## Cadae is an experimental Western poetry form similar to the Fib. While the Fib is based on the Fibonacci sequence, the cadae is based on the number Pi. The word “cadae” is the alphabetical equivalent of the first five digits of Pi, 3.1415.[1]

## The form of a cadae is based on Pi on two levels. There are five stanzas, with 3, 1, 4, 1, and 5 lines each, respectively for a total of fourteen lines in the poem. Each line of the poem also contains an appropriate number of syllables. The first line has three syllables, the second has one, the third has four, and so on, following the sequence of Pi as it extends infinitely. [2]

## Rachel Hommel wrote an untitled “Cadaeic Cadae”, which uses the cadae form as explained above, and adds a level of complexity to it wherein the number of letters in each word represents a digit of Pi. [3]

## Michael Keith wrote a “Cadaeic Cadenza”, called “Near a Raven” in the Cadenza poetry form (also sometimes called Cadence), where the number of letters in each word represents a digit of Pi.[1]

## As a name, cadae is the alphabetical equivalent to the first five digits of the transcendental number pi (3.1415…). Pi, often represented as π, is a mathematical constant that is the ratio of a circle’s circumference to its diameter approximately equal to the number 3.14 or, to fourteen places, 3.1415926535897. In poetry, these numbers have been applied to line and stanza lengths, resulting in, yet again, a cross between haiku and sonnet. Here’s an example:

Butterfly

lands

on butterfly

bush.

A starving man eats

maggots, dies. When two days later he

is found

new maggots have begun

hatching in his mouth.

Which image

will you take to bed

like a lover for the first time

touching and turning it all through night?

Which will be there when you wake?
