ANQUI'NA (ἀγκοίνα). The collar by which the yard-arm of a vessel is fastened to the mast, technically called the "truss" by our sailors. Isidor. Orig. xix. 4. 7. Helvius Cinna ap. Isidor. l. c.

In the illustration (Anquina/1.1), which is copied from a fictile lamp, the anquina appears as a semicircular ring, or band of wood, or of metal, but it was usually made of rope. It received its appellation from the primary sense of the Greek word, which means a bent arm. The ἀγκοίνα διπλὴ, which is spoken of amongst the Greeks as employed for vessels of a large class, such as Quadriremes, &c., does not mean that the yard was fitted with two trusses, but that the truss was made of a double thickness of rope to bear the wear and tear proportional to the size of the yard.
