Intro and Visual description

Located in the hands of Ophiuchus, Serpens is the only constellation divided into two parts: Serpens Caput (=head) and Serpens Cauda (=tail), with Ophiuchus between them.

Serpens brought Ophiuchus an herb that could revive the dead.

Serpens is included in the ancient star catalog of Ptolemy, but not in the catalogs of Eudoxos of Knidos and Aratos of Soli.
