They were accordingly able to fix in advance the approximate positions of these objects with reference to ecliptical stars which served as fiducial points for their determination.
They exhibit in an exaggerated form the irregularities of distribution visible in our zodiacal constellations, and present the further anomaly of being frequently reckoned as twenty-eight in number, while the ecliptical arcs they characterize are invariably twenty-seven.
The modern nakshatras are twenty-seven equal ecliptical divisions, the origin of which shifts, like that of the solar signs, with the vernal equinox.
12 The essential difference, however, between the nakshatras and the sieu is that the latter were equatorial, not ecliptical, divisions.
Are between insignificant and, for the purposes of ecliptical division, inconveniently situated objects.
