Kudu horns are the largest and most striking shofar horns currently available. But another contender in the giant shofar category is a species of sheep. Not the famous American bighorn sheep, whose horns are indeed enormous, but are short and impractical for making shofars.
Rather the most massive horns are found on a wild sheep from the mountains of Asia. Standing up to four feet high and weighing in at 400 pounds, the argali (Ovis ammon) boasts a pair of prodigious horns. The longest on record measured 75″, two inches longer than the longest kudu horns.
The record-breaking horns were taken from a Marco Polo argali (Ovis ammon polii) although another rarer subspecies, the Altai (Ovis ammon ammon) has shorter horns, but which are even more massive.
The Shmoneh Esreh prayer refers to the shofar gadol (“the Great Shofar”) which will be blown to usher in the Final Redemption.
Likewise a verse in Yeshayahu mentions a “great shofar.” “And it shall be on that day that a great shofar shall be sounded, and those lost in the land of Assyria shall come, as well as those expelled to Egypt; and they shall bow down before G-d, on the holy mountain, in Jerusalem (Isaiah 27:13).
Invariably these references are not to a literal shofar, but the spiritual concept of shofar. Still, seeing and hearing the types of giant shofars mentioned above could help us visualize that day, may it comes speedily in our times.
