John Dee: Time traveler

Come back my old friend,
raise from the future
and give me the key
to unlock the past.

Delphic oracle: Nostradamus

With your clear vision,
you wrote the guidebook,
so every time you came back,
you could find the right path.

Master of time travel,
trained in the art of seeing,
put light on your timeless book,
so I can unveil the hidden meaning.
