When did Sirius hide in the rays of the Sun and was invisible? When did you have to pick the grapes?

1) When did Sirius hide in the rays of the Sun and was invisible?
2) When did you have to pick the grapes?
3) When did the holidays in honor of the god Bacchus begin?
4) When did the “new working year on earth” begin?

1) With the help of a stellar globe, we can easily find that this happens soon after the summer solstice. Then it was Sirius who was “burning and dried the head and the whole body”; then a terrible heat set in.
2) The grapes had to be harvested “when Orion and Sirius reach the middle of the sky, and the rosy-footed Aurora appears in the face of Arcturus,” that is, Arcturus will be visible in the rays of the rising Sun, and Orion and Sirius will then have the greatest height above the horizon (“in the middle of the sky”). Using the star globe, we find that it will be in early October, around October 12-15.
3) Around October 28-30.
4) “New working year on earth” or the beginning of field work was when the Pleiades and the regal Orion ceased to appear more, that is, The Pleiades and Orion become invisible, go along with the Sun. With the help of a star globe, it is easy to find that this happens in early May.
