Bismuth was probably unknown to the ancients. The first time it is mentioned is in the 15th century. In 1450 Basileus Valentinus (1565-1624) referred to it by the name wismut, and characterized it as a metal; some years later Paracelsus termed it wissmat, and, in allusion to its brittle nature, affirmed it to be a "bastard" or "half-metal". The first clear description of Bismuth as a separate metal is from Georgius Agricola (1494-1555), De natura fossilium Libri X (1546) (note). Agricola described it as an "ashgrey lead", unknown to the ancient Greeks and Latins. It is a separate metal, different from lead and tin, but similar to them. It is brittle and harder than tin and lead. The density is between tin and lead. The luster of a polished surface is between that of tin and lead. Bismuth is mined at Schneeberg, Erzgebirge, Sachsen, Germany. Agricola used the form wissmuth, latinized to bisemutum, and also the term plumbum cineareum.

There exist also a document from 1477 on a Bismuth mine at Schneeberg, this means that the name was already known and was apparently not uncommon in this area. Alchemy held that one metal could be transformed to another. Miners believed there were three types of Lead: Ordinary, Tin, and Bismuth. Silver was often found in ore below Bismuth. So they believed that Bismuth had progressed farthest but not completed its transmutation to Silver. Striking a vein of Bismuth, miners would say sadly, "Alas, we have come too soon."

Edmund von Lippmann, in his book on the history of Bismuth (note), encountered in the literature from the 15th to the 17th century 21 names for the metal. In Cadet's Dictionnaire de Chimie of 1803 (note) Bismuth and some of its compounds are described in detail and given many synonym names: Demogorgon, Glaure, Nimphe, Étain de glace, and Étain gris (gray tin).

In early times Bismuth was confused with Antimony, Tin and Lead. Only in the middle of the 18th century, through the research of Claude-François Geoffroy dit Geoffroy cadet (1729-1753) (note), who described his observations in appeared in the Mémoires de l’académie française for 1753, His early death prevented further research on Bismuth. Johann Heinrich Pott (1692—1777), published in his Exercitationes chemicae de Wismutho (1769), and Torbern Olof Bergman (1735-1784) reinvestigated Bismuth's properties and determined its reactions. Bergman's account was published in his Opuscula. By the work of Bergman, Bismuth was definitely recognized as a specific metal.

Von Lippmann explains the name as derived from the German Weisse Masse = white material, which later altered to Wismuth and Bisemutum.

Often is the name Bismuth explained as a derivation from the German, from the saying that one the element "in der Wiese mute" (applied for mineral rights in the meadow). According to Thomas Witzke, the derivation of the element name from "in der Wiese muten" is unlikely. The term is difficult to translate. "Wiese" is meadow, and "muten" means an announcement to mine for special ores or metals. The owner of the mine must announce to the mining authorities the ores or metals that he wants to mine before starting his work.
An origin of the name in the Erzgebirge area, especially at Schneeberg, is very likely. All the early documents on Bismuth refer to Schneeberg. The mining at Schneeberg started between 1400 and 1450. Schneeberg was founded as a result of the Silver findings at this time. Main parts of the Erzgebirge were primeval forest, and meadows were not a characteritic features at this time in this area. Main clearings of the forests were a result of the growing population due to the mining. Bismuth was found at Schneeberg in several mines in large quantities (in difference to other mining areas in Germany!), but the need of Bismuth was rather low - a small quantity for medical use and somewhat for the types for book printing. In all the early documents, there is only one Bismuth mine mentioned. Typical announcements were for Silver, somewhat later also for Cobalt ores, but not for Bismuth. With increasing book printing, the use of Bismuth grows, but at this time the name was already known.
All in all, a derivation from "in der Wiese muten" sounds nice, but is rather unlikely. Neither meadows were characteristic for the beginning of the mining in this area, nor "muten" for Bismuth is likely or were of greater economic interest at the time of the origin of the name.

Other suggestions for the origin of the word Bismuth are

• a derivation from the Arab "bi ismid" = having the properties of Antimony [al-ithmīd] (Мир Химии and Musée de minéralogie);
• a derivation from the Greek "psimydos" = white lead (in French blanc d'argent), one of the oldest paint pigments (basic lead carbonate, a mixture of lead carbonate and lead hydroxide, (PbCO₃)₂ Pb(OH)₂). However, the word "psimydos" does not exist, the correct Greek word for white lead is ψιμυθιον (psimythion) (Musée de minéralogie in Paris);
• after the name of the German region Визен (the transliteration is Vizen, maybe Wiesen, I don't know which region is meant) (Мир Химии).
