Meaningless. The leather wasn’t from Corinth, and neither the ancient Greek city nor any of its modern day namesakes in places like MS lend their name to any particular means of processing or grading leather. It was made up by the advertisers because they thought “leather” just sounded too plain. Interestingly, you can find bibles, briefcases, etc covered with “Corinthian leather” solely because of the credibility Ricardo Montalban’s commercials created.
As a materials testing engineer, I’ve come across car seats that are covered with “Corinthian Vinyl.” I guess the Corinthian Leather gimmick is a successful one.
By the way, Ricardo Montalban played the Grandfather in the movie “Spy Kids 3D, Game Over.”
One of his lines was “And don’t touch the wheelchair. It’s genuine Corinthian leather.”
I was almost rolling in the aisle. Stopped only by the realization that I was the only one laughing.
Close: it was made up on the set by Ricardo Montalban, who insisted that simply saying “rich leather” wasn’t enough to emphasize. After the fact the car company looked into the matter and found that they could use the name–so they did. This factoid appears in one of William Poundstone’s Big Secrets books, and Ricardo has answered this question in at least two different interviews he has given.
