Constellation myth

In Roman mythology, Neptune had a son named Olin. O Ryan was born as tall and strong as his father. But he doesn't like living in the sea. Instead, he often comes to Shan Ye to climb mountains and hunt. However, he is Poseidon's son, so he can walk like a fly even at sea.

Accompanied by him all day is a hound named Sirius, who is as brave as his master. He always rushes to the front when hunting and always stands in front of Olin when he meets wild animals.

After a long time, Aolaiwen often met Di Anna, the goddess of the moon, while hunting. The two were quickly attracted by each other's elegance and superb hunting skills. Later, they often walked in the mountains together, climbed cliffs and climbed dangerous peaks, and talked about everything.

All this made Apollo, the sun god, very angry. He was afraid that his sister Di Anna would be like herself and Daphne. He knew that Di Anna was a stubborn girl, and persuasion could not impress her at all. Apollo was cruel and came up with a deadly trap.

One day, Olin "flew" at sea as usual, ready to go ashore to hunt. His whole body is submerged except his head.

Apollo and Di Anna happened to fly across the sea.

"Sister, the somebody else say you wear Yang kung fu. How about we have a game today? "

Di Anna thinks that only O 'Ryan can compare with her in archery, so she doesn't care about her brother!

"Well, what did you say?"

"Look, that little black spot is a stone, just shoot it." Apollo knew that his sister's eyesight was not as good as his own, and he couldn't see clearly what the black spot was.

"No problem!" His voice did not fall, but he heard a whoosh. A sharp arrow was neither biased nor inclined, and it was a small black spot.

"Elder sister, you really live up to your reputation. Brother, I never dare to compare with you again. " Say that finish, Apollo quietly left.

Di Anna was so proud that she landed on the sea and wanted to see the shooting target. But what she saw was O 'Ryan. He was hit on the head and lay quietly on the water. Before he could say a word to his sweetheart, he was already dead.

My favorite person died by my own arrow, and Di Anna fainted. Hearing the news of the tragic death of his master, Sirius cried bitterly all night. He didn't even look at other people's food, and in a few days he left with O 'Ryan.

This tragedy made Jupiter cry too. He collected Olin's body, lifted him to the sky and became Orion. He couldn't be together all the time, but after his death, he was finally with his sweetheart Di Anna.

Sirius also won Jupiter's sympathy with his loyalty, was promoted to heaven and continued to accompany his master. This is a dog. In order not to make Sirius lonely, Zeus also specially found a partner for him-a puppy. Jupiter knew that Olin liked hunting best before his death, so he put a small prey around him-the rabbit in heaven.
