Vitruvius the Elemental Metallurgist is a little-known legend throughout Gielinor. In the early Fifth Age of RuneScape he authored many books on the subject of metallurgy and applying magic to metal-work, most of which have since become scattered across the lands and few remain in good condition. Vitruvius is best known for creating the Elemental Workshop, as well as the creation of the Elemental, the Mind Elemental, Body Elemental, Cosmic Elemental and Chaos Elemental equipment. Despite his well-documented life, Vitruvius is an often-forgotten historian, though he is probably one of the greatest Metallurgists in Gielinor's history.
Many of his experiments did go wrong, however; and according to legend, one of Vitruvius's apprentices, whose name is not recorded (in one of Vitruvius' books he was referred to as simply as "Idiot"), was killed during an accident while experimenting with primed elemental bars, and, later on in his studies, Vitruvius attempted to reanimate his dead assistant with the use of Body Magic. Though he was unsuccessful in that attempt he succeeded in the reanimation by transferring the mind into a body of Cosmic metal. Vitruvius later experimented with Chaos magic and created Chaos elemental metal with his assistant and an automaton he had built, named Da-vi.
- In real life, Vitruvius was a well known Roman engineer who wrote De Architectura ("About Architecture"), which is exactly what it says on the tin: a book detailing all kinds of Roman engineering practices.
- The book states that Vitruvius designed Da-vi based on a drawing made by an "old artist friend" of his, and then named it after them. The 'artist friend' he refers to is likely Da Vinci, who is the RuneScape counterpart of the real life artist and inventor Leonardo da Vinci. The drawing likely refers to the Vitruvian Man, which was drawn based on the writings of the real-life Vitruvius.
