Symmetry in the houtian bagua

(Click pictures to enlarge)

At first glance the houtian bagua 後天八卦trigram circle seems devoid of any symmetry. It seems as if the trigrams follow each other in a random order, and that there is no logic behind it. But if we look at the circle in the way we are taught in the Ten Wings, namely as an order linked with time, patterns start to emerge.

In the Ten Wings the trigrams are described in the sequence of the houtian circle, starting with Zhen and going clockwise, ending with Gen . The trigrams are supposed to follow each other in time – Zhen and Xun are linked with Spring and morning, Li and Kun with Summer and midday, Dui and Qian with Autumn and evening, and Kan and Gen with Winter and midnight. In time, the trigrams change in each other – Zhen changes in Xun, Xun changes in Li, etc.

We can mark these changes in every trigram. When Zhen changes in Xun, all three lines change. When Xun changes in Li, the lower and the middle line change, etc. We can mark the lines that are going to change in every trigram:

In Zhen 3 lines change to make Xun; in Xun 2 lines change to make Li; in Li 2 lines change to make Kun, etc. There is a balanced sequence in the amount of changing lines: 3 – 2 – 2 – 2 – 1 – 2 – 2 – 2. The major change takes place in Zhen: the start of a new year and a new day.

It seems as if the line created by the pair ZhenDui, the symbols of sunrise and sunset, divides the circle in half. The trigram pairs created in this way are each others pangtonggua 旁通卦 and fangua 反卦. A pangtonggua is the inverse of a trigram: a yin line becomes a yang line and vice-versa. A fangua is the trigram turned upside down.

Xun is the combined pangtonggua and fangua of Gen; Li is the ptg and fg of Kan (although the fg is not visible because the trigram is symmetrical); Kun is the ptg and fg of Qian; Dui is the ptg and fg of Zhen.

If I would switch the trigrams Zhen and Gen the circle would even be better: that way every trigram would be opposed to its ptg, and no fg would be necessary. Also the changing lines sequence would become more symmetrical: 1 – 2 – 2 – 2 – 1 – 2 – 2 – 2. It surely makes room for speculation…..

A Mulan in the Yijing

Through several channels the character of hexagram 44, gou 姤, has been brought to my attention. On Hilary’s forum there has been some discussion about it, mainly stirred by the view of Margaret J. Pearson as expounded in her article Towards a new reading of hexagram 44 in The Oracle Vol. 2, no. 11 (September 2000). In this article she says,

“I suggest that this character be read as ‘queen’ , as did Karlgren (GSR 112) or, more precisely, ‘the bride of the ruler’ (king or duke) 王后, as in the Chunqiu (Spring and Autumn Annals)”.

National Palace Museum Taipei, Taiwan

One of my favourite sites is the site of the National Palace Museum in Taiwan. Beautiful pictures and a lot of information. Check for instance the section with past exhibitions. My favourite one is A Special Exhibition of Bronze Inscriptions from the Western Chou. The introduction is a good entry into the world of bronze inscriptions. Other ones are Ancient Writing from the Ruins of Yin (about oracle bones) or a Special Exhibition of Shang Period Ritual Bronzes.

I can spend hours on sites like this.

 

Shanghai Museum Chujian Zhouyi

Books can make me happy, but the book I received today thrills me with excitement. I finally received a copy of the Chujian Zhouyi, aka the Shanghai Museum manuscript of the Zhouyi (to read more about it see Edward Shaughnessy, A First Reading of the Shanghai Museum Bamboo-Strip Manuscript of the Zhou Yi, forthcoming). It is the oldest (but not complete) copy of the Zhouyi we have today; it is estimated around 300 BC.

In the Spring of 2004 the Chujian Zhouyi was published. Shaughnessy writes about this book:

(…) this third volume is sumptuously produced. It begins with a two-part section of photographs of all the strips: first, half-size full-color photos of all of the strips arranged in what the editors believe was their original order, and then enlarged full-color photos in which each strip occupies a single page. This introductory section is then followed by an 83-page section of transcription and detailed commentary written by Pu Maozuo 濮茅左, a senior curator at the Shanghai Museum. As in earlier volumes, this section begins with a brief overview of the text, including its physical properties, format, general paleographic considerations, and, in this case, the place of the manuscript in the textual history of the Yi jing. This section proper consists of strip-by-strip presentations of the text. Also as in previous volumes, each strip is introduced by yet another photograph, this one full-size and black-and-white (though certain symbols that are red on the original strips seem to have been hand-colored in these photographs). There then comes a detailed description of the physical characteristics of the strip, including especially notation of any breaks and/or rejoinings. Finally comes a phrase-by-phrase discussion of the text on the strip, each of which is followed by how the phrase reads in the silk manuscript of the Yi jing that was discovered thirty years ago at Mawangdui 馬王堆, in Changsha 長沙, Hunan, and also how it reads in the received text. The presentation of the Zhou Yi includes also two appendices. The first, 35 pages long, is a line-by-line comparison of the Shanghai Museum manuscript, the silk manuscript from Mawangdui, and the received text of the Zhou Yi; entries for both the Shanghai Museum and Mawangdui manuscripts include both photos of the original manuscript and also direct kaishu 楷書 transcriptions. The second appendix, 10 pages long, is a study of six different black and/or red symbols that are included with each of the hexagram texts of the manuscripts. Publication of the volume was delayed apparently because of a flaw in the coloring of these symbols in the first print-run, necessitating the withdrawal and reprinting of the entire edition. This is a manifestation of the care that has gone into the editing and publication of all of the Shanghai Museum manuscripts. Although this volume, like most paleographic publications, has already met with various types of criticism, mainly from scholars in China, the scholarly world is surely much in the debt of all those who have worked so hard to make these manuscripts available.

The book measures 44 x 30 cm in size, the quality of the paper, printing and binding is excellent, in all, it is a pleasure to look at. I don’t even dare to read it, afraid that I will spoil the pages!

The next few weeks I will examine the book and the manuscript carefully. If I find anything interesting (of course I will) I will let you know.
