The arms of Prince Arthur at Carew Castle, Wales. Photo May 2003.

This is a close-up of Prince Arthur’s arms – the wider shot was Picture of the Week #8 and Catherine of Aragon’s were Picture of the Week #102. Arthur’s are the royal arms of the time (three fleurs-de-lis and three lions passant) with a three point label across the top, denoting him as the eldest son.

Here’s a full color version that makes it a little easier to pick out the details from the photo (image adapted from a file at Wikimedia Commons):
