What is unusual about calibans speech beginning be not afeard2?

Caliban's speech beginning with "Be not afeard" is unusual because it reflects a blend of poetic language and raw emotion, contrasting with the more formal speech of other characters in Shakespeare's "The Tempest." His Words convey a deep connection to the natural world and a sense of impending danger, revealing his complex character as both a victim and a creature of instinct. The use of archaic language and rhythmic patterns also emphasizes his role as a marginalized figure, highlighting themes of colonization and the struggle for power.
