We could tell that it was a stratified society, that nobility had better tombs than others, but we didn't really have a good sense of what was going on until we discovered this, which is the Rosetta Stone, which was discovered in 1799. And why, the reason why this is so valuable is it has the same text written in three different languages. It has it written in the hieroglyphs of the ancient Egyptians, and it has it written in a later script used in Egypt called Demotic Egyptian, and most importantly, it has it also written in Greek. And so historians were able to say, okay, we can now start to decipher what these symbols mean because we have a translation of them. And that's why it's one of the first civilizations where we're able to put the picture together, and hieroglyphics are one of the first forms of writing. But let's now go on in our journey through thousands of years of ancient Egyptian civilization. You, between the Old Kingdom and the Middle Kingdom, you have the First Intermediate Period, then you have the Middle Kingdom, and then you have the Hyksos, which are Semitic people, Semitic referring to their language being of the same family as Semitic languages like Arabic or Hebrew or Aramaic.
