The size of the official seal of the Song Dynasty

The characteristics of official seals in the Song Dynasty included the simplicity of materials, the increase in the size of the printing surface, the widening of the outer frame of the seal, the use of the "nine-fold seal script" font, the inscription of the time on the back of the seal, and the completeness of the system. The official seals of the Song Dynasty were mainly made of copper. Other than the emperor's imperial treasures, which were made of jade and gold, the other official seals were basically made of copper. The size of the printed surface became larger and larger, with a side length of about 45 to 55 millimeters. The outer frame of the seal also became wider and wider. Most of the official seals used the "Nine Stacks Seal Script", which meant that the number of strokes was more twisted. There was a time stamp on the back of the seal, which recorded the time of casting the seal and the name of the casting organization. In addition, the official seal system of the Song Dynasty was also very complete, including the establishment of a special printing agency, the Ministry of Rites responsible for the management of official seals, and the establishment of a strict management system. Generally speaking, the official seals of the Song Dynasty had their own characteristics in terms of form, quality and system.

The size of the ancient official seal had changed over time. From the Qin and Han Dynasties to the Northern and Southern Dynasties, the size of the official seal was roughly 20 mm to 30 mm square. However, by the Sui and Tang Dynasties, the size of the official seal had increased to 50 mm to 60 mm square. The size of the official seal of the Ming Dynasty was generally 10-12 cm square, and the handle of the seal was gradually increased. Some were as high as 8 cm, and the edge of the seal was also gradually widened. The official seal of the Song Dynasty was roughly 5 to 5.5 centimeters in size. Therefore, the size of the ancient official seal changed in different periods.

In addition, the literati of the Song Dynasty also began to display their elegance and literary cultivation on the seal. Various nicknames, idioms, and cultural symbols often appeared on the seal. In general, the seals of the Song Dynasty had various and rich characteristics in terms of shape, content, use, and artistic form.

In the Song Dynasty, the development of seals had a new feature, from the simple creation of craftsmen to the participation of many literati. This was due to the development of epigraphy and philology at that time, as well as the rise of calligraphy and painting seals and the popularity of literati collecting calligraphy and painting.

The date and unit of production of the chiseled seal on the back of the Song Dynasty official seal could be used as a symbol to identify the Song Dynasty official seal. During the Song Dynasty, there were political powers established by ethnic minorities, and their official seal systems were influenced by the official seal system of the Song Dynasty to varying degrees. Of course, they also had their own characteristics. The Nine-Fold Seal Script was a special type of seal script that was popular in the Song Dynasty. In general, the seals of the Song Dynasty were diverse and rich in shape, content, use, and artistic form.
