The Mainsail of Squid-people is a dramatic poetic form intended to express pleasure with Dedie the Merfolk Bull-sharks, originating in The President of Sanctifying. The rules of the form are applied by poets to produce individual poems which can be recited. The poem is two septets. Use of consonance is characteristic of the form. Forms of parallelism are common throughout the poem, in that certain lines often contrast underlying meaning and they reverse grammatical structures. Each line has seven syllables.
