If, like me, you yawn all morning, try slyly to snooze all afternoon, start to feel tolerable in the evening, but don't truly wake up until you hear the chimes at midnight, you are a lychnobite. This comes from the Greek lokno-bios, which literally means lamp-life. For your life is lived in the shadow of the earth.
Lychnobite was invented by Seneca to describe noctivagant souls like me. It was then invited into English by Nathan Bailey in his Universal Etymological Dictionary of 1727. He defined lychnobite as 'a night walker', but the meaning has now spread to night shift workers and sleepless fishermen.
When, in the small and wee hours, I find myself with nothing to do, I settle down and knock off couple of posts for Inky Fool. I lucubrate. I produce lucubrations.
To lucubrate is to work by artificial light, from the Latin lucubrare. As I have usually had a few drinks by that time, what you end up reading are the lubricated lucubrations of a lychnobite.
Incidentally, the small hours are just as long as the other ones. I've checked. It is the o'clocks - one, two, three - that are small.
