After seeing the Francis Bacon: Man and Beast exhibition, I was impressed by two things in his paintings.
The second is the distinctive spatial structure of the lines he has added to the painting. This may be related to his early career as an interior designer. In terms of brushwork, there are even some structural lines that were added last. The purpose of these lines may not only be for corrective space, but in many cases, from his upbringing, a kind of cryptic reference to the cage, the restraint.
I tried the part of the painting by Head I with the structural line in the upper right corner. As you can see, with the addition of the structural lines, the space in the background changes from the original boundless darkness to a limited, narrow, shadowy space. This also fits better with the atmosphere that Bacon is trying to convey.
In the painting ‘Fury’, the presence of structural lines gives the impression of a roof over the space. But it is also the illogical lines that make the overall space confusing and contradictory.
I really like this use of lines to express space. In modern architecture it is often the case that frames are used with transparent materials and the sense of space is expressed simply through the lines.
In a way, this is also an expression of less is more.
