 car·bun·cle /ˈkɑrˌbəŋkəl/ 名詞
 癰
 Car·bun·cle n.
 1. Min. A beautiful gem of a deep red color (with a mixture of scarlet) called by the Greeks anthrax; found in the East Indies. When held up to the sun, it loses its deep tinge, and becomes of the color of burning coal. The name belongs for the most part to ruby sapphire, though it has been also given to red spinel and garnet.
 2. Med. A very painful acute local inflammation of the subcutaneous tissue, esp. of the trunk or back of the neck, characterized by brawny hardness of the affected parts, sloughing of the skin and deeper tissues, and marked constitutional depression. It differs from a boil in size, tendency to spread, and the absence of a central core, and is frequently fatal. It is also called anthrax.
 3. Her. A charge or bearing supposed to represent the precious stone. It has eight scepters or staves radiating from a common center. Called also escarbuncle.

 Carbuncle
    (Ex. 28:17; 39:10; Ezek. 28:13). Heb. barkath; LXX. smaragdos;
    Vulgate, smaragdus; Revised Version, marg., "emerald." The
    Hebrew word is from a root meaning "to glitter," "lighten,"
    "flash." When held up to the sun, this gem shines like a burning
    coal, a dark-red glowing coal, and hence is called
    "carbunculus", i.e., a little coal. It was one of the jewels in
    the first row of the high priest's breastplate. It has been
    conjectured by some that the garnet is meant. In Isa. 54:12 the
    Hebrew word is _'ekdah_, used in the prophetic description of
    the glory and beauty of the mansions above. Next to the diamond
    it is the hardest and most costly of all precious stones.
