Chapter 1804 New Evidence Discovered
“Huh? These two styles are not among the twenty-two styles of Qianlong?” Master Yang discovered the difference in the colors of these two brocades as soon as he got started.
"This is a real palace-style brocade from the Song Dynasty. Because the craftsmanship is a bit complicated, the Qianlong Dynasty made some simplifications." Zhou Zhi said: "Actually, it is still the basic pattern of the Eight Lantern Brocades, but with two square patterns. , two kinds of circular patterns, each filled with various group patterns. Each large coat of arms is divided into two tones, sapphire blue and beige. There are also two parallel lines of light blue between the large coats of arms. Connected, the texture and the large flower should be filled with various broken branches, flowers, birds, study and other patterns. This flower is very large, at least five feet by three feet in size. "
So-called. The tapestry is actually weaving patterns on a huge format, but it is not that there is only one picture on this huge format, but it is made up of countless identical pictures.
The pattern on a unit area is called a flower book.
There are also large and small flower books. The smaller the flower book, the simpler and more repetitive the patterns on the tapestry are. In the language of information science, the amount of information is small, and people can easily get bored of it.
The larger the flower book, the more independent content can be contained, and there will be less repetitions on the tapestry. The pictures will naturally be more varied and the amount of information will be greater, making people watch it again and again. I don’t feel tired either.
However, because the weaving method was too complicated, this weavers quickly gave up reluctantly. Later, after the technology of weaving flower books was lost, the creative skills were lost, and the weavers They only know how to "follow the script" and weave the tapestry according to the flowers.
Later, due to various reasons, the flower book was also lost. Brocade, China's most complex weaving craft that reached its peak in the Song Dynasty, inevitably declined.
Even after the Ming and Qing Dynasties, Nanjin rose again, and the Qianlong Dynasty obtained the "Twenty-Two Official Patterns" and tried their best to imitate them. For some of the extremely complex patterns, they had to make some subtractions to reduce the difficulty. It can be manufactured.
However, this work is assisted by computers, which is to divide the picture into very small elements and then read from the first element at the bottom right to the top left corner.
Then take the values of these elements by row. The single color set used in each row is the number of different colored silk threads that need to be used in this row. According to the law of weft, each grid only needs Put a silk thread above the warp and the rest below the warp, thus duplicating the flower book.
The remaining work is to convert the pattern book into a program that the computer jacquard machine can read, input it into the machine, and the imitation brocade can be woven.
However, in order to achieve the effect of imitating ancient silk, using a modern jacquard machine is definitely too precise and accurate. Therefore, Zhou Zhi used the Department of Archeology of Shu University to cooperate with Master Yang, and based on the four weaving machines unearthed from the Han Tomb in Laoguanshan, the capital of Shu. machine, The jacquard loom of Shu Brocade was restored, able to control two pieces of ground palm and eighty-four pieces of flower palm. Then a mechanical device controlled by a modern jacquard machine was built to control it. With the addition of Sanmian silk and ancient dyeing, it was finally successful. The Shu Brocade was imitated.
However, after getting the paintings of the Six Dynasties and Four Dynasties from Song Pi this time, Zhou Zhi realized that he had been hasty.
"Laoguanshan's brocade machine dates from the Han Dynasty. Although it can control more than 10,000 warp threads in a width of less than 50 centimeters, it still has not reached the peak level of palace-style jacquard brocade in the Song Dynasty seven or eight hundred years later." Zhou Zhi He shook his head and said: "After the computer After deducing, we found that in order to realize such a large flower book and such a complex pattern, the scale of the tapestry loom needs to be larger. There are still two pieces of tapestry, but the number of warps in each piece needs to be expanded to that of the existing loom. Twice, and the number of flower palms is even more One hundred and twenty-six pieces more."
Master Yang closed his eyes and thought for a moment: "Then it would have to be twice as wide and long as the current loom..." "Four times as long." Zhou Zhi. Said: "But we all think it is unlikely, because in that case The loom takes up too much space."
"Yes, but the ancients must have had a way to solve this problem?" Master Yang suddenly felt that he was a master of craftsmanship, not a master of mechanical design. The brain is about to boil.
"We have already guessed this. There are eighty-four pieces of flower palm in the Han Dynasty brocade loom, right? Each piece of flower palm is placed at the end of the loom, and eighty-four pieces is already very long." Zhou Zhi said: "So in the Song Dynasty, it will definitely be modified to meet the needs of designing more floral palms for more complex patterns."
"Comparing the two numbers eighty-four and one hundred and twenty-six, we can find that they have a common factor of forty-two. Eighty-four is twice forty-two, and one hundred and twenty-six is four Three times twelve.”
“So we guess that by the Song Dynasty, The flowers of Laoguanshan jacquard loom are no longer placed in parallel at the tail of the loom, but become three-dimensional. Three layers are designed at the tail of the loom, with forty-two flowers placed on each layer. Brown, in this way, not only accommodates more brown pieces, but also reduces the area occupied by the loom. The area has been reduced!”
“How wonderful!” Master Yang couldn’t help but rejoice: “Hahaha, that’s the only way! College students’ brains are so flexible!” It’s not difficult to transform it,” Zhou Zhi said with a smile. "It is estimated that Dean Jiang will come to see you soon."
At this moment, Zhou Zhi's big brother rang. Zhou Zhi looked at the caller ID: "Hey, Cao Cao, Cao Cao is here! Mr. Jiang It’s a coincidence, don’t you think?”
He pressed the call button: "Hey Dean Jiang... Ah, I'm back. I happen to be in the capital of Shu. I'm discussing the restoration of the Song Dynasty's Eight Damn Brocades with Master Yang... Why do you want to come with her? What's the matter? Ah? I know about the Niya ruins. It’s in the Hotan area. It’s a pity that I went to the north last time. Jiang was too busy to take a look... What? The actual arm in "Han Wu Shooting Dragon" was discovered! Okay, we'll be there soon!" What's going on?" Seeing Zhou Zhi's serious expression, several people were shocked.
Zhou Zhi pointed to the "Picture of Han Wu Shooting Jiao" on the white board which was pressed by magnet nails: "The biggest opinion raised by the experts during this appraisal is that the arm on the elbow of Emperor Wu of Han Dynasty has different characteristics in previous calligraphy and painting works. It has never been seen in archaeological objects, so although it is difficult to find faults elsewhere, the authenticity of this painting is still doubtful.”
"Yes." Fei Guan said: "Didn't you already say that when you introduced it just now?"
"Dean Jiang called and said that the physical object of this thing has been It was discovered that although it was Shu brocade from the Han Dynasty, it was found in an ancient tomb at the Niya site in Hotan, northern Xinjiang, thousands of miles away!”
