masc. proper name, most famously in classical history king of Macedon, father of Alexander the Great (compare philippic); the from Latin Philippus, from Greek Philippos "fond of horses," from philos "beloved, loving" (see philo-) + hippos "horse" (from PIE root *ekwo- "horse"). Skelton made it the name applied to a common sparrow (perhaps from resemblance to the bird's call). In 16c., Philip and Cheyney was a way to say "any two common men."
You remember the story of the poor woman who importuned King Philip of Macedon to grant her justice, which Philip refused : the woman exclaimed, "I appeal" : the king, astonished, asked to whom she appealed : the woman replied, "From Philip drunk to Philip sober." [Emerson, "New England Reformers," 1844]
