# Khipu Legend¶

Let's first start with a look at a typical Khipu web-page view. It's pretty self-explanatory, except for the terms Benford Match, K-Means, and Hierarchical Clustering. If these terms are unfamiliar to you, you may wish to review the Analyses page.

# Cords¶

## Cords¶

Cords consist of knots, and subsidiary cord clusters. A primary cord contains cords and cord clusters, who contain cords who contain.... And so it goes..

Here's an overview of cords in "wide" format. It shows cord attachments, cord twist, cord values, cord identifiers, etc.

## Cord Attachments and Twists¶

Cords are attached to the primary cord in one of four fashions

 Recto Cord Attachment (like a straight rectangle) with an S Twist Verso Cord Attachment (like a V) with an S Twist Up cord Attachment with an S Twist Unknown Attachment Type with an unknown Twist

Additionally, as noted above, cords can have one of two types of twists (S/Z) rendered as a slash over the cord attachment...

## Cord Colors¶

Cords have colors. But not just any color... They can be of the following forms:

 Solid Color Cord Barberpole Cord Mottled Cord Striped Cord Dahlberg Cord Missing Pendant Cord Missing Primary Cord

These are known as Ascher Cord Colors. A cord can be made up of one or more sections described by their Ascher cord colors.

# Knots¶

The Harvard Khipu Database has support for several types of knots and knot directions. Here is a knot legend of how I draw knots:

## The full Khipu¶

Right. It's probably about time we display a Khipu. Let's start with UR166 - Locke's canonical khipu that started it all.

And one of my favorite khipus because it's so pretty - UR233.  This time in wide format (showing why it's advantageous to have a tall format!)

Here is the original khipu, courtesy of the Museum in Berlin Germany:
