Fine early copperplate engraved flowchart explaining the basics of navigation, published in London by Richard Blome.
The flowchart is surrounded by various instruments of use for navigation, including a cross-staff, compass, and globe. The flowchart starts with the "three parts of navigation," which are the materials, the lading of the ship, and the art of navigation. From there, one can get lost in the chart with its many forks and leads.
This antique print first appeared in Blome's 1686 The Gentleman's Recreation, which contains a series of depictions of various activities including hunting, painting, fishing, and other manly activities. The print is dedicated to Arthur Herbert, a Royal Navy admiral stationed in the Mediterranean.
