@MadMarcus: I already answered that on the first page of the comments, but it should be in the mines (accessible from the north side of Monteriggioni's outer walls) after you renovate them.
@bullard: The only thing I can suggest is that you look over the screenshots, and if you see any locations that look unfamiliar, go and investigate them.
@Timgamer777: Check the maps again - there are 20 glyphs, listed and marked, with location descriptions and screenshots for each. (I double-checked after seeing your comment, and everything's there.) That's 5 in Florence, 1 in Monteriggioni, 5 in Tuscany/San Gimignano, 2 in Romagna/Forli and 7 in Venice. There aren't any glyphs in the mountains, so I hope you're not hunting for them there.
@crazytar: UK article, UK release dates. But we'll update with the US ones as well.
@JackSkellingtonSkin: I think the author was trying to focus on original PSN/WiiWare games, rather than falling back on PSOne Classics or Virtual Console games. But thanks for the observation.
@superjw701: Thanks for pointing those out. I fixed them, and just to be on the safe side double-checked all the feathers against their respective maps. I found that the map for CR5 was also wrong and, more embarrassingly, the location of SP3 was wrong on the large map. I've updated the small map images for Venice and the San Polo district, but the large ones will take a little longer.
I'd like to thank everyone for their patience and apologize for any inconvenience this has caused. Thanks also to iahtebrandon and superjw701 for pointing out specific errors - that was a big help.
@iahtebrandon: You're absolutely right; thanks for pointing out the errors. Regrettably, these things sometimes happen when we're working with lots of similarly named, similar-looking images, but I've updated SP7, CS3 and CS7 with the correct map images. If you (or anyone else) see any other errors, please leave a comment or message me directly.
@newbie1511: Thanks for pointing that out. I'll check the video again today; it's possible I marked something down wrong, and if I did, then I'll post a fix.
EDIT: I found the problem - the fourth step (move the fifth and first rings right 5 times) should actually be to move them LEFT five times. Sorry about that. I'll change it in the text. Hope that's not too late to help.
@raist: I think that one becomes accessible when you renovate the mines. The entrance is on the north side of the outer walls, behind where the villa is.
@lnksmartt: We're working on it. Our hidden-glyphs guide, with puzzle solutions, should be up tomorrow. Your patience is appreciated.
