Mission to London (1)

Hmm... what did I promise to give Raleigh?

First, the vitamin supplements and the watch.

These are items for navigation.

Vitamin supplements are essential. Sailors of this era died en masse from mysterious ailments, and the fact that it was scurvy caused by vitamin C deficiency was only discovered centuries later.

The watch and nautical chart are likewise crucial.

It would take until the 18th century for John Harrison to develop a clock that works accurately at sea. And until then, there were no clocks that worked reliably without error at sea.

But with just this wristwatch, everything changes. If you can tell time on a ship, you can determine longitude, and if you know the longitude, you can determine your position at sea.

It's a privilege no sailor of this era enjoys. That's why Lord Raleigh's eyes rolled back.

And a map made with 21st century technology? That goes without saying.
