In addition to managing the flow of people in the spaces of the museum in order to maximize freedom of movement and choice, Irwin also modified the industrial window grids to create perceptual ambiguity, placing transparent glass in the inner four panes while using frosted glass for the outer panes. With this, Irwin solved the problem of either having the windows become a wall of glaring light, if all transparent glass was used, or having them become a claustrophobic muffling of space, if all frosted glass was used. Irwin's windows catch the eye in a back and forth oscillation between distant and proximal focus.
It is unusual to find such mismatched elements on a single facade as this fine stonework coexisting with these stained and rotting shutters, on a house in the fortified town of Feltre, in the northern Italian province of Belluno.
Where considerable labour lies behind the cutting and fitting of the stone, the timber planks have been left in their raw state, with no paint or carved decoration. Even the iron hinges are of the plainest variety.
Take the use of enormous plate windows...they deprive our buildings of intimacy, the effect of shadow and atmosphere. Architects all over the world have been mistaken in the proportions which they have assigned to large plate windows or spaces opening to the outside. We have lost our sense of intimate life, and have become forced to live public lives, essentially away from home.
Ruskin's Seven Lamps of Architecture provided seven guides, or 'lamps', for the troubled craftsman, guides for anyone who works directly on material things. These seven are:
The lamp of sacrifice: The willingness to do something well for its own sake.
The lamp of truth: The truth that 'breaks and rents continually'; Ruskin's embrace of difficulty, resistance, and ambiguity.
The lamp of power: Tempered power, guided standards other than blind will.
The lamp of beauty: Which for Ruskin is found more in the detail, the ornament—hand-sized beauty—than in the large design.
The lamp of life: Life equating with struggle and energy, death with deadly perfection.
The lamp of memory: The guidance provided by the time before machinery ruled.
The lamp of obedience: Obedience to the example set by a master's practice rather than by his particular works; otherwise put, strive to be like Stradivari but do not seek to copy his particular violins.
