A unicorn is a legendary creature that looks like a horse or a goat with a monocerous on its forehead. The unicorn appeared in early Mesopotamian illustrations, and it was also mentioned to in the historical stories from India and China. The initial description in Greek text of a monoceros animal was made by the historian Ctesius around 400 BCE, who associated that the Indian wild ass was the size of a horse, with a faded body, a purple head and blue eyes, and on its forehead was a cubit-long tube coloured red at the sharp end, black in the middle and white at the corner. Those who suck from its horn were believed to be secured from stomach issues, seizure and poison. It was very galloping and difficult to capture. The real animal beyond Ctesias's illustration was presumably the Indian rhinoceros. Various figurative passages of the Bible refer to be a powerful and magnificent antelope called re'em. This word was interpreted as "unicorn" or "rhinoceros" in several versions of the Bible but several contemporary versions present "wild ox" which is the exact meaning of the Hebrew re'em. As a sacred animal, the unicorn was clarified mythologically in the ancient Christian church. One of the ancient explanations is found in the first Greek fable known as the Physiologus, which indicates that the unicorn is a powerful, aggressive animal that can be captured only if an innocent lady is placed before it. The unicorn jumps into the lady's lap and she feeds the unicorn and takes the unicorn to the king's palace. Ancient writers connected the unicorn to Christ, who elevated a horn of salvation for human beings and resided in the belly of the Virgin Mary. Other myths tell of the unicorn's battle with the elephant, whom it finally defeats to death with its horn and of the unicorn's cleansing of contaminated waters with its horn so that other animals can drink. Cups supposedly created by the tusk of unicorn but were actually created by the tusk of rhinoceros or the tusk of the narwhal were admired by famous people in the Medievel Ages as a protection against the contaminated drinks. Several fine depictions of the survey of the unicorn endure in medieval painting, not only in Europe but also in the Islamic world and China. The unicorn is the national animal of Scotland. Unicorns appear in mythology and folk tales from countries and customs all over the world. Several myths and tales narrate that unicorns can fly, even without wings. A Pegasus is another legendary creature that looks alike to a unicorn but has wings. 9th April is the National Unicorn Day celebrated in United Kingdom. During this day people dress up as unicorns by wearing costumes. In the next few years, many rituals' significant associations with unicorns developed to showcase a variety of predictions from the birth of a newborn prince to the approaching death of the person who views the creature. In the 1980s, the circus handled to connect together two horns of a white goat and shown it to audiences as unicorn. The contemporary times soon observed unicorns as friendly and magical creatures of fiction.
