Following the death of Jan Huss, the leadership of the Slavic religious reform movement passed to the Utraquist preacher Koranda, who supported the
controversial practice of taking communion sub utraque (under both kinds), that is in the form of both bread and wine. Here he is shown preaching to a gathering crown at Krisky on 30 September 1419, when he advised his
followers that weapons as well as faith would be needed. This was the start of the Hussite Wars, as foretold by the dark skies. The white and red flags are symbols of life and death.
