Horn of Gondor
Made from a horn of a Kine of Araw (an ox from Rhûn), the Horn of Gondor also referred to as the Great Horn, was an heirloom of the stewards of Gondor in J. R. R. Tolkien's fictional universe of Middle-earth.
The horn was made by Vorondil the Hunter during the 19th or early 20th century of the Third Age. Vorondil hunted oxen all the way to the Sea of Rhûn and fashioned the horn out of one of the oxen's horns. Since then it had been passed down through the line of the Stewards of Gondor.
The horn was beautiful and loud. Its magnificent sound would momentarily paralyze enemies with fear, and would usually be followed by aid from allies.
During the War of the Ring, Boromir, son of Denethor, possessed the Horn of Gondor, just as it had been borne by the eldest son of the Lord Steward of Gondor for centuries. It is said that if the horn was heard anywhere within its borders, Gondor would come to the owner's aid.
When Boromir was slain early in The Two Towers, the Horn of Gondor was cleft in two. The horn later washed up upon the banks of the Anduin river, where it was discovered by his brother, Faramir. This is how Denethor learned of his son's death.
