apple from. Blake's is obviously making a symbol and allegory in reference to the Bible and the Garden of Eden. Now the question is whether the Blake's tree symbolizes, from the Bible, the tree of good and evil or the tree of life. Does it even matter which tree was being symbolized here? These are questions that should be answered to fully understand the poem. Some knowledge of the Bible is in order to accomplish this.
             One tree from the Garden of Eden is the tree of good and evil; this is the tree from which Eve took the fruit (however not an apple) and shared it with Adam. Satan, in the form of a serpent, tempted Eve by telling her that she would be wise and know the difference between good and evil if she ate the fruit off the tree. The second tree is the tree of life which also contains fruit, that if eaten will bring the eater eternal life. Because Adam and Eve ate from the tree of good and evil, they were not allowed to eat from the tree of life and therefore banished from Eden.
