Quote"Passau's city arms shows a red wolf on a silver ground - something unusual within emblems of dioceses. Because it seemed little religious to some people, the wolf was portrayed sometimes with sacral symbols such as a bishop's wand, but this never was used officially.
Since Passau was a clerical principality employing elected bishops of different houses (instead of inheritance within one family), it was difficult to agree upon one lasting city arms. The wolf is said to be bishop Wolfker's (1191-1204) emblem. Other books mention bishop Rüdiger von Radeck (1233-1250), whose family emblem showed the head of a red wolf to which the city arms is attributed.
Why and who chose the wolf as Passau's heraldic animal, is still unclear today.
Historic dates on the emblem:
1259, Jan. 29 Bishop Otto von Lonsdorf starts to use a seal showing a wolf. The end of the document says:
Et notandum, quod hec est prima littera, ubi in sigillo a tergo secretum nostrum imprimi fecimus. Quod lupum in scuto pro signo insculptum continet et superscriptionem continet SECRETVM CELA.
(… and it is to take notice that this is the first document in which we impress our secrecay seal into the seal on the back. It shows a wolf in the shield and says "Keep the secret!")
