There is an astonishing number of proverbs and aphorisms which use apples as their key ingredient. A small selection of the best known would include:

  • Don’t upset the apple cart.
  • An apple a day keeps the doctor away.
  • One bad apple spoils the bunch.
  • Adam ate the apple, and our teeth still ache.
  • An apple never falls far from the tree.
  • Don’t upset the apple cart.
  • As sure as God made little apples.
  • She’s the apple of my eye
  • Apples ain’t apples.

It is hard to know why it is that apples have insinuated themselves so far into our language.

A Biblical connection is the likely explanation. It is commonly thought that, consigned to the Garden of Eden, Adam and Eve misbehaved by eating an apple from The Tree of Knowledge.

However that may be, the Bible offers no support at all for the idea that the Tree of Knowledge was an apple tree. The King James version of the Bible has only a few references to apples. They are mostly the metaphorical “apple of the eye”. So, taking them in the order of their appearance, we find:


10 He found him in a desert land, and in the waste howling wilderness; he led him about, he instructed him, he kept him as the apple of his eye.


Psalm 17

8 Keep me as the apple of the eye, hide me under the shadow of thy wings,


Chapter 7

  1. Keep my commandments, and live; and my law as the apple of thine eye.

Chapter 25

  1. A word fitly spoken is like apples of gold in pictures of silver.

Incidentally, apple of the eye is a reference to the pupil through which the dark retina is seen. It was once thought that the pupil was a solid, globular body.

So, Deuteronomy contains the first reference to an apple, and even then it was a reference to the pupil of the eye. The story of the Creation and the Fall appears in Genesis. Here is part of Genesis Chapter 3:

2 And the woman said unto the serpent, We may eat of the fruit of the trees of the garden:

3 But of the fruit of the tree which is in the midst of the garden, God hath said, Ye shall not eat of it, neither shall ye touch it, lest ye die.

4 And the serpent said unto the woman, Ye shall not surely die:

5 For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil.

6 And when the woman saw that the tree was good for food, and that it was pleasant to the eyes, and a tree to be desired to make one wise, she took of the fruit thereof, and did eat, and gave also unto her husband with her; and he did eat.

No mention of apples. And that is not surprising: apples are generally found in temperate climates. The books of the Old Testament were written in much warmer places, and they were written in Hebrew and Aramaic so there is scope for adjustments in translation. One view is that the Tree of Knowledge was a reference to the pomegranate tree. OED2 says apple is:

“…part of the name of a large number of fruits; as apple Punic, obs. name of the pomegranate; apple of Sodom, or Dead Sea Fruit, described by Josephus as of fair appearance externally, but dissolving, when grasped, into smoke and ashes; a ‘traveller’s tale’ supposed by some to refer to the fruit of Solanum Sodomeum (allied to the tomato), by others to the Calotropis procera

So an apple Punic is a pomegranate. Punic is a reference to Phoenecia (Carthage). The name for the Phoenecians comes from the Greek Phoinikes (‘purple people’) because of Tyrian Purple – a fabulously expensive dye for which they were famous. Incidentally, the word pomegranate (the fruit of the tree Punica Granatum) literally means apple with many seeds, so it is quite plausible that the pomegranate was the fruit originally understood as coming from the Tree of Knowledge. The pomegranate is native to Carthage.

Still, the apple now refers to a fairly specific kind of fruit and, despite its many varieties, is not readily confused with a pomegranate.

Apples were originally sold by the costermonger (originally meaning apple seller). We don’t have too many –mongers left in Australia, but the London barrow-man, who sells fruit and vegetables, still calls himself a costermonger, but the man who supplies apples (and nothing else) to the market does not. It is likely that costermonger derives from costerd, which means apple. Costerd and custard both mean apple: the so-called custard-apple is a pleonasm.

A popular film in cinemas recently is The Imitation Game. It stars Benedict Cumberbatch as Alan Turing. If Fortune has any sense of generosity, it will fix the name of Alan Turing in the minds of millions of people who might not otherwise have heard of him.

Alan Turing was born in 1912. He was a brilliant but erratic student. He was educated at King’s College, Cambridge and at Princeton. During the Second World War he was one of the leading figures at Bletchley Park where the Germans’ Enigma Code was ultimately cracked. At Bletchley Park, Turing created the theoretical design of a programmable computing machine. As The Imitation Game illustrates, the Bletchley Park team had to use electro-mechanical devices, at a time when the most sophisticated electronic device available was the vacuum tube valve (transistors were not invented until the late 1950s; the integrated circuit was not devised until 1973).

There is a story that Turing was asked how many discrete states a computing machine would need to have. The prevailing wisdom suggested it would need 16 states. Turing thought about it overnight and came back with the answer: 2. That insight lies at the heart of the binary logic of all modern computers, which recognise just two states: one and zero; on and off.

As he wrestled with a means of encoding logical propositions in a machine, Turing recalled having read the work of George Boole (1815-1864), an English mathematician and logician. Boole had become mildly famous for a book in which he described a means of reducing logical propositions to a form of algebra. It was well-regarded in his lifetime and was soon forgotten after his death. But Turing remembered it, and used it to create the basic logic steps which lie at the heart of all computing: and, or, nand (not-and) & nor (not-or). Boole’s contribution to the area passes almost unnoticed every day, but the next time a search panel offers you a Boolean search, you will know it is a reminder of George Boole, courtesy of Alan Turing.

The received wisdom is that Turing’s work at Bletchley Park was crucial to Britain winning the war.

But Turing was gay. He had never recovered emotionally from his attachment to Christopher Morcom, a school friend he met at Sherborne, who had died in 1930. In 1952, Turing was convicted of a homosexual offence. He was not able to call in aid his extraordinary work at Bletchley Park: it was a State secret. He was offered a choice: prison, or chemical castration. He chose chemical castration, but soon regretted it. In June 1954 he committed suicide by taking cyanide. Cyanide has a very bitter taste. When his body was found, there was an apple on the bedside table. He had taken a bite out of it, apparently to dispel the taste of the cyanide.

It is widely thought that the logo of the Apple Computer is a reference to the Tree of Knowledge. That would be a fair assumption and a reasonable connection to draw. But there is an alternative which I prefer. It is thought that the Apple logo – an apple with a bite out of it – is a silent nod to Alan Turing.

I hope it is true: nothing could be more appropriate.
