[3], Titian follows Ovid fairly closely, although it is likely that his Latin was poor, and he mainly relied on somewhat simplified versions in Italian, of which there was a choice. Barnard. The painting is well-travelled; painted in Venice, it was delivered in modern Belgium, then went to Spain, Italy, England, and France before returning to England. [18] The brightest component is a blue-white main-sequence star of spectral type B8V,[19] which is 3.5 times as massive and 180 times as luminous as the Sun. [18] These two are separated by only 0.05 astronomical units (AU)—five percent of the distance between the Earth and Sun; the main dip in brightness arises when the larger fainter companion passes in front of the hotter brighter primary. Poseidone scatenò contro il paese di Cefeo la furia delle acque e di un mostro marino.
