Glass blowers shape vases from molten material using nothing but their own controlled breath, a craft in which the maker's body, specifically the breath that also keeps a person alive, is the direct instrument of the finished, beautiful object. Saturn's decan and Venus's term combine here to favor discipline in the service of beauty, structure and grace meeting in the same craft.
Jones took the picture from Wheeler in Balboa Park in 1925; the reading attached to it here is Rudhyar's 1973 wording, and breath, in this reading, becomes a stand-in for the whole of one's living energy, spent deliberately and under control rather than released carelessly. The shadow of a craft this exacting is a breath mistimed or a moment's loss of control, since molten glass forgives very little, and the same controlled instrument that shapes the vase can just as easily ruin it. Leo's creative confidence, the sign most associated across the whole zodiac with the act of making something and wanting it seen, finds one of its clearest, most literal images in a craftsman whose product is inseparable from his own body's breath. At a natal or progressed placement the degree tends to favor crafts and callings where the maker cannot be separated from the made, and its discipline is the breath's own: steady, timed, and impossible to fake.
