each composed the same iambic line. But the alteration of a single word by Euripides, who employed the rarer term instead of the ordinary one, makes one verse appear beautiful and the other trivial. Aeschylus in his Philoctetes says: {Phi alpha gamma epsilon delta alpha iota nu alpha / delta / eta / mu omicron upsilon / sigma alpha rho kappa alpha sigma / epsilon rho theta iota epsilon iota / pi omicron delta omicron sigma}. Euripides substitutes {Theta omicron iota nu alpha tau alpha iota} 'feasts on' for {epsilon sigma theta iota epsilon iota} 'feeds on.' Again, in the line, {nu upsilon nu / delta epsilon / mu /epsilon omega nu / omicron lambda iota gamma iota gamma upsilon sigma / tau epsilon / kappa alpha iota / omicron upsilon tau iota delta alpha nu omicron sigma / kappa alpha iota / alpha epsilon iota kappa eta sigma), the difference will be felt if we substitute the common words, {nu upsilon nu / delta epsilon / mu / epsilon omega nu / mu iota kappa rho omicron sigma / tau epsilon / kappa alpha iota / alpha rho theta epsilon nu iota kappa omicron sigma / kappa alpha iota / alpha epsilon iota delta gamma sigma}. Or, if for the line, {delta iota phi rho omicron nu / alpha epsilon iota kappa epsilon lambda iota omicron nu / kappa alpha tau alpha theta epsilon iota sigma / omicron lambda iota gamma eta nu / tau epsilon / tau rho alpha pi epsilon iota sigma / omicron lambda iota gamma eta nu / tau epsilon / tau rho alpha pi epsilon zeta alpha nu,} We read, {delta iota phi rho omicron nu / mu omicron chi theta eta rho omicron nu / kappa alpha tau alpha theta epsilon iota sigma / mu iota kappa rho alpha nu / tau epsilon / tau rho alpha pi epsilon zeta alpha nu}. Or, for {eta iota omicron nu epsilon sigma / beta omicron omicron omega rho iota nu, eta iota omicron nu epsilon sigma kappa rho alpha zeta omicron upsilon rho iota nu} Again, Ariphrades ridiculed the tragedians for using phrases which no one would employ in ordinary speech: for example, {delta omega mu alpha tau omega nu / alpha pi omicron} instead of {alpha pi omicron / delta omega mu alpha tau omega nu}, {rho epsilon theta epsilon nu}, {epsilon gamma omega / delta epsilon / nu iota nu}, {Alpha chi iota lambda lambda epsilon omega sigma / pi epsilon rho iota} instead of {pi epsilon rho iota / 'Alpha chi iota lambda lambda epsilon omega sigma}, and the like. It is precisely because such phrases are not part of the current idiom that they give distinction to the style. This, however, he failed to see. It is a great matter to observe propriety in these several modes of expression, as also in compound words, strange (or rare) words, and so forth. But the greatest thing by far is to have a command of metaphor. This alone cannot be imparted by another; it is the mark of genius, for to make good metaphors implies an eye for resemblances.
