A primary source is anything that provides first-hand evidence. In the context of art history, primary sources are written documents from the time period that you're studying.
In addition to written documents, another source of first-hand evidence is the artworks themselves (or images of artworks). However, when art historians talk about "primary sources," they're usually referring to written documents, not to images. It's assumed that you will consult high-quality images of the artworks you're studying.
Below are three strategies for finding primary sources for Romanesque or Gothic art.
Most of the books in the library's collection are secondary sources, but some of our books are collections of primary sources. Here's an example of a collection of primary sources about Gothic art.

In particular, whenever you're examining a book, be sure to check the table of contents to see whether the book includes any primary source documents.
One nice thing about studying Medieval art is that all of the primary sources are old enough to be out of copyright. This means that they are often freely available on the Internet. Therefore, once you discover that a particular primary source document exists, you may be able to find the full text simply by Googling the title of the document.
To discover which primary source documents exist, read through secondary sources and see which primary sources they mention.
Even if you don't have a particular document in mind, there are plenty of places on the Internet where you can browse collections of Medieval documents. Here are a few to get you started:
