Since its existence became widely known, the codex has been studied by many scholars and amateurs, but none has succeeded in providing a widely accepted convincing translation or interpretation of the text. It was studied by the Hungarian scholar Ferenc Toldy around 1840, and later by Pál Hunfalvy and by the Austrian paleography expert Albert Mahl. Josef Jireček and his son, Konstantin Josef Jireček, both university professors in Prague, studied 32 pages of the codex in 1884–1885. In 1885 the codex was sent to Bernhard Jülg, a professor at Innsbruck University. Mihály Munkácsy, the celebrated Hungarian painter, took the codex with him to Paris in the years 1890–1892 to study it.
