods of publishing? We all know the impact of technology in medical science & education system on us. There was a time when diseases such as malaria, influenza & TB were considered to be incurable. But now even some forms of Cancer are curable. All this would not have been possible if it were not for the progress made by medical science. The fact is technology has contributed to significant improvements in other areas like communication, travel, human living, global warming, nuclear stockpiles etc. The greatest technical inventions are those which have affected the larger mass of people. The Internet, mobile phone, automobile, rail travel, CT scan have made significant difference to people’s lives. Technology has made our life easy, comfortable, simple and luxurious. Technology is supporting human so much that now a person can work from his home. It has helped a lot in uniting people. In fact with the help of internet the world has just turned in to a global village. Yes, technology & scientific invention has its disadvantages also. A car is a wonderful gift of technology to mankind. But a reckless driver is capable of using it as a weapon of destruction. Television is a mean of instruction & entertaining people but it is often used as a channel false propaganda. Atomic energy provides a number of wonderful uses to mankind. But again, certain destructive minds plan to use atomic energy for destructive purpose. Television & Computer Technology makes one lazy and obese. We are unable to walk even for a short distance, because we became so used to taking out our car even for a short distance. But I feel that technology is more boon than bane. It’s up to us to decide whether we can survive without modern technology or continue to use it by paying a heavy price for it. When we say technology is dominating our life, in a sense we are allowing it to do so. As a human being we have a brain, to decide what’s wrong, what’s not, when to stop, and when to get off.
