The doctrine of the fall of man is extrapolated from Christian exegesis of Genesis 3. According to the narrative, God creates Adam and Eve, the first man and woman, in His own image. God places them in the Garden of Eden and forbids them to eat fruit from the “tree of knowledge of good and evil” (the fruit of which is often symbolised in European art and literature as an apple). The serpent tempts Eve to eat fruit from the forbidden tree, which she shares with Adam and they immediately become ashamed of their nakedness. Subsequently, God banishes Adam and Eve from the Garden of Eden, and places cherubim to guard the entrance, so that Adam and Eve will not eat from the “tree of life”.
The Book of Jubilees gives time frames for the events that led to the fall of man by stating that the serpent convinced Eve to eat the fruit on the 17th day, of the 2nd month, in the 8th year after Adam’s creation (3:17). It also states that they were removed from the Garden on the new moon of the 4th month of that year (3:33).
