Hello. You did not show the sample to which the question is referring, which makes it impossible for that question to be answered, however, I can help you by showing elements of these three types of art, which will help you to analyze your sample.
Medieval art is that which was produced in the Middle Ages, when the Catholic Church had a strong power and influence throughout Europe. The art of that period reflected this a lot and had very strong religious elements, being a sacred art. It also featured many architectural works inspired by the architecture of the Roman empire and Gothic elements, mainly in England, Germany, Italy, Poland and the Iberian Peninsula.
Renaissance art separated from the influence of the church and had less sacred elements, but invested in elements that represented the greatest expectations and desires of men. At that time, art became something more cultured and intellectual and that is why it began to exalt the human figure by placing it as the center of the universe.
Baroque art, in turn, also has many religious elements, but more dramatic and detailed than in medieval art. Here the artists preferred the use of curves over geometric shapes, they had the divine as the center of the universe and imposed a strong play of shadow and light in their works.
In the past, literacy was not very high which was why artistic forms such as paintings or pictures, and musical compositions were very much used. Another reason would most likely be how each culture has an ideal view of what beauty is and they usually work around this. This is why some cultures have a shared approach when it comes to art and cultures then can be differentiated based on the type of Art that they used.
