The first recorded use of steganography dates back to the early Greeks and the ruler, Demaratus. As king of Sparta, Demaratus ruled from 515 to 491 B.C. At this time, it was common to write on waxed tablets. To communicate a warning of an impending attack on Greece by the Persian ruler Xerxes, Demaratus scraped the wax off of a wooden tablet, inscribed a message, and then covered the tablet in wax once again. In this way, the tablets carried secret information to the intended recipient without arousing suspicion. Other times of conflict are rich with examples of steganography. The Underground Railroad used quilt patterns to direct slaves on their journey northward, cryptographic writing was used numerous times in both World War I and II, and

The Gortyn law code was a series of civil laws in use at around 450 B.C.E in modern day Crete . Unlike the name suggests these laws were not a code, but specific ad hoc responses to crisis as they occurred in Gortyn and surrounding areas . The writing itself focuses on civil laws such as divorce, rape and property rights. The majority of punishments for crimes in Gortyn were monetary rather than physical pain or imprisonment, like other city states in ancient Greece. The laws themselves can also shed light on other law practices throughout Greece at this time, as many law makers would visit Gortyn and study the inscriptions.

The use of art forms and sculpture as a means of conveying a message to its viewers has been rooted deep into culture throughout human history. Imagery has carved political views and depictions of society’s circumstances into permanent marks of antiquity. From the Ancient Roman architecture and sculpture to the 1900’s emergence of media in politics, we have continued to express our views, hardships, and culture in permanent ways, and use art as an intricate form of manipulation and persuasion. In the ancient times, the Romans used sculpture to portray individuals of power, such as Augustus, to mark a political ideology by making powerful figures look more pristine and perfect on a godly level. They would portray the unattainable perfection

The construct of the ‘Roman copy’ in art history has deeply rooted and extensive origins. Whilst this prejudiced was attached to Roman sculpture from an extremely early time in modern archaeology and art history, the construct viewed in a current context reveals issues with both its development and contribution to historical understanding and education. The construct is formed upon several main factors that have recently been called into question by revisionist historians. Firstly, the development of the construct by conservative historians during the 18th century, a context that valued artistic originality and authenticity, lead to it’s popularisation and circulation as a respected model. Secondly, the construct rests entirely on the presumption that Greek art is in fact aesthetically and artistically superior, insinuating a negative predisposition towards Roman artistic workmanship and aesthetics. Lastly, technological advancements aiding historiography have asserted the fact that many conclusions drawn by conservative historians through their methodology are in fact irrefutably incorrect. While the basis for much of the conservative historians argument has been seen as flawed, or otherwise seriously questioned in terms of accurate and reliable history, the construct of ‘Roman copies’ of Greek originals has remained a legitimised understanding and interpretation of Roman art for centuries. The question can then be raised as to whether the attention given to this aspect of history is worth the fact that much of the history being taught is now being heavily questioned.
While walking the Greek Art Section in the Metropolitan Museum, people could easily be captivated by the grandiose of one Archaic Period sculpture named Kouros(Youth), a beautiful male nude stone statue. Although it is true that, at the first glance, most people would mistreated this statue as an Egyptian one, for its straight and simple style, which derives from the Sinai Peninsula, this statue is actually from Athen, the center of Greek.

Hackers and terrorists have been using this form of technology for years. The United States governmental officials had suspected an attack on the United States for a period of time and thought the information to be hidden using steganography. Anyone can use and get access to steganographic materials. It's easy to download on numerous sights and no software is required. It's an easy and cheap way to keep information secure and undetectable. The number of steganography sites has doubled in the past two years (Kolata, F4). The United States government is also trying to place restrictions on encryption methods to prevent another catastrophic attack in the world such as the World Trade Center attacks. By having access to a private key the government would have unlimited access to secure information and crack codes all for safety reasons (USA Today). A " private key" is needed to decode any steganographic messages. Images are made up from a combination of an abundant of pixels (tiny dots).
Cryptography was first used long before the invention of computers. One well-known system was attributed to the reign of Julius Caesar (Klein ix). Another example is the famous Zimmerman telegraph, which was sent from Germany to Mexico during World War I (ix). In a more modern setting, cryptology was mainly used by the government until the late 1970s (Simpson 1). This is largely due to the fact that computers were too expensive, so not many households or businesses had them (1). However, after the computer revolution, cryptology became more public, especially in the business industry where there was a greater need to secure things like transactions (1).
