“The forbidden fruit was an apple”

The verdict

Genesis 3 does not identify the forbidden fruit. The Hebrew text uses peri (פְּרִי) — simply fruit — with no species named.

The Hebrew Bible has a specific word for apple — tappuach (תַּפּוּחַ) — which appears in Song of Songs (2:3, 2:5, 7:8, 8:5), Proverbs 25:11, and Joel 1:12. Genesis 3 does not use it. If the writer had wanted to specify an apple, the vocabulary was available.

The apple identification is a later Latin Christian tradition.

Why the apple — one plausible explanation among several

The most widely cited explanation is a Latin pun, though it should be presented as one plausible contributor rather than a single cause. Jerome’s Latin Vulgate (late 4th century) became the standard Bible of Western Christianity for over a thousand years. In Latin:

• malum, -i (neuter, second declension) — apple, apple tree
• malum, -i (neuter, second declension) — evil, wrongdoing

The two words are homonyms. The same word means both apple and evil. In the Vulgate text of Genesis 3 the word for the tree of knowledge of good and evil is de ligno autem scientiae boni et mali (Gen 2:17) — using mali, the genitive of malum (evil). The malum pun may have contributed to the apple tradition in Western art; it is one plausible explanation among several for how the apple became the conventional depiction. Other contributing factors include the wide availability of the apple in European agriculture (so it was the fruit medieval European artists knew best), the apple’s symbolic role in Greco-Roman mythology (the apple of discord, the apples of the Hesperides), and the simple coincidence of medieval artistic convention.

By the medieval period, Western Christian visual art had settled on the apple as the standard depiction. Lucas Cranach the Elder, Albrecht Dürer, Michelangelo (the Sistine Chapel ceiling) all painted apples. The convention became so culturally dominant that English speakers eventually assumed the apple was specified in the text.

Milton’s Paradise Lost

John Milton’s Paradise Lost (1667) cemented the apple in the English-language imagination. Book IX of the poem repeatedly describes the fruit as an apple — Satan’s temptation speech to Eve, the act of eating, and the aftermath all use the word. Milton’s poetic authority shaped English-language reception of Genesis 3 decisively for the next 300 years.

Other species in Jewish and Christian commentary

The vacuum left by Genesis 3’s silence about species has been filled by Jewish and Christian interpreters with various guesses. Common candidates include:

• Fig — supported by Genesis 3:7, in which Adam and Eve cover themselves with fig leaves (the only plant named in the immediate aftermath). The fig is a plausible candidate from internal textual logic.
• Grape — proposed in some rabbinic commentary, partly because of the role of wine in later biblical narratives of disgrace (Noah, Lot).
• Pomegranate — has support in some early Christian commentary; the multi-seeded fruit has symbolic resonances.
• Citron / etrog — proposed in some Jewish traditions, given the citron’s ritual importance.
• Quince — proposed by some Hellenistic Jewish commentary.

None of these is named in the text. The Hebrew Bible’s silence appears deliberate; the text is interested in the act of disobedience, not the botany of the fruit.

What the text actually says

Genesis 3:6 (BSB): When the woman saw that the tree was good for food and pleasing to the eyes, and that it was desirable for obtaining wisdom, she took the fruit and ate it.

Three things about the fruit: good for food, pleasing to the eyes, desirable for obtaining wisdom. These are attributes the woman observes, not species identifications. The narrative is concerned with what the act of taking and eating meant — the violation of the prohibition — not with what was eaten.
