Read the full account

From 1667–68 Leibniz entered the service of Mainz under Johann Christian von Boineburg, writing legal and diplomatic papers including Egyptian-plan diplomacy toward France. It is not the Paris mathematical years as a second twin.

Context

SEP and Britannica independently print the Mainz years. A counsellor of electors is not a representative office.

Gottfried Wilhelm Leibniz’s documented role is bounded by other offices and collaborators named in the sources below.

Conventional years are 1646–1716. Surviving public files are GWLB Nachlass pages, the Akademie-Ausgabe, SEP, and encyclopedias. Leibniz did not typeset those later pages. Later electronic computers are not this life.

Why it matters

Resilience-harm path via princely employment. High confidence on the posting.

Who was responsible

Contribution type and responsibility level for each recorded actor — not sole-author shorthand.

What the sources establish

Britannica and SEP independently describe the Mainz–Boineburg service.

Established: Mainz service from the late 1660s. Not established: that any one Egyptian memorial moved Louis XIV’s policy by a unique coefficient.

Gottfried Wilhelm Leibniz did not file a later UNESCO form, a later Loeb colophon, or a later museum label as a personal act.
