The ' far-away light ' () is a reference to St Elmo's Fire, an electrical discharge supposed by ancient Greek mariners to be an epiphany of the Dioscuri, but the meaning of the line was obscured by gaps in the papyrus until reconstructed by a modern scholar — such reconstructions are typical of the extant poetry ( see Scholars, fragments and sources below ).

An anode is an electrode through which electric current flows into a polarized electrical device.

An analog computer is a form of computer that uses the continuously changeable aspects of physical phenomena such as electrical, mechanical, or hydraulic quantities to model the problem being solved.
