Actually, I believe there is a possibility that there was a total of 18 legions. Not all of them completly described, but the highest number given to the legion that appears in any sort of Elder Scrolls lore is 18. And it's not just a simple numer, if there is 18th, there are others from 1st Legion to 18th Legion. Here's a trivia that assumes that there could be 18 legions in total and how strong they are if they are anything like Roman Legions. I found it on Imperial Legion page of this wiki.
 * If we assume that there are only 18 legions (mentioned above) in the Imperial Legion and a Legion numbered from around 4200 to 6000 troops like the Roman Legions did, then the Imperial Legion has anywhere from 75,600 to 108,000 troops or more if there are more Legions that are unmentioned. However, despite this, we cannot assume anything based on connotations created between The Elder Scrolls lore and outside information.
