C.N., Pausanias
Context: During the Persian Wars, Spartan Pausanias, commander of Greek forces against the Persians, has returned some Persian P.O.W.s, kinsmen of Xerxes, to the Persian ruler, along with a letter in which Pausanias promises to enter into an alliance with Xerxes, for the purpose of reducing all of Greece to Persian control.
Text:
rex [Xerxes] tot hominum salute tam sibi necessariorum magno opere gavisus confestim cum epistula Artabazum ad Pausaniam mittit in qua eum collaudat ac petit, ne cui rei parcat ad ea efficienda, quae polliceretur: si perfecerit, nullius rei a se repulsam laturum.
Translation: The king delighted by the safe return of so many men members of his own family, quickly sent Artabazum [ his officer] to Pausanias along with a letter praising Pausanias and asking him to spare nothing in carrying out what he promised. When Pausanias has accomplished all this, Xerxes [? promised to deny him nothing.?]
I can’t quite fit magno opere into its sentence.
I can’t make out nullius rei a se repulsam laturum I feel pretty sure it is a promise of big reward, but I can’t crank the meaning out of those words. Neither can I make out the how repulsam relates to laturum, with respect to sequence of tense.
Finally, the antecedent of se is Xerxes, right? This is a summary of a letter of Xerxes, in indirect discourse.
