Gazualum De lancastre, (-1247, ?) was a brick maker in Babylon.
Gazualum believed in Yazdanism.
He lived a life of poverty. He was able to eat and sleep under a shelter, but ended with having no possession at all. He was rather respected though seen as belonging to the middle class. However, he could access to many opportunities. He had a refined culture, and was known to read, and sometimes write, for pleasure. He was force of nature, and people saw in their body and beauty the incarnation of a god. He was iron-willed, achieving any goal he set.
