Final answer:
The historical context of the first Thanksgiving might be new to some, depicting the harsh conditions faced by the Pilgrims, their complex relationship with the Native Americans, and the non-traditional feast items such as venison, fish, and beer.
Step-by-step explanation:
Based on the authors' descriptions, one aspect that might have been new regarding the first Thanksgiving is the historical context of the event. William Bradford's narrative highlights the harsh conditions faced by the Pilgrims as they had no friends, inns, or houses upon their arrival in the New World. Moreover, it depicts the initially strained, yet evolving relationship between the Pilgrims and the Native Americans. Edward Winslow's account in Good News from New England mentions the challenges of settling among 'barbarous enemies' but also acknowledges the trustworthiness and intelligence of the Native Americans, particularly Squanto. The actual Thanksgiving feast, as described by Winslow and historian Nathaniel Philbrick, did not include stereotypical dishes such as pumpkin pie or cranberry sauce but rather featured venison, fish, fowl, and beer, with participants eating with their fingers and sprawling on the ground. These details might alter the traditional image of the first Thanksgiving that is often depicted in modern celebrations.
