In particular, its first use is documented in the Vulgate, the fifth-century Latin version of the Bible,translated from the Ancient Greek by Jerome (347–420) on commission of Pope Damasus. The original meaning of the term “lunaticus” is not related only to insanity. There is also a scientific publication titled The disease of the moon: the linguistic and pathological evolution of the English term "lunatic" from that the origin of the word is related to epilepsy: The paroxysmal nature of the disease was thought to be dependent upon the phases of the moon. This appears in the Vulgate (405) of the Dalmatian Christian writer Saint Jerome (Eusebius Hieronymus, 348–420) as an epithet for “a moon-struck” person, whence “crazed, insane, lunatic.” It was used of epilepsy, from the notion that the seizures were precipitated by moonlight.

I found a list of words that ends with "-tic", but I can't find anything in common. "Lunar" and "Lunatic" seem to have evolved in a different way. "be epileptic," from selene "moon."
