Work is something that we all must do — we spend our lives acquiring a trade and skill. We study, practice, and hone our skills throughout our lives. The books, the workshop, the compass, the window, and the knot are all symbols that represent the life and work of the craftsman.
During the renaissance, Leonardo DaVinci created a symbol of intricate knotwork as a logo — or unique identifier — for a studio of craftsmen. The intricate lacing of the know, the precision of the geometry, and the endless line all represent the nature of work, quality, and attention to detail.
