"Detail of a scene in the bowl of the letter 'P' with a woman with a setsquare
and dividers; using a compass to measure distances on a diagram. In her left hand she
holds a square, an implement for testing or drawing right angles. She is watched by a
group of students. In the Middle Ages, it is unusual to see women represented as teachers,
in particular when the students appear to be monks. She may be the personification of
Geometry. Illustration at the beginning of Euclid's Elementa, in the translation
attributed to Adelard of Bath."

DRAW THE LINE
they say LOVE makes the world go round
only a square would disagree
love triangles are sometimes found
in life's complex geometry
all sorts of angles may abound
there's no obvious Q.E.D.
