Briefing

Do Not Disturb My Circles

Syracuse, Sicily, 212 BC. After a siege of two years, Roman soldiers are pouring into the city. In a quiet courtyard an old man sits drawing circles in the dust, so lost in his problem that he has not noticed. He is Archimedes, the greatest mathematician of the ancient world, the man who worked out how close 22/7 comes to the number we call pi.

The Roman general Marcellus has ordered that Archimedes must not be harmed. But the soldier now coming through the gate does not know who the old man is. Seven puzzles stand between you and the end of the story. Solve them all, and one last word tells you how it ended.

TACUIT

Tacuit — he fell silent. According to the story, Archimedes' last words to the soldier were “Do not disturb my circles!” Marcellus was grief-stricken, gave him an honourable burial and looked after his family.
