The Livro do Armeiro-Mor (Book of Great Armigers) was painted in Portugal 1506-09 by Jean Du Cros.
As with a number of other period armorials, it has been photographically digitized at high resolution, but the only publicly-available source for these scans is a “click to pan and zoom” web interface operated by the Portuguese Archives Network, which is hard to flip through rapidly, and can’t be accessed when offline at an event.
Gunnvôr silfrahárr has a PDF version posted which has a very helpful name index, but the images have been compressed, so the quality is significantly lower than the original scans. Some of the pages are available at the Wikimedia Commons, but the resolution isn’t as high, and the collection is incomplete.
So, I downloaded each of the full scanned images and combined them into PDF file. There wasn’t any technical wizardry involved — just clicking the download link 277 times.
As with the previous rounds, I’m posting a compressed PDF here (13 MB) and will share the full size PDF or JPEGs (210 MB) by request.
