Bell of King Seongdeok

The Bell of King Seongdeok is a massive bronze bell, the largest extant bell in Korea. The full Korean name means "Sacred (or Divine) Bell of King Seongdeok the Great." It was also known as the Emille Bell, after a legend about its casting, and as the Bell of Bongdeoksa Temple, where it was first housed.
The bell was commissioned by King Gyeongdeok to honor his father, King Seongdeok. However, King Gyeongdeok never lived to see the casting of the bell, as he died in 765 CE. The bell was finally cast in 771 CE, during the reign of Gyeongdeok's son, King Hyegong.

Now stored in the National Museum of Gyeongju, the bell was designated as the 29th national treasure of Korea on December 12, 1962. It measures 3.33 meters high, 2.27 meters in diameter, and 11 to 25 centimeters in wall thickness. The Gyeongju National Museum weighed it in 1997, and found that its weight was 18.9 tons.
When rung, it is said to have been heard from 40 miles away on a clear day.

Artistic characteristics
The bell is considered a masterpiece of Unified Silla art. It is unique among Korean bronze bells because of the presence of a small hollow tube near the hook. The whole structure, including its decorative elements, produces a wide range of sound frequencies; the tube absorbes high frequency waves, contributing to a distinctive beat.
The hook of the bell is in the shape of a dragon's head. There are many relief patterns on the bell, including are flower patterns along the rim and shoulder. There are also reliefs of lotus flowers, grass reliefs, and a pair of two apsarases (heavenly maidens). The striking point of the bell (dwangja) is also in the shape of a lotus and sits between two of the apsarases reliefs. The bottom of the bell is in a rhombic shape, lending it a look unique among bells of the Orient.

The inscriptions on the bell, over a thousand hanja, are a fine example of East Asian calligraphy and carving. They provide detailed information about the bell and why it was cast.
The column the bell hangs on is quite firm. Even a column made with the same diameter, out of modern alloy might bend by weight of the bell, yet the bell still hangs on an ancient column that has lasted for several centuries.

Legend
The bell is commonly known as the Emille Bell in both Korean and English. Emille, pronounced "em-ee-leh," is an ancient Silla term for "mommy".
According to legend, the first bell that was cast produced no sound when it was struck. The bell was recast many times but with no success. The king that had wanted the bell cast died after a while and his young son took over with the help of the queen. The son carried out what his father had started but still he didn't have any success. Later, a monk dreamed that if a child was cast into the metal, the bell would ring. The monk then took a child from the village and had her cast into the metal. When the bell was complete, the bell made the most beautiful sound when struck.
Some, however, believe the legend may actually be a modern invention, and that the story and name originated in the 1920s. A story that was published about the "Eomilne bell" or "Earmilne bell" (어밀네 종) may have been distorted in retelling. The most recent argument is that legend about other bell became confused with the legend of the Emille bell.
