Have a look at these paintings of St Jerome in his study: they each contain at least one idea that I will use to create my 'headspace'. In the frescoe below I see a pleasant homely clutter of writing and study implements including scissors, books and sheafs of paper. I am particularly interested in the overhead shelf.
The painting below shows the Saint in a more contained, closet-like carrol. It is not hard to imagine this 'study' as a box-like room of sorts, or at least an alcove. This painting is a delight, with the Saint's attendant lion stretching its paw up towards his hand. Again with the pleasing clutter of the man of letters.
This painting introduces a spatial relationship of particular interest: the study or carrol as a timber element you climb onto, in the corner of a larger room, positioned beneath a window. Again with the clutter.
The final painting elaborates the theme: platform of timber, corner of the room, positioned with a window integrated into the joinery. The Dutch style of side lighting is also important.
So that's the inspiration. Watch this space to see where I go with it. It is shaping up to be my most eccentric project to date: good times.
