Newton's Dark Secrets
Isaac Newton is well known for his mathematical and scientific achievements,
yet few people know about his work as an alchemist. Some people believe that
Newton pursued alchemy with the hopes that it might help him better understand
great truths about nature and the universe. Many alchemists described their
work in symbols and metaphors. In this activity, you will use a glossary of
alchemical symbols to interpret a passage from a famous alchemical text called
The Twelve Keys of Basil Valentine.
Read the text passage on this page. Use a pencil or highlighting pen to mark
any words or phrases you think might be clues to the text's meaning.
As a team, use the description of common symbolism for alchemical
substances, principles, and elements on the "Keys to the Stone" handout to
decipher the text. Note that some symbols and images have more than one
Together, write your interpretation of the text on a separate piece of
paper, and then share your work with the class. When interpreting the text,
refer to the line number in which the word or phrase appears.
The Twelve Keys of Basil Valentine
The Twelve Keys of Basil Valentine is a famous alchemical text that
appears to have first been published in Germany around 1599. The text was later
translated into Latin, Greek, and English. The author, "Basilius Valentinus,"
claimed to be a Benedictine monk. The author's true identity is unknown. The
text itself contains 12 coded passages, or keys, that describe the process of
creating the Philosopher's Stone, a mythical substance believed to cure
disease, confer immortality, and turn ordinary metals into gold. The following
is a part of the first step, which involves preparing the materials to be used
in the creation of the stone.

2 a fierce grey wolf, which, though on account of its
3 name it be subject to the sway of warlike Mars, is
4 by birth the offspring of ancient Saturn, and is found
5 in the valleys and mountains of the world, where he
6 roams about savage with hunger. Cast to him the
7 body of the King, and when he has devoured it, burn
8 him entirely to ashes in a great fire. By this process
9 the King will be liberated; and when it has been
10 performed thrice the Lion has overcome the wolf,
11 and will find nothing more to devour in him. Thus
12 our Body has been rendered fit for the first stage
13 of our work.

Compare your team's interpretation of the text to others in the class. Did
different teams come up with the same answer? Why or why not? Discuss and
defend your choices.
Newton used his own symbols and phrases to describe the steps he took when
performing alchemical experiments. Explain why he might have done this.
