Thyine Wood. Thyine Wood occurs in Revelation 18:12, where the margin has "sweet" (wood). There can be little doubt that the wood here spoken of is that of the Thuya articulata, Desfont, the Callitris quadrivalvis of present botanists. It is a cone bearing tree, and allied to the pine. This tree was much prized by Greeks and Romans, on account of the beauty of its wood, for various ornamental purposes. By the Romans, the tree was called citrus, and the wood was called citrum. It is a native of Barbary, and grows to the height of 15 to 25 feet.
