Â­The oceans are huge. About 70 percent of the planet is covered in ocean, and the average depth of the ocean is several thousand feet (about 1,000 meters). Ninety-eight percent of the water on the planet is in the oceans, and therefore is unusable for drinking because of the salt. About 2 percent of the planet's water is fresh, but 1.6 percent of the planet's water is locked up in the polar ice caps and glaciers. Another 0.36 percent is found underground in aquifers and wells. Only about 0.036 percent of the planet's total water supply is found in lakes and rivers.
Venus on the half-shell. Sandro Boticelli, âThe Birth of Venusâ c. 1485-86, 9 ft 2 in by 5 ft 9 in. Uffizi Gallery, Florence. You may already be somewhat familiar with Boticelliâs painting âThe Birth of Venus.â The image of Venus in this painting has been used in so many ways, from advertising to satire, that it has almost become a joke.
Early Works. Titian trained under two other seminal Venetian artists, Giovanni Bellini (active by 1459, died 1516) and Giorgione (ca. 1477/81510). The latter, with whom Titian also collaborated, was influential for his tonal approach to painting and for his landscape style, which was atmospheric and evocative.itian derived the subject matter from literary descriptions of classical works of art. Venus, the mythological goddess of love, is the protagonist of a number of works by Titian, the best known probably being the so-called Venus of Urbino (Florence, Galleria degli Uffizi).
