Zibeline (in German "Zobelfell", in Czech "sobol", and in Hungarian "coboly") was already used in the ancient times of heraldry. Some minnesängers applied the word "Zobelfell" for the black tincture, and the arms of the count von Zollern also contained zibeline ("Zobelfell"). The colour and hatching of marten (in German "Marderfell", in Czech "kunina", and in Hungarian "nyest") is identical with the red (gules) tincture. The origin of the word gules is from the Medieval Latin word "gula", which means the mouth of a carnivorous animal, and in some cases the goules are made of the marten fur (one text says goules de martre). Maybe its reddish tint came to the heraldry from the fur of pine marten. In the poem of Konrad von Würzburg we can read "kelen rôt" (line 985) transformed into modern German as "pelzrot". (Furthermore, we can read there phrases like "vîz hermelin" (405), which is "hermelinweiß", and "zobel" (400) as well.) Though the Webster's Dictionary defines the meaning of "pine" as a white, yellowish timber and the Cambridge International Dictionary defines it as a timber usually pale in colour, no source, including heraldry textbooks, mentions it in connection with heraldry.
