- A continent is any of several large geographical regions. Continents are generally identified by convention rather than any strict criteria. A continent could be a single landmass or a part of a very large landmass, as in the case of Asia or Europe. Due to this, the number of continents varies; up to seven or as few as four geographical regions are commonly regarded as continents. Most English-speaking countries recognize seven regions as continents. In order from largest to smallest in area, these seven regions are Asia, Africa, North America, South America, Antarctica, Europe, and Australia. Different variations with fewer continents merge some of these regions; examples of this are merging North America and South America into America, Asia and Europe into Eurasia, and Africa, Asia, and Europe into Afro-Eurasia.
- Star Tales - Sagitta (ianridpath.com)
Sagitta, the third-smallest constellation in the sky, has no stars brighter than fourth magnitude, but it was well-known to the Greeks and was among the 48 constellations listed by Ptolemy in the Almagest. Aratus described it as ‘alone, without a bow’ since there is no sign of the archer who might have shot it.
