Why is there a goat in the crest of Lublin?

There is a legend connected to the city's emblem:

In 1317 the townspeople of Lublin visited Prince Władysław the Short (pl: Łokietek) to ask him to grant them civic rights. As the prince agreed, a decision on the city's emblem was to be made. The delegation told the prince about hard times of Lublin when its townspeople had fed on goats' milk. The prince considered a goat a good symbol. However, in order not to evoke unhappy memories, he ordered them to put in the emblem something that would be associated with joy, namely a grapevine.

The oldest extisting seal of Lublin displays a hairy goat with long horns. Over the years the crest has undergone a couple of changes, a grapevine and grass were added. During the period of Partitions the city's emblem was out of use; it was reintroduced in 1918. The last change in the emblem was introduced in 2004 - the emblem is three-coloured and the colours correspond with the ones on the flag.
