The first living beings were born in moisture, enclosed in a prickly bark; and as they advanced in age, they came forth on to the drier part and, when the bark had broken off, they survived for a short time.

The infinite (apeiron) is the principle and element of existing things.

The earth is a celestial body, supported by nothing, remaining in its place because of the equal distance from all parts of the circumference.

The sun is not under the earth, but around it, and is hidden from us by the higher parts of the earth, and appears again when the earth tilts.

The world is perishable and arises and passes away in an infinite succession.

The boundless (apeiron) is the divine, for it is immortal and imperishable.

All things come from the boundless and return to the boundless.

The earth is like a stone column; we walk on one of its flat surfaces.

The celestial bodies make full circles, passing also beneath the earth.

The order of the celestial bodies: after the circle of the stars, the moon, then the sun, then the other planets.

The sea is diminishing and will eventually dry up.

The first principle is not water or any other known element, but a different, boundless nature.

The boundless (apeiron) is ungenerated and indestructible.

Time orders the cycle of generation and destruction.

The earth hangs freely, not held by any chain.

The sun, moon, and stars all originate from the fiery ring that separated off from the original boundless.

Eclipses of the moon occur when the breathing-hole in the wheel is blocked.

The phases of the moon are caused by the gradual blocking and opening of its aperture.

The earth's shape is curved, round like a drum.

The boundless (apeiron) surrounds and steers all things.
