It was God (the Logos, the Synthesis of the Host), who thus presiding over the Genii became the first Shepherd and Leader of men.[847] [pg 390] When the world had ceased to be so governed and the Gods retired, ferocious beasts devoured a portion of mankind. Left to their own resources and industry, Inventors then appeared among them successively and discovered fire, wheat, wine; and public gratitude deified them.[848]

And mankind was right, as fire by friction was the first mystery of nature, the first and chief property of matter that was revealed to man.

As say the Commentaries:

Fruits and grain, unknown to Earth to that day, were brought by the “Lords of Wisdom,” for the benefit of those they ruled from other Lokas [Spheres].

Now:

The earliest inventions [?] of mankind are the most wonderful that the race has ever made.... The first use of fire, and the discovery of the methods by which it can be kindled; the domestication of animals; and, above all, the processes by which the various cereals were first developed out of some wild grasses [?]—these are all discoveries with which, in ingenuity and in importance, no subsequent discoveries may compare. They are all unknown to history—all lost in the light of an effulgent dawn.[849]

This will be doubted and denied in our proud generation. But if it be asserted that there are no grains and fruits unknown to earth, then we may remind the reader that wheat has never been found in the wild state; it is not a product of the earth. All the other cereals have been traced to their primogenital forms in various species of wild grasses, but wheat has hitherto defied the efforts of Botanists to trace it to its origin. And let us bear in mind, in this connection, how sacred was this cereal with the Egyptian priests; wheat was placed even in their mummies, and has been found thousands of years later in their coffins. Remember how the servants of Horus glean the wheat in the field of Aanroo, wheat seven cubits high.[850]

Says the Egyptian Isis:

I am the Queen of these regions; I was the first to reveal to mortals the mysteries of wheat and corn.... I am she who rises in the constellation of the Dog.... Rejoice, O Egypt! thou who wert my nurse.[851]

Sirius was called the Dog-star. It was the star of Mercury or Budha, called the great Instructor of Mankind.
