[150] By the apparent motion of the planetary system. [151] In reference to this passage, Placidus, in speaking of the death of Octavian Vestrius of Rome, has these words: “the Moon is found in a parallel declination of Mars, and Saturn with the opposition of Mars; the sextile of Jupiter to the Sun could give no assistance, because Jupiter is cadent, and the ray sextile is very weak, especially when it is the principal ray: for which reason, Ptolemy, in the chapter of Life, when he mentions the planets that are able to save in the courses of the infortunes, does not name the sextile, but the quartile, trine, and opposition; because the sextile ray is feeble, particularly when it is less than 60°: neither could Venus assist, as she was cadent from the house, and in a sign inimical to the Sun,” &c.
