The Skeireins (Gothic 𐍃𐌺𐌴𐌹𐍂𐌴𐌹𐌽𐍃) is the longest and most important monument of the Gothic language after Ulfilas' version of the Bible. It consists of eight fragments of a commentary on the Gospel of John which is commonly held to have originally extended over seventy-eight parchment leaves. It owes its title to the 19th-century German scholar Hans Ferdinand Massmann , who was the first to issue a comprehensive and correct edition of it: "Skeireins" means "explanation" in Gothic.
