Brevis esse laboro, obscurus fio; sectantem levia. Nervi deficiunt animique. (Latin proverb)
Translation: "When I try to be brief, I become obscure. Aiming at smoothness, I fail in force and fire."

From Ars Poetica, by Quintus Horatius Flaccus (Horace) who was instructing writers that it may be difficult to achieve brevity without sacrificing clarity.

Not that the story need be long, but it will take a long while to make it short."

—Henry David Thoreau (1817-1862) U.S. naturalist and author
Caesarean [Cesarean] section.
Incision through the abdominal and uterine walls for delivery of a fetus.

Also known as "an abdominal delivery". There are claims that Gaius Julius Caesar was delivered by such an operation, but evidence disputes such a claim. Fact: the first known successful Caesarean section was recorded in Pavia, Italy, April, 1876, from a Julie Covallini. Fact: although the operation was occasionally used in ancient times, the Caesarean section usually resulted in death for both the child and the mother. There were some occasions when the child survived, but the mother inevitably perished.

Caesar's mother, Aurelia, lived to be at least seventy years old and was apparently in good health up until the time of her death. This would suggest that she never had such a deadly operation.

cosecant
cutisector
An instrument used to remove a section of skin for microscopic examination.
