Final answer:
The ears and tail of Edward, likely an artifact or artistic representation, may have been made from materials like wood, lapis lazili, and gold, with a particular focus on decorated bull's ears with earrings.
Step-by-step explanation:
The question concerns the materials used to make the ears and tail of a figure, most likely from a historical artifact. The given information suggests that Edward, or the figure in question, could refer to an artistic depiction where bull's ears are highlighted.
From the context, we can infer that this depiction may have been heavily adorned, possibly part of a grand artifact or artwork. The discussion on materials such as lapis lazuli and gold, as well as mentioning the use of plaster of Paris to preserve decorations from decayed wooden parts, suggests we are dealing with a historical artifact or representation.
Considered specifically, the ears and tail of such a figure may have been crafted from a variety of materials, as mentioned in the snippets: wood, gold, semi-precious stones, and possibly other now-decayed organics. Given the context of earrings being mentioned, we could conclude that the ears, at least, were considered an important decorative element of the piece.
