This image shows a black-and-white design of a shield with a warrior in the center. The warrior holds a spear and stands on a cloudy base, with a helmet and armor that look heavy. Around him, the shield is packed with strange shapes—wings, animals, and tools like hammers and swords—all tangled in swirls. The top of the shield has a lion’s head spitting flames, and the whole thing looks like it’s made of metal. This kind of detailed carving is called *engraving*, where the artist etches lines into a surface. Check out technique: engraving to see how artists like this made their marks.
