Final answer:
The phrase refers to a form of dance or performance with cultural significance, possibly related to African American Steppin'. Such movements often have historical and community meanings, reflecting identity and resistance.
Step-by-step explanation:
The statement "The astonishing whites of the soles of his feet rise and salute us on the turns" likely refers to a form of dance or ritualistic performance that involves particular movements of the feet. In this context, the salute could be a metaphorical expression to convey the importance or cultural significance of these movements. Within various African cultures, dance movements often carry historical and cultural meanings, which might be symbolized through the action of the feet rising and 'saluting.'
For example, African American Steppin' is a tradition where the movements have specific connotations and histories associated with them. This is mirrored in cultural traditions such as gumboot dancing, which has its roots in South African mines where communication was achieved through rhythmic patterns created by slapping boots and chains. Such dance forms not only entertain but also carry the weight of expressing identity, history, and community.
The passage suggesting a salute could also symbolize resistance or proclamation, as seen in depictions of historical figures expressing pride in their lineage or identity in the face of oppression. This is a common theme within African American literature and art, where the expression of culture through dance and physical gestures holds significant meaning.
