Imported art albums can be bought in some places in China. Now Zhuoyue and Azure also provide foreign book ordering services, provided that you know the nomination or author name of the book you ordered. This theme should not be new, there should be some shaped works abroad. There are also albums written on this theme in my impression, but generally speaking, due to the copyright problem of pictures, the compilation of foreign albums is not so comprehensive as an encyclopedia. Most of them are based on the collections of a museum or a national museum, and the number of themes you lock will not account for a large proportion of the paintings, and it is unlikely that all of them will be concentrated in a country or an art gallery, so the album is not easy to collect. Moreover, foreign art collections are very rich. In fact, you can see almost less than 9 hairs by looking at the picture books in China, and most of the works you are looking for on this subject may be invisible to us.
There are not many well-known western works on this subject in China, such as Van Eyck's The Wedding of the Arnold Finis, Brou Gail's The Farmer's Wedding, and the occasional virgin Mary wedding in religious works, such as Raphael's The Wedding of the Virgin Mary, are really rare. Of course, you may have a wealth of information at hand, which is the best. In addition, I would like to remind you that not all Renaissance paintings are oil paintings, and many works are painted with wooden boards and eggs, which should be carefully defined. If it is limited to oil painting, many Renaissance works will be excluded.
There is also a literature review section, which is not a new topic. There should already be some shaped works abroad, so you must exhaust the key works in this field as much as possible before making a paper (the literature review of the paper should focus on international literature, especially if you study foreign art). Let's take a look at what our predecessors said first. There is no Chinese translation of this book in China, so we can only find the original text. However, it is not easy to find these books accurately and list an authoritative catalogue. If your tutor is an expert, you'd better ask him. Otherwise, it will take a lot of time to understand the bibliography, read it, and determine the value of each book, so as to make a literature review. If you are studying now, please be patient and take your time.
In addition, if you really want to do this topic, if you still have time, I suggest visiting some museums in Europe during the summer vacation to collect first-hand information. I believe it will inspire you a lot, because the height of the thesis can only be limited to the level of long argumentative essays in middle schools, and it can't reach the level of the thesis. Generally, only the masterpieces of first-class masters can be seen in China, and these works account for only a small proportion of European art collections. And a large number of research materials with historical value actually come from a large number of works by Ersanliu or unknown painters. After all, there are too few painters whose works are represented by wedding themes. However, after17th century, many commercial paintings in northern schools will involve this theme, and many of these things are not elegant, or are not valued by album publishers. Only by going to a large number of museums in person can we get a more objective overall understanding. This is the minimum requirement for writing a thesis. At the same time, it is best to learn as many languages as possible. Most bookstores in Europe only sell books in their own languages, and English book counters only account for a small part, and there are only two or three books, which have little academic value. In Europe, English books are generally sold to tourists, not scholars. It is still necessary to buy books. There are too few valuable things to see in China, and at present, many academic works in China are far from academic compared with foreign countries. Since we study western art, we still have to read books written by westerners. Don't think that there are few people writing books abroad, and don't use the domestic situation to infer foreign countries. Every year, China's publications only account for 1% of all publications on the earth, and 90% of this 1%.
I think you have a long way to go on this topic. Practically speaking, to put it mildly, if you just want to graduate, the time cost and material cost are too high. Unless you are really interested in this issue and even want to take it as a long-term academic direction in the future, then these basic investments are very necessary now.
