Answer:
Both are written using first person point of view.
Explanation:
Plymouth Plantation, written by William Bradford, is a book detailing the experience of the Pilgrims' Plymouth colony, which was located in Massachussetts, while Above the Ship is a book recounting the journey of a slave on a ship from Africa to Barbados.
This slave is, Olaudah Equiano, who was also the writer of the book. The two books were written in different periods: Bradford's book was detailing the experiences occurring during the 17th century, while Equiano's book was written in the 18th century.
Despite the difference in topics and periods, the two books share one similarity: It was written in first-person point-of-view. Bradford was the leader of the Plymouth colony and Olaudah himself is the slave who was on the ship.
