“Latin ovum meant 'egg.' The shape of an egg became a geometric category — the curve that is almost a circle but refuses to close symmetrically.”
Latin ovum meant 'egg,' from Proto-Indo-European *h₂ōwyóm. The diminutive ovalis — 'egg-shaped' — described anything that resembled the cross-section of an egg: elongated, curved, wider at one end than the other. The Romans had no separate geometric term for the shape. They simply saw it as what an egg looks like when you slice it lengthwise.
Medieval Latin scholars used ovalis in mathematics and architecture. The oval became a formal shape — not quite an ellipse (which has a precise mathematical definition) but a more general egg-like curve. The distinction mattered: an ellipse has two axes of symmetry; a true oval (egg-shaped) has only one. The egg is lopsided, and that lopsidedness is its identity.
English borrowed oval in the 1570s, and the word became standard for the shape. Cricket grounds in England and Australia are called ovals. The President of the United States works in the Oval Office (designed in 1909 by Nathan Wyeth, its shape chosen to echo the reception rooms of George Washington's Philadelphia residence). The egg shape governs sport and politics alike.
In biology, the egg that gave oval its name remains the most important oval in nature. From insect eggs to dinosaur eggs to human ova, the egg shape is functionally optimal: it resists pressure from outside, distributes weight from inside, and rolls in a circle rather than a straight line (keeping it near the nest). The Latin word for 'egg' named a shape that evolution had already perfected.

The oval is the shape that almost makes a circle and then decides not to. It is asymmetry with grace — one end wider, one end narrower, the whole thing balanced without being equal. The egg taught geometry this shape, and geometry has been using it ever since.
"The creation of something new is not accomplished by the intellect but by the play instinct acting from inner necessity." — Carl Jung. The egg is that creation: a new form, a play on the circle, and the container from which all further forms emerge.
