Tracing the Rulers of Europe up to the Reign of Napoleon.
Antique map of Europe with chronological lists of all of the rulers of the major powers up to roughly 1809.
The map includes a number of theories about the origins of various peoples that seem quaint by modern standards. For instance: "L'Irlande fut d'abord peuplée par une Colonie d'Espagnols..." (i.e., "Ireland was first populated by a Colony of Spaniards...")
This is an interesting way to format the lineages of many thrones, but one can see how it could be confusing at the same time.
