battery (n.)youdaoicibaDictYouDict
1530s, "action of battering," from Middle French batterie, from Old French baterie (12c.) "beating, thrashing, assault," from batre "beat," from Latin battuere "beat" (see batter (v.)).

Meaning shifted in Middle French from "bombardment" ("heavy blows" upon city walls or fortresses) to "unit of artillery" (a sense recorded in English from 1550s). Extension to "electrical cell" (1748, first used by Ben Franklin) is perhaps from the artillery sense via notion of "discharges" of electricity. In Middle English, bateri meant only "forged metal ware." In obsolete baseball jargon battery was the word for "pitcher and catcher" considered as a unit (1867, originally only the pitcher).
cyclops (n.)youdaoicibaDictYouDict
(plural cyclopes), 1510s, from Latin, from Greek kyklops, literally "round-eyed," from stem of kyklos (see cycle (n.)) + -ops (see eye (n.)). One of a race of one-eyed giants who forged thunderbolts for Zeus, built the walls of Mycenae, etc.
forge (v.1)youdaoicibaDictYouDict
early 14c., "to counterfeit" (a letter, document, etc.), from Old French forgier "to forge, work (metal); shape, fashion; build, construct; falsify" (12c., Modern French forger), from Latin fabricari "to frame, construct, build," from fabrica "workshop" (see forge (n.)). Meaning "to counterfeit" (a letter, document, or other writing) is from early 14c.; literal meaning "to form (something) by heating in a forge and hammering" is from late 14c. in English, also used in Middle English of the minting of coins, so that it once meant "issue good money" but came to mean "issue spurious (paper) money." Related: Forged; forging.
manacle (n.)youdaoicibaDictYouDict
mid-14c., "a fetter for the hand," from Old French manicle "manacles, handcuffs; bracelet; armor for the hands," from Latin manicula "handle," literally "little hand," diminutive of manicae "long sleeves of a tunic, gloves; armlets, gauntlets; handcuffs, manacles," from manus "hand" (see manual (adj.)). Related: Manacles.
In every cry of every man,
In every infant's cry of fear,
In every voice, in every ban,
The mind-forged manacles I hear

Prester JohnyoudaoicibaDictYouDict
c. 1300, Prestre Johan, legendary medieval Christian king and priest, said to have ruled either in the Far East or Ethiopia. From Vulgar Latin *prester, a transition between Latin presbyter and English priest. First mentioned in the West by mid-12c. chronicler Otto of Freising, who told how Johannes Presbyter won a great victory over the Persians and the Medes. Between 1165 and 1177 a forged letter purporting to be from him circulated in Europe. All this recalls the time when the Christian West was culturally backwards and militarily threatened, dreaming of a mythical deliverer. Compare Old French prestre Jehan (13c.), Italian prete Gianni.
