Mistress Sofya La Rus recently filmed this video, edited and produced by Lord Ivo Blackhawk, which provides a brief introduction to two useful online resources: the Pictorial Dictionary of Heraldry at mistholme.com, and the SCA Heraldry Wiki at scaheraldry.info.
Jehanette de Provins, Her Majesty the Queen of Northshield, teaches classes on how to create armorial images using GIMP and images from the Book of Traceable Heraldic Art, and recently recorded a session for viewers at home.
GIMP is an open-source software package for pixel-based illustration, in the same vein as Paint and Photoshop. As a Mac user, I find the interface to be a bit clunky, but it’s free, it includes a lot of features, and it runs on a wide variety of operating systems, which makes it a useful tool.
Make sure to turn your volume up to follow the presentation!
This video provides a decent introduction to the medieval use of armory for a non-specialist audience.
This friendly video by Mistress Morgan Donner of An Tir with Baroness Alianora Greymoor provides a useful introduction to folks in the SCA who’re interested in registering some armory but don’t know were to start.
