Why it matters

Quesnay trained and made his first reputation as surgeon in ordinary to Louis XV, doctor of medicine from 1744, and later to Madame de Pompadour — well before he became the founder of the Physiocratic school of economics. This 1749 treatise on suppuration therefore sits at an unusual intersection: a working document of pre-germ-theory surgical practice written by the man read today as an economist. Physiocracy was the first systematic school of economic thought — Quesnay and his circle argued that a nation's real wealth came from agricultural land, not from gold, trade balances, or royal monopolies, directly challenging the mercantilist orthodoxy of the day. His 1758 Tableau économique attempted a single diagram tracing how income actually circulated through a whole economy, moving from landowners to farmers to merchants and back again. It's often cited as one of the earliest attempts at what we'd now call macroeconomic modeling. Adam Smith met him in Paris a few years before writing The Wealth of Nations, and it's often recounted — though not fully verifiable — that Smith meant to dedicate the book to Quesnay, had Quesnay not died before it was published.

Why we're looking

At $64 (EUR 55) this sits far below the one specialist comp we found — Librairie Alain Brieux's 1749 first edition in contemporary marbled basane, condition 'Bon', at US$459.64 — though it is roughly in line with the cheaper end of the French-dealer copies visible on AbeBooks (about EUR 55–75), so the gap to the specialist ask is the interesting figure rather than a clear market-wide bargain. The seller's own note of a fragile front board plausibly accounts for part of the spread.

Watch out for

The item specifics contradict themselves — 1749 as publication date but 'Époque: XIXème' — which is most likely a dropdown mis-selection but should be settled by asking for a title-page photograph, especially since later d'Houry printings (Veuve d'Houry, 1764 and 1770) exist and are easily conflated with the 1749 sheets. Condition is barely described: 'fragility of the front board, clean interior' tells you nothing about the spine, hinges, or completeness, and comparable dealer copies are collated at [12]-432 pp., so ask the seller to confirm the text runs complete to p. 432. The seller's feedback record is strong on description accuracy, but that is a track record, not a collation.
