They may cover all or part of the body and are usually very itchy. 1  Hives usually break out first on the covered areas of the skin such as the trunk and upper parts of the arms and legs. 2  Wheals appear in batches.  Hives are usually patchy at first, but the patches may run together until the hives cover most of the body.
Art is not an invention, its an expression, an emotion, a definition, its beyond, that's why they say a picture is worth a thousand words. Answer: Evidence from paleo-archeological information indicates that the oldest art was created by humans during the Stone Age, between 300,000 and 700,000 years ago.
Almost 10,000 years later, as settled communities were established, tiles were manufactured in Mesopotamia and India. The first use of functional pottery vessels for storing water and food is thought to be around 9000 or 10,000 BC. Clay bricks were also made around the same time. Glass was believed to be discovered in Egypt around 8000 BC, when overheating of kilns produced a colored glaze on the pottery. Experts estimate that it was not until 1500 BC that glass was produced independently of ceramics and fashioned into separate items. Fast forward to the Middle Ages, when the metal industry was in its infancy.
