Piero (9) Piero della Francesca (1415/17-1492)

The picture has something of this: chalk out, blueprint, equipment, line, industry, business, wire, technology, architecture, disjunct, power, sketch, expression, vector, sketchy, outline, construction, steel.
Perhaps it’s diagram of the planes of shadow in the portico in peru’s region by thomas w carnaroski, from a book of architecture.
