Tree of Life

The Tree of Life is the highest and central tree of Eden, a visible pledge of immortality whose meaning changes decisively after the Fall. Initially it belongs to the abundance and harmony of Paradise; afterward, access to it must be forbidden, because Adam and Eve, already corrupted by sin, might use its fruit to live forever in their damaged condition. The tree therefore becomes both the image of lost life and the boundary that makes death a finite remedy rather than an endless curse.

Appearance and Place

The Tree of Life stands in the middle of the Garden of Eden, “the middle Tree and highest there that grew.” Its position gives it both physical prominence and symbolic centrality. It blooms with ambrosial fruit described as vegetable gold, distinguishing it from the surrounding trees while placing it within the garden’s overwhelming profusion of beauty, fragrance, color, water, and living growth.

Eden itself is represented as more than a cultivated enclosure: it is “a Heaven on Earth,” a divinely ordered landscape in which nature supplies every delight of sight, smell, and taste. Rivers rise from a sapphire fountain, divide into four streams, and nourish flowers, groves, lawns, vines, fruit-bearing trees, lakes, birds, and perpetual spring. Within this abundance, the Tree of Life marks the highest concentration of the garden’s promise. It is not merely one tree among many but the plant that makes immortality materially imaginable.

Satan’s Invasion and Misuse

Satan reaches the tree after entering Paradise by force. Finding the eastern gate obstructed by dense undergrowth, he refuses the proper entrance and leaps over the hill and wall, an act the narration associates with the intrusion of a thief into a guarded household. Once inside, he flies to the Tree of Life and sits upon it like a cormorant, using its height as a prospect from which to survey the living creatures below.

His occupation of the tree is deliberately perverse. He does not seek its life-giving virtue for restoration, nor does he contemplate the value of the plant itself. Instead, he sits there while devising death for those who live beneath him. The tree’s association with life is thus set against Satan’s destructive purpose: a source of immortality becomes a vantage point for plotting mortality. The contrast establishes a broader principle of the poem, that what is best can be twisted into the worst abuse or reduced to a merely instrumental use.

Relation to Knowledge, Sin, and Death

The Tree of Life grows beside the Tree of Knowledge of Good and Evil. Their proximity creates the garden’s defining moral structure. The Tree of Knowledge offers knowledge purchased at the cost of learning evil; the Tree of Life offers the possibility of continuing existence. After Adam and Eve eat the forbidden fruit, the problem is no longer simply that they have disobeyed. They now possess knowledge of good and evil while having lost the good condition in which such knowledge would not have brought ruin.

God therefore fears that the fallen pair may also reach out to the Tree of Life and eat, “and live for ever,” or at least dream of living forever. Immortality, once a gift joined to happiness, would now perpetuate a state corrupted by sin. The poem’s logic is not that life is intrinsically evil, but that endless life without restored moral and spiritual order would eternize misery. Death consequently becomes a final remedy: the fallen human being is removed from the possibility of endless corrupted existence so that, after a life tested by tribulation and refined by faith and faithful works, a renewed life may become possible.

The tree’s significance is therefore defined through contrast. It stands beside the Tree of Knowledge, life beside the knowledge that has brought evil; it belongs to Paradise, yet becomes inaccessible after Paradise is lost; it promises permanence, yet the postlapsarian order must pass through mortality before renewal. Its meaning is produced by these oppositions rather than by isolated description.

Guarding the Tree and the End of Access

After judging the human transgression, God commands Michael to remove Adam and Eve from the Garden and to impose perpetual banishment on them and their descendants. Michael is to choose flaming warriors from among the Cherubim and drive the sinful pair from the hallowed ground. The command does not end with expulsion. On the eastern side of the Garden, where the ascent from Eden is easiest, Cherubic watch is established together with a sword whose flame waves widely and frightens away every approach.

The purpose of this guard is explicit: Paradise must not become a receptacle for foul spirits, and the trees must not become prey to beings who could again use their fruit to deceive humanity. The Tree of Life is thus transformed from an available feature of the garden into a protected threshold. Its guarded status makes the Fall spatially permanent: the human pair do not merely leave a pleasant place, but lose access to the object that would have allowed their fallen condition to continue without limit.

Yet the expulsion is tempered by mercy. God sees Adam and Eve softened by tears and sorrow for their excess, and instructs Michael not to leave them disconsolate. Their access to the tree is closed, but their future is not wholly closed. The banishment preserves the possibility that mortality, repentance, faith, and eventual renewal may lead beyond the present loss.

Symbolic and Narrative Significance

The Tree of Life gathers the poem’s most consequential tensions into a single object. It embodies the original gift of immortality, the vulnerability of divine gifts to misuse, the distinction between continued existence and genuine blessedness, and the necessity of separating fallen humanity from an eternity of sin. When Satan perches upon it to plan death, the image becomes an emblem of inversion; when the Cherubim guard it after the Fall, it becomes an emblem of judgment; when death is described as a remedy before renewed life, the tree remains the absent standard against which the human condition is measured.

Its narrative function is consequently larger than its limited number of appearances. The Tree of Life helps explain why expulsion is required, why mortality enters the human future, and why the poem can present death not only as punishment but also as a boundary against the eternalization of corruption. Paradise is lost not simply because Adam and Eve must depart from its beauty, but because the living center of that beauty can no longer be safely approached. The tree remains at once a promise remembered, a danger prevented, and a sign that restoration must be achieved through a transformation of the human condition rather than through the simple recovery of an inaccessible fruit.
