Decide on which archetypal model you'll use to determine the archetypes. Several exist. These include archetypes from Carl Jungs' work, from the Enneagram personality theory or from Joseph Campbell's writings. Become familiar with each archetype in the model that you're using to create your archetype chart.
Create a grid with each character type; it's easiest to make the grid in a word processing document, because it's easily correctable. For example, if you're using the archetype model from Christopher Vogler's book "The Writer's Journey," make a row with boxes for each of the archetypes -- the hero, mentor, threshold guardian, herald, shape shifter, shadow and the trickster. The box in the upper left corner will be left blank. On the left column below the blank box, make at least four boxes. Make sure that you make each box in the grid big enough to make notes in the box. (See Resources for examples of literary grids.)
Write "Character Traits" in the second box below the blank box on the upper left hand side. You'll fill in the traits of each archetype in the box that falls directly below that type. For example in the second row, for the column marked "trickster" describe that character. Descriptions would include words like "the embodiment of mischief" and "the desire for change." Do this for each archetype, filling in the traits of the archetype in the box directly below the box that names the archetype.
Make a box for the name of the literary work that will be a part of your grid; this label goes in the third row on the list. For example, if you're making an archetype grid for Franz Kafka's "The Metamorphosis," write the name of the book in this box.
Remember to put in a space for the character names. Put this label in the fourth row. Label the box "Character Names" and fill in the row, writing in the name of each character corresponding to each archetype.
Add a final row for supporting notes -- use it for examples in the text that would support why the character fits that archetype. Of all the boxes, this one should be the largest, because you'll be referring to it often as you go through the text to find supporting characteristics and writing them in.
