What is the legend of Alexander's death?

There have been two local legends about the cause of Alexander's death. One is that when he was on an expedition to India, not far from Babylon, he met some priests who were proficient in astronomy and divination. They advised him not to go to Babylon, or he would run away. However, he did not stop moving forward. But since then, he has changed, his mood is gloomy and his expression is indifferent.

Once, he was cruising on the lake with a warship. Suddenly, a gust of wind blew his hat away and landed in the reeds, just on the tomb of the quaint King Brown. All the entourage and Alexander himself thought it was very unlucky.

The sailor who chased the hat boldly put it on his head when he came back from swimming, which further strengthened the sense of foreboding. Alexander was so angry that he killed the sailor at once. Soon, Alexander was seriously ill. After 13 days, finally in June 323 BC, Alexander, 32, who had been in office for 20 months, died in the evening.

Some people say that the death of the great emperor is just a coincidence. Because of the emperor's death, it is probably because of the hardships on the March and many battles, he was bruised all over and contracted malaria in the swamp.

Another legend is that Alexander died because someone put poison in his cup at the party. If this legend is true, then Alexander died not of natural causes, but of a conspiracy.
