read moreTimely puzzle. Interesting facts too — I hadn't realized DUE PROCESS derived from the MAGNA CARTA, nor had I known that Pope INNOCENT issued an annulment. That surely makes him famous — or at least infamous. (Note: it's a little weird that it was Pope INNOCENT III, while the entry led me to believe it was INNOCENT I. Harrumph.)

RUNNYMEDE isn't quite as interesting to me, as it doesn't have any trivia tidbits that go with it. I'm sure others will disagree. It is sort of cool how it interlocks into MAGNA CARTA and DUE PROCESS — never an easy task to achieve fortuitous interlock — but to me, the other themers had greater interest and impact.
That interlock also puts huge constraints on the grid, forcing big corners in the grid and not allowing very many long pieces of fill. Mike does well in the lower left, with SOLOMON / SO THERE adding to the quality of the solve. Those two nice answers at the price of only ESSO (which is still a big brand up in Canada)? Yes please! And SAMOVAR and PICASA are pretty nice as well.
In the lower right, I hitched on IN A SUIT. It takes up a precious 7-letter slot, and it felt arbitrary to me at first. Does that open the door for IN SLACKS, IN VELOUR, IN A THONG? Ultimately I decided I was being too picky though, as the phrase gets plenty of Google hits.
ULRIC crossing RUNNYMEDE is likely to give some people fits. I think it's more fair than not, as RUNNYMEDE felt familiar-ish to me, but that won't stop some people from grumbling.
Generally, it's a pretty clean puzzle, aside from a few RATER / AIRER things. I like to have all my gluey bits from different categories so they don't stand out as much, so it's too bad that these are both of the "add an -ER" variety.
I really liked the clue for OEDS. Funny to think of having a magnifying glass included in the sale! Again, an interesting piece of trivia to learn.
All in all, I liked the trivia. Those tidbits helped the puzzle stand out from other tribute puzzles.
