prize7-2, Exercise 2: "Ptolemy's map of the world"

Model answer (check the details):

Why it misleads:
1. Ptolemy's Geography is a text with instructions and a list of coordinates. It is not a single drawing.
2. The maps in surviving manuscripts were drawn many centuries after his time, by copyists following the instructions, so they cannot be shown to be his work.
3. Printed "Ptolemaic" maps from the fifteenth and sixteenth centuries are Renaissance reconstructions, sometimes with new information added.

A more careful sentence:
"The Geography attributed to Ptolemy, written in the second century AD, gives coordinates and instructions from which maps were later drawn, and the maps that survive are copies and reconstructions from much later centuries."

Habit to keep: say what survives, who made it and when.
