Historical context<\/b><\/h2>

This striking bone sculpture reproduces <\/span>Zhang Heng's seismograph, constructed in 132 B.C. <\/span>Zhang Heng was a prominent scholar during the <\/span>Han Dynasty. The reign of the Han Dynasty was a period of prosperity and a significant spread of monetary circulation. From the reign of Emperor Wu (141-87 B.C.), the imperial court officially promoted, in both education and politics, Confucianism combined with the cosmology of later scholars such as Dong Zhongshu. During the Han Dynasty, there were significant scientific and technological advances. Paper, the rudder, the use of negative numbers, plastic maps, the hydraulically powered spherical astrolabe and the seismograph described above, which used an inverted pendulum, were invented. <\/span><\/p>

Symbolism<\/b><\/h2>

In <\/span>Chinese culture The dragon symbolizes power, the heavens, the order of the cosmos and elemental forces, while the toad represents earth, water and the cyclical nature. Their co-occurrence reflects the harmonious combination of heaven and earth, science and spirituality - the fundamental principles of Chinese philosophy. <\/span>

Biography of the creator of the first seismograph<\/b><\/h2>

Zhang Heng (78-139 BCE)<\/b> was one of the most prominent scholars of the Han Dynasty era - an astronomer, mathematician, geographer and designer of precision scientific instruments. In 132 he developed the world's first working model of a seismograph<\/b>, a device capable of detecting earthquakes and indicating the direction of their epicenter. He also created a hydraulically driven armillary sphere<\/b>, one of the earliest astrolabes of its kind, and developed innovative cosmological models to describe the relationship between the heavens and the earth. His scientific activities were in harmony with the cosmological concepts of the era, which - within the framework of official Confucianism - emphasized the harmony between the forces of nature and the order of the cosmos. Thanks to his extraordinary versatility and innovative approach, Zhang Heng is today considered one of the greatest inventors and thinkers of ancient China. <\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"

Seismograph model made of natural animal bone (imitating ivory), engraved and stained.

The device was about 2.5 meters high and made of bronze. In the mouth of each of the eight dragons was a small iron ball, balancing between the teeth. Inside the body of the device was a metal pendulum, set in motion by the vibrations of the earth. A lever system activated by the pendulum opened the dragon’s mouth, and the falling ball fell into the frog’s mouth.
