The fifth window is dedicated to Daniel, one of the best known prophets in the Old Testament. The Book of Daniel was written at the time of King Antiochus IV of Syria who instigated a persecution against the Jews in the Second Century B.C., that is around 162 B.C.
Daniel lives in Babylon as a young Jewish captive of King Belshazzar. One day at a banquet, fingers of a human hand appear and write on the plaster of the wall of the royal palace. The words are: “MENE, MENE, TEKEL, PARSIN.” Nobody is able to interpret the words with the exception of Daniel. In essence the words say that the rule of King Belshazzar has come to an end, a prophecy which is promptly confirmed when the king is killed that very night.
As a result, Daniel becomes famous at the court. When another king comes to power, an edict is being proclaimed announcing that all persons must pray to the ruler. Daniel only will pray to God and as a result is thrown in the Lion’s den. Miraculously an angel shuts the mouths of the hungry beasts and Daniel is saved. Hence the insertion of a lion’s head in the window.
The ram on the bottom refers to the second vision Daniel saw. The two-horned ram represents the Medo-Persian empire which eventually will be stopped and overthrown by a male goat from the west which symbolizes Alexander the Great from Greece.
