cannabis

Canvas comes from Old Northern French canevas, which derived from Medieval Latin canabacius, from Latin cannabis — the hemp plant (Cannabis sativa). The word was borrowed into Latin from Greek κάνναβις (kánnabis), itself borrowed from a Scythian or other Iranian source. Hemp fiber was among the most important industrial textiles of the ancient and medieval world. It was stronger and more durable than linen when wet, which made it invaluable for ships' sails, ropes, and maritime rigging. The heavy, coarse cloth woven from hemp was canvas — literally 'hemp cloth' — and this material's properties made it suited to many uses beyond sailing: as filters in industry, as the soles of shoes, as bags, as awnings, and eventually as a painting surface.

Painters began using canvas as a substitute for wooden panel in earnest during the fifteenth and sixteenth centuries, first in Venice where the maritime industry made hemp cloth abundantly available, and where the humid lagoon climate made wood panels warp and crack. Canvas offered distinct advantages: it was lighter, cheaper, could be rolled for transport, and could be made in larger sizes than most wooden panels without structural problems. The Venetian painter Giovanni Bellini and his successors developed the technical conventions for preparing canvas as a painting surface — sizing with animal glue, priming with gesso — and the medium spread rapidly. Titian's large-format paintings in Venice, Veronese's enormous feast scenes, Tintoretto's vast compositions all required canvas. The hemp plant that rigged the Republic of Venice's fleet also held the paint of its greatest artists.

The spread of canvas as the dominant painting support transformed the economics and geography of art. A painting on panel could not easily cross the Alps — the wood risked cracking in transit. A painting on canvas could be unrolled from its stretcher, rolled around a cylinder, and shipped across Europe. The art market of the seventeenth and eighteenth centuries was made possible, in part, by hemp cloth: works could travel from Amsterdam to Madrid, from Rome to London. The collector's ability to acquire art from distant studios depended on the portability of canvas. The hemp plant did not merely hold the paint — it made the art market mobile.

Today, 'canvas' names both the physical material and the metaphorical space of creative work. A 'blank canvas' is an opportunity, a beginning, an unformed possibility. We speak of the world as a canvas, of life as a canvas, of a company's market as a canvas on which strategy will be painted. Digital painting applications name their working surface the 'canvas,' and the dominant web drawing API is called the HTML Canvas element. The hemp plant's industrial textile has become the universal metaphor for creative surface — for the space where making becomes possible. The word has traveled from the Scythian steppe to Venice's lagoon to the internet, carrying with it the useful flatness of a woven surface stretched taut and ready to receive marks.
