See the legend with your own eyes: Omfal in the Archaeological Museum in Delphi
According to another version, the omfal is called the very stone that Kronos swallowed instead of Zeus. And Varron, a Roman scientist and writer, proposed to recall the legend that the omphal was a tombstone over the grave of the Holy Snake of the Python and, presumably, he could be the point of contact of the two worlds – living and dead.
Thus, the stone acted as the center of the universe, “the umbilical of the earth”. You can look at the OMPAL at the Delphic Archaeological Museum. Who knows, perhaps the great Zeus, the father of all the gods, under the rule of which were the islands, Greece, ancient Hellenes, was actually touched by this block.
