According to texts, very much so.  Here is an excerpt from a song written by Caliph Harun al-Rashid’s brother, Ibrahim, about the vizer:

To find words for his beauty, think of the purest gold coin of ancient Egypt;

The pearl, which, glowing from the shell’s depths, breaks the diver’s heart;

Or gold leaf floating from the craftsman’s hand to guild the pages of a wondrous book.
