Canvas has become the most common assistance medium for oil painting, changing wood panels. Among the earliest surviving oils on canvas is a French Madonna with angels from around 1410 in the Gemäldegalerie, Berlin. Nevertheless, panel painting stayed more common until the 16th century in Italy and the 17th century in Northern Europe. Mantegna and Venetian artists were among those leading the modification; Venetian sail canvas was readily offered and considered the best quality.
One of Poland’s largest canvas paintings, the Fight of Grunwald by Jan Matejko (426 cm × 987 cm (168 in × 389 in)), showed in the National Museum in Warsaw.  Canvas is typically stretched throughout a wooden frame called a stretcher and might be covered with gesso before it is to be used; this is to prevent oil paint from entering direct contact with the canvas fibers, which will eventually cause the canvas to decay. A traditional and flexible chalk gesso is composed of lead carbonate and linseed oil, applied over a bunny skin glue ground; a variation utilizing titanium white pigment and calcium carbonate is rather brittle and prone to cracking. As lead-based paint is dangerous, care needs to be taken in utilizing it. Different alternative and more flexible canvas guides are commercially readily available, the most popular being a synthetic latex paint made up of titanium dioxide and calcium carbonate, bound with a thermo-plastic emulsion. Many artists have actually painted onto unprimed canvas, such as Jackson Pollock,  Kenneth Noland, Francis Bacon, Helen Frankenthaler, Dan Christensen, Larry Zox, Ronnie Landfield, Color Field painters, Lyrical Abstractionists and others.
Early canvas was made of linen, a sturdy brownish fabric of significant strength. Linen is especially appropriate for the use of oil paint. In the early 20th century, cotton canvas, often described as “cotton duck,” entered use. Linen is made up of greater quality material, and stays popular with numerous professional artists, especially those who deal with oil paint. Cotton duck, which stretches more fully and has an even, mechanical weave, provides a more affordable alternative. The arrival of acrylic paint has actually greatly increased the appeal and usage of cotton duck canvas. Linen and cotton originate from two entirely various plants, the flax plant and the cotton plant, respectively.
