Contributed by David Carrier / Alessandro Twombly’s twelve large new paintings, now on view at Amanita Gallery, all employ one basic, immensely fruitful motif: knots of color resembling enlarged floral forms, depicted in high-pitched, gesturally painted oranges, pinks, reds, and blacks on bright turquoise backgrounds. An artist friend nicknamed these pictures ‘Tiepolo in the Sky,” which accurately describes them. Twombly’s abstract images look like drastically enlarged figures you might find in a work by the eighteenth-century Italian painter Giovanni Battista Tiepolo. They are strikingly original yet richly allusive.
