 Serpens is one of the 48 ancient constellations described by Ptolemy. It is unique among the constellations in having two parts that are unconnected Serpens Caput (the head of the serpent), and Serpens Cauda (the tail) but are separated by Ophiuchus, the serpent holder. The Bayer designations of the two sections are based on the single constellation of antiquity, but their current separation means that constellations bordering one part are different from those bordering the other part:
