Professor[2] Arsenius Jigger was a wizard and an author specialising in Potions and Defence Against the Dark Arts.

Biography[]

In his lifetime, he wrote several books in the fields of Potions and Defence Against the Dark Arts, having written: Magical Drafts and Potions,[3] Potion Opuscule,[4] and The Essential Defence Against the Dark Arts.[5]

Arsenius Jigger also contributed to Transfiguration Today in the 1920s such as the article Lycanthropy v. Werewolfry.[6] He was also, at an unknown point, a professor of Defence Against the Dark Arts at Hogwarts School of Witchcraft and Wizardry.[2] A shop in Diagon Alley, London bears the name Slug and Jiggers, and may have been founded or owned by him.

During the Calamity in the late 2010s or early 2020s, a Calamity Investigator working for the Statute of Secrecy Task Force discovered a forgotten chapter of Jigger's Magical Drafts and Potions detailing his version of the Invigoration Draught. The Calamity Investigator studied his technique, finding it unusual and difficult to master. However, they were eventually able to use it to improve the effectiveness of their own Invigoration Draught.[7]

The same Calamity Investigator later read an editorial written by Jigger regarding potion ingredient preparation, suggesting that shaving fine slivers of newt spleen instead of chopping them helped to blend them more easily. Although the investigator believed they would never be able to fully remove the scent of spleen from their hands, using Jigger's methods did reduce the brewing time for their Wit-Sharpening Potion. The same Calamity Investigator also re-read their personal copy of Jigger's Magical Drafts and Potions and discovered that they had overlooked one of his passages on potion skimming, a technique which removed the frothy film from the surface of a potion, allowing for more consistent heating throughout the potion. The investigator utilised this technique to reduce the brewing time for all potions that they brewed.[7]

Etymology[]

  • Arsenius may be derived from the word "arsenious" meaning "containing arsenic", a very poisonous metallic element. Arsenius may also be be a reference to the famous physicist and chemist Svante Arrhenius, most widely known for formulating the first modern definition of acids and bases in molecular terms.
  • A jigger can refer to a liquid measurement that is used often for liquor, or a measuring cup specifically for measuring that amount of liquid. In the United States of America, a jigger usually holds 1.5 fluid ounces (44 ml).[8] In modern bartending, a jigger is 50 ml.
