Harry's godfather Sirius Black is a fugitive wanted by the Ministry of Magic, who mistook him for a death eater. He escaped from Azkaban because it was an Ani maggs. It became a dog, escaped from the prison fence and was free. As the image of Arnie maggs, Dog Star Black Dog suits him very well. Sirills was originally the name of a star, and people usually call it DogStar. It has this nickname because this star is called the giant dog in its constellation. This star is named Sirius because it is the brightest star in the sky. In Greek, fat seirios means burning. ) This star has far-reaching significance in the wizarding world. It is the symbol of the goddess Isis, the religious and philosophical center of ancient Egypt, and the birthplace of most magic. Egyptians used Sirius to make their calendars, because the way Sirius operated was related to the seasons. On the first day of summer, it rises before sunrise. It was the New Year in ancient Egypt. He can also predict the annual flood of the Nile, which provides indispensable nutrients for all kinds of land where life grows. We still call the long and hot days in summer dogday (meaning dog days), because Sirius marks the arrival of summer. According to the ancient Egyptians, Sirius is not only of great significance to life on earth, but also, as a scholar who studies ancient Egyptian culture said, it is "the home of the dead". This star is so important that people should aim at its trajectory in the sky when building temples. An archaeologist concluded that the long tunnels and wind wells in the Great Pyramid enabled people to see the stars during the day, and that part of the sky they saw was where Sirius appeared. Another scholar said: "These gaps are to guide the dead." . The shape of Ani maggs, a Bigfoot black dog, is not only very suitable for Sirius Black in name, but also just right in many other aspects. Magic black dogs often haunt Europe and North America mysteriously. In Britain, people often see this kind of animals, calling them BlackShuck (Shuck comes from Anglo-Saxon scucca, which means devil), Old Shack (OldShuck), Shaggy Dog (ShuckyDog), ShugMonster and ShagDog. Staffordshire residents in central England gave them the name Sirius used: bigfoot. Some people say that these dogs specialize in guarding cemeteries and certain roads; Others said they wandered around the country at night. Witnesses said that they always appeared suddenly, sometimes suddenly next to people walking alone. They are generally bigger than ordinary dogs. They may suddenly disappear without a trace, or they may stand still and slowly disappear from your sight. Occasionally, they will appear as headless bodies. People almost always describe their eyes as big as two bells, "burning". Surprisingly, they generally don't make a sound. Scholars once thought that black dog was Satan's favorite form. Even people who are not easily nervous are generally afraid of black dogs. Many people think they are ominous signs of death. That's what Professor Trelawney told Harry. The first time he saw Sirius was a bad omen. He called the black dog ominous, which is also a very common name. Eyewitness reports can be traced back hundreds of years. A report in 1577 tells a very vivid story about a black dog visiting a church: "A big black dog suddenly appeared with a frightening flame, and some people in the church thought that the world was coming to an end. This dog, or the incarnation of Satan, ran to the end of the church at incredible speed, passed between two people kneeling there and broke their necks in an instant. " It can be said that it is a particularly horrible event, but not every time it meets a black dog. When people saw the black dog recently, it didn't seem as fierce as before. A scholar said: "A lot of evidence shows that black dogs are friendly (or at least harmless) rather than dangerous. In fact, black dogs are often very helpful to human beings. " Is this helpful black dog Sirius Black? We don't know yet.
