Jan Očko of Vlašim

His coat of arms was that of bishop and silver two Vulture heads gules (common with of Vlašim and Jenštejn).

In 1366 he ordered the incarceration of Jan Milíč z Kroměříže for his preachings against Charles IV, whom he called the "Antichrist".

[dubious – discuss] Jan Milíč was later freed by Charles and remained in his favour.

On 18 September 1378, by nomination of Pope Urban VI, he became the first Bohemian named a Cardinal.

[citation needed] According to Konrad Eubel,[1] Joannes de Jenzenstein was appointed to succeed him on 19 March 1379.
