Word of the Day: I CHING COINS (41A) —

The I Ching or Yijing [...]  usually translated Book of Changes or Classic of Changes, is an ancient Chinese divination text that is among the oldest of the Chinese classics. The I Ching was originally a divination manual in the Western Zhou period (1000–750 BC). Over the course of the Warring States and early imperial periods (500–200 BC), it transformed into a cosmological text with a series of philosophical commentaries known as the Ten Wings. After becoming part of the Chinese Five Classicsin the 2nd century BC, the I Ching was the basis for divination practice for centuries across the Far East and was the subject of scholarly commentary. Between the 18th and 20th centuries, it took on an influential role in Western understanding of East Asian philosophical thought.

As a divination text, the I Ching is used for a Chinese form of cleromancy known as I Ching divination in which bundles of yarrow stalks are manipulated to produce sets of six apparently random numbers ranging from 6 to 9. Each of the 64 possible sets corresponds to a hexagram, which can be looked up in the I Ching. The hexagrams are arranged in an order known as the King Wen sequence. The interpretation of the readings found in the I Ching has been discussed and debated over the centuries. Many commentators have used the book symbolically, often to provide guidance for moral decision-making, as informed by Confucianism, Taoism and Buddhism. The hexagrams themselves have often acquired cosmological significance and been paralleled with many other traditional names for the processes of change such as yin and yang and Wu Xing. [...] 

The most common form of divination with the I Ching in use today is a reconstruction of the method described in these histories, in the 300 BC Great Commentary, and later in the Huainanzi and the Lunheng. From the Great Commentary's description, the Neo-Confucian Zhu Xi reconstructed a method of yarrow stalk divination that is still used throughout the Far East. In the modern period, Gao Heng attempted his own reconstruction, which varies from Zhu Xi in places. Another divination method, employing coins, became widely used in the Tang dynasty and is still used today. In the modern period; alternative methods such as specialized dice and cartomancy have also appeared. (wikipedia)

This isn't much of a theme. It's just ... four of the same kind of thing. Four things from the same general category. It's like BUS CAR TRUCK VAN. Or four baseball player names. Or author names. Or U.S. states. True, it's drawing from a category with fewer items in it (not sure how many prognostication devices there are in the world). But still, this is just "Here are four items that are used for similar purposes." That doesn't really get us to Theme Territory. There's no hook, no revealer, nothing at all to make it make sense as a theme. The theme clues are just ... regular crossword clues!?!? I mean, yes, they're wacky "?" clues, but we see those Every Day. The first one was actually used by this very outlet back in August of 2017 (TAROT CARDS = [Observation deck of the future?]). The cluing is giving us nothing in terms of making the theme cohere. I'm baffled at how this made the grade. I would also say that I CHING COINS feels like a strong outlier here, familiarity-wise. I had to read way way down the wikipedia "I Ching" page to find anything about "coins," and even then, it was just in passing (turns out "I Ching divination" has its own separate page). I think of the I Ching as a text. I know it's used in various rituals of foretelling, but how those rituals are performed, pfft, no idea. Apparently, there's no one way. There are lots of ways. One of those ways involves coins. It seems. I did not have to wonder about how the other three theme answers worked. At all. But I CHING COINS is not a phrase I've ever heard. As a result, this puzzle was briefly Not Easy, which I should be grateful for, but it's a mild bummer to have the only difficulty in a puzzle concentrated on just one answer. I feel like what we've got here is a first draft of a theme idea, but there's nothing to elevate it to real Theme status. No snap, no pop. Just a list of things. Disappointing.
