This adjective describes objects made from the wood of the θύον tree, an aromatic North African conifer (likely Tetraclinis articulata, called citron or sandarac wood). Ancient sources prized this wood for its beautiful grain, pleasant scent, and durability, using it for expensive furniture and decorative items. Revelation 18:12 lists "thyine wood" among the luxury commodities no longer purchased in fallen Babylon. The translations vary: English "citron," Spanish "olorosa" (fragrant), German/French "Zitrusholz" (citrus wood), reflecting uncertainty about the exact botanical identity while preserving the sense of rare, aromatic, costly wood.
