This verse is inscribed on a stone tablet next to a polo ground in Skardu Pakistan, north of Kashmir, near the fabled Silk Route. In one ancient sentence, it epitomises the feelings of many polo players today.

Many scholars believe that polo, in its antiquated form, originated among the Iranian tribes some time before Darius of Persia and his cavalry extended the Achaemenid dynasty rule to the greater Persian Empire.

Throughout Asian antiquity, from Japan to Egypt, from India to the Byzantine Empire, Polo and its variants were the nearest equivalents to a "national sport". However, as the great Eastern empires decayed and collapsed in the Middle Ages following their decimation by the Mongol hordes, so too disappeared the glittering court life of which polo was so important a part; and, the game itself was preserved only in remote villages.

The contemporary sport
Polo is now an active sport in 77 countries, and although its tenure as an Olympic sport was limited to 1900 -1939, in 1998 the International Olympic Committee recognized it as a sport with a bona fide international governing body, the Federation of International Polo.
Polo is, however, played professionally in only a few countries, notably Argentina, England, Pakistan, India, Australia, and the United States. Polo is unique among team sports in that amateur players, often the team patrons, routinely hire and play alongside the sport's top professionals.
Argentina dominates the professional sport, as its polo team has been the uninterrupted world champion since 1949 and is today the source of most of the world's 10-goal (i.e., top-rated) players.

The game

Rules
Polo requires two teams of players mounted on horseback to play the game. When playing outdoors each team has four players, whereas arena polo is restricted to three players per team. The object of the game is to score the most goals by hitting the ball through the goal.
A game is divided into periods, called chukkas-since 1898, from Hindi chakkar from Sanskrit chakra "circle, wheel", compare chakka -of 7 minutes, and depending on the rules of the particular tournament or league, a game may have 4, 6 or 8 chukkas; 6 chukkas are most common. Games are often played with a handicap in which the sums of the individual players' respective handicaps are compared. The team with the larger handicap is given free points before the start of the game.
The game begins with the two teams of four lined up each team in line forming two rows with the players in order 1, 2, 3, 4 facing the umpire in the center of the playing field. There are two mounted umpires on the field and a referee standing on the sidelines. At the beginning of a game, one of the umpires bowls the ball in hard between the two teams.

Player positions
Each position assigned to a player has certain responsibilities:
" Number One is usually the novice or weakest player on the team, but the position is one of the most difficult to play. Number One's job is to score goals as well as neutralize the opponents Number Four (defensive) player.
" Number Two needs a fast pony, a keen eye, and high maneuverability as his job is to get hold of the ball.
" Number Three is the tactical leader and must be a long powerful hitter to feed balls to Number Two and Number One as well as maintaining a solid defense. The best player on the team is usually the Number Three player.

" Number Four is the primary defense player and though he can move anywhere on the field, he often tries to prevent scoring.

Polo ponies
The term pony is purely traditional and the mount is actually a full-sized horse. A good pony should have docility, speed, endurance, and intelligence. It is said that the pony is 60 to 75 percent of the player's skill. Thoroughbreds were originally the only breeds used, but in the contemporary sport mixed breeds are common. Many of the best polo ponies are bred in Argentina and United States. Polo training begins at age four and lasts from about six months to two years. Ponies reach their peak at around age 10; but without any accidents, polo ponies may have the ability to play until they are 18 to 20 years of age.

Equipment
The basic dress of a player is a protective helmet, riding boots to just below the knees, and a colored shirt bearing the number of the player's position. Optional equipment includes knee pads and spurs, face mask, and a whip. The outdoor polo ball is made of plastic, but was formerly made of either bamboo or willow root. The indoor polo ball is leather-covered and inflated and is about 4? inches (11.4 cm) in diameter. The outdoor ball is about 3? inches (8.3 cm) in diameter and weighs about four ounces (113.4 g). The polo mallet has a rubber-wrapped grip and a webbed thong, called thumb sling, for wrapping around the hand. The shaft is made of bamboo-cane with a bamboo head 9? inches in length. The whole mallet weighs about 7 ounces and varies in length from 48 to 53 inches. The ball is struck with the side of the mallet rather than the edge.
Polo saddles are English-style similar to jumping saddles. The legs of the pony are bandaged from below the knee to the ankle to prevent injury. The pony's mane is clipped, and its tail is braided to prevent interference with the rider's swing.
