research
Then, how to analyse an artwork using of appropriate research:
1) Gather data on the author (such as date of birth and death, social origin, training, other works);
2) Recognise the subject (religious scene, historical, mythological, allegorical, portrait, landscape, etc.; if it is part of an exhibit, and what was its first public appearance, etc.);
3) Analyse the subject (i.e.: a description of what is represented, settings, frames, characters, actions, etc.).
If it’s the case, we can also add data relating to its location, creating a brief caption: author, title, date of production, support/material, dimensions, and place of storage/display.
When we describe a work of art, we must start by writing our first impressions. These may help us further on in our analysis. However, bear in mind that we must always justify our findings so that others can relate to them and thus understand them.
We can, for example, establish comparisons between several works or even between artists and consider alternatives that could have been chosen by the artists. We may even meditate on what might have affected the artist’s choices in this or that particular work.
meanings
Finally, we must conclude with an analysis of meanings (real or symbolic) of the piece in question.
We should base this analysis on our research, on the symbols and iconography present in the work of art and, eventually, on the comparison with works by the same author and period.
Remember: anything that is actually observable in the work of art is noteworthy and reason for analysis.
