Слайд 2

The Piri Reis Map

Слайд 3

A Portolan Chart

Слайд 4

The Portolan Grid
Equator and 45N are quite accurate
Map ends just below

45S
Intermediate Roses Might Represent Tropics (23.5 N or S) or 1/8 of a Hemisphere (22.5 N or S)

Слайд 5

The Portolan Grid
Radiating Lines are Compass Bearings
Meridians and Parallels are perpendicular
This

is a Cylindrical Map Projection

Слайд 6

Quality of Cartography
Europe and Africa
Coasts Pretty Good
Rivers Inaccurate
Brazil: Recognizable
North America and

South of Brazil: Very Poor

Слайд 7

Interpreting Ancient Maps
Any Ancient Map is Only as Good as Its

Depiction of Well Explored Areas
Things of Practical Use to Mariners (Capes and Islands) Often Exaggerated
Latitude is the Most Likely Parameter to be Accurate; Longitude Largely Guesswork
Imaginary Features Often Incorporated and Gaps Filled In

Map by Mercator, 1587

Слайд 14

Hendrik Hondius Map, 1630

Слайд 15

A Vicious Circle
Without Accurate Navigation, Accurate Maps Weren’t Necessary
Maps Were Largely

Schematic
Without Accurate Maps, there was no Point in Trying to Navigate Precisely
Coastal Charts, on the Other Hand, Were Valuable
Even Into Modern Times, Many Questioned the Need for Accurate Mapping

Слайд 16

What’s Missing?
The Pacific Ocean
Isthmus of Panama
Drake Passage
Deep Water: Was Never Dry

Land
No Evidence of Antarctic Ice Connection
Any Indisputable Feature of Antarctica
