Nostredame practises during the 1546–47 plague outbreaks at Aix and Lyon as later lives tell it

Dated 1 January 1546: Nostredame practises during the 1546–47 plague outbreaks at Aix and Lyon as later lives tell it. In the causal graph this event strengthens Health-System Capacity, a driver that strengthens Hospital beds (per 1,000 people) — an improving welfare path.

Context

Presence in an outbreak is not a cure certificate. Bloodletting and aromatic powders described in the later Traité are other rows if printed. Shared work with unnamed local practitioners remains.

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

Britannica places innovative medical treatments during plague at Aix and Lyon in 1546–47 after a 1544 move to Salon. Later medical history does not convert rose-pills or bleeding into a verified mortality series. He did not file a modern epidemic return.

What the sources establish

Britannica records that after moving to Salon he gained renown for treatments during plague outbreaks at Aix and Lyon in 1546–47. National Geographic independently frames him as a physician-apothecary in plague years.

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