It had been hiding in plain sight for centuries.

Looking over the oldest documents we have today, it's easy to get lost in their beautiful

simplicity and straightforward purpose.

The works of Plato, the Greek philosopher from the 4th century BC, have been pivotal

for over 2400 years.

And it's no wonder, really.

Plato's teacher was a guy named Socrates, and he himself became a teacher later on to

a man named Aristotle.

Legends, all of them.

But while we have scraps of writing from the other two men, Plato's complete works seem

to have done the unthinkable by surviving all the way to the present.

Which is why it's strange that after all this time, it was only about 10 years ago

that something new was discovered within them.

Looking over the oldest manuscripts we have, medieval documents carefully copied out by

scribes working with ink and vellum, researchers have found a pattern, a code, hidden in the

text.

To understand it, you need to know that ancient Greek music used a scale of 12 notes,

as opposed to our modern scale of 8, and what researchers have discovered is that Plato's

text is practically littered with patterns of 12.

In fact, perhaps to drive the point home, every twelfth line contains a reference to music.

It seems that Plato had something to hide.

Why?
