We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.
** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**
Rule 2- Your post subject cannot be illegal or NSFW material.
Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-TIL posts.
Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.

Anyone know what Zipangri is? Could that be Baja California, or what?
Edit: Japan. Is apparently just off the coast of Mexico
This makes sense given the popular knowledge at the time. The reason Columbus set sail wasn't because he was a genius that knew the Earth was round when everyone else didn't. We knew the Earth was round since antiquity. I can't remember who^1^, but some ancient Greek had calculated the circumference of the Earth using the angle of a shadow, distance to a ~~equinox~~ solstice, and simple trigonometry. They guy was less than 5% off with his rudimentary calculation, which is impressive considering that he paid some dude to measure the distance between two towns by walking it. Anyways, the Western Europeans thought that Japan was farther east, somewhere around where the words "Terra florida" are on this map if I recall correctly from memory. When the Niña, Pinta, and Santa Marimba (party boat! jk, it was Santa Maria named after the "virgin") landed on the most beautiful land that human eyes had ever seen, they knew they hadn't landed on Zipangri/Cipangu/Japan. Instead, they thought they had landed on some island off of India, which is why they called the locals "Indios" (Indians). Anyways part 2, they thought that Japan was much further east than it was. I imagine that since they hadn't found it for this map yet, they though it must be right out of sight of the western coast of North Vespucci (America).
What I'm curious about is that 7448 inflating archipelago. Anyone have an idea on what that's about?
1: The dude was Eratosthenes. Thanks, @[email protected]!
It's not "inflating", it's "insularum" (they also used to use the tilde as a shorthand for m and n), using the old long s
