The concluding part of the last paragraph, especially certain final sentences like "When Columbus describes the world, it is in accordance with east being at the top. Columbus says he is going towards paradise, so his mentality is from a medieval mappa mundi," clearly indicates that he adopted an eastward orientation for religious reasons. It's worth noting, as mentioned in the previous paragraph, that mappa mundi were Christian maps from that era.
The passage discusses the evolution of map-making and the orientation of maps over time. It highlights various cultural preferences for map orientation, such as Chinese maps placing north at the top because the emperor resided in the north, Egyptians placing east at the top due to the sunrise, Islamic maps favoring south at the top to look towards Mecca, and Christian maps prioritizing east to align with the Garden of Eden. It traces the inconsistency in map orientations throughout history and suggests that the role of European explorers was not the decisive factor in standardizing north at the top. Jerry Brotton mentions that even famed explorers like Columbus described the world with east at the top. Consequently, the passage does not explicitly state what the primary factor was for adopting north as the top in modern maps. Therefore, the biggest contributory factor remains unstated in the passage, aligning with the correct answer:
The biggest contributory factor is not stated in the passage
The question is about identifying which early map-making conventions were most influenced by natural phenomena. Based on the provided comprehension, each culture had different preferences for map orientation based on natural phenomena, religious beliefs, and societal structures:
Early Egyptian Maps: The East was considered the top because it is where the sun rises, reflecting the influence of natural phenomena.
Early Islamic Maps: Favored South at the top because early Muslim cultures were north of Mecca and imagined looking up (south) towards it, influenced by religious orientation.
Early Chinese Maps: Despite having compasses, north was placed at the top due to the emperor residing in the north, and not because of natural phenomena.
Early Christian Maps: Often placed East at the top towards the Garden of Eden and Jerusalem in the center, also influenced by religious beliefs.
The correct answer to the question is early Egyptian maps as they were clearly influenced by the position of the sunrise, a natural phenomenon.
