While you are there, you might be interested in this picture John recently posted of a broad stole from the sacristy of Ss. Trinita.
The broad stole (stola latior) was used during pentential seasons by the deacon, along with the folded chasuble (planetae plicatae) for both the deacon and subdeacon -- as opposed to the dalmatic and tunicle. In fact, originally the broad stole was the folded chasuble, folded one more time and twisted.
Many may not be as readily familiar with these today, though they only ceased being used in the early 1960's. For more information about these, you may wish to consult my post on them and their history from September 10th, 2008.
