prize7-3, Exercise 1: Four kinds of map compared

Model answer (check the details):

Kind              | Purpose                          | User                        | Accuracy                      | Style
Itinerary         | Show routes and distances        | Travellers, officials       | Good for distances, poor shape | Long strip, roads and towns
Mappa mundi       | Teach sacred and world history   | Clergy, pilgrims, scholars  | Not meant for navigation      | Circular, east at top, scenes and text
Portolan chart    | Plan sea voyages                 | Pilots, merchants           | Good Mediterranean coasts     | Compass lines, port names inland
Scholarly world map | Collect and organise knowledge | Scholars, rulers            | Varies, based on sources      | Coordinates, descriptive text

Takeaway: accuracy depends on purpose. Judging a mappa mundi by the standard of a portolan chart misreads what it was for.
