(perfect) are primary: (Caesar) 'he instructed that everyone was to attack Indutiomarus alone, and that no one is to wound anyone before he has seen Indutiomarus killed' Commenting on this sentence, Postgate suggests that the change to primary tenses represents some 'sharpening of the emphasis'. Andrewes (1937, 1951) points out that different authors have different practices in regard to the use of primary and historic tenses in indirect speech. Cicero generally follows the sequence of tenses, but this is not always true of Caesar. In some examples Caesar seems to use the present subjunctive to refer to a future time, and the imperfect to refer to the current situation. Thus in the following examples, and are in the present subjunctive because they refer to a future time: (Caesar) 'moreover, even if no one else were to follow him, he would go with the tenth legion alone, about whose loyalty he had no doubt.' (Caesar) '(the ambassadors said that) the Helvetii were intending to make a journey through the province, because they had no other route; and that they were requesting that it might be allowed for them to do so with Caesar's permission' In Livy and Tacitus, on the other hand, the tense of the reported verb tends to follow the tense of the indicative of direct speech; thus in the following example, a perfect indicative turns into a perfect subjunctive (), and an imperfect indicative into an imperfect subjunctive ():Postgate (1905), p. 442. (Livy) '(he said that) he would have made an attack the previous day in the council, but the matter had been postponed, since the convenor of the council had been absent, whom in particular he had been aiming for.' However, when the original verb in direct speech is subjunctive, these authors follow the sequence of tenses rule. In the following sentence of Tacitus, the present subjunctive represents a present indicative, but the imperfects and , following the historic introductory verb, represent present subjunctives in direct speech: (Tacitus) 'but now that he was not being induced by fear, he would go so that he could look at the situation and make a settlement.' The use of primary and historic subjunctives in this example from Tacitus differs from the preceding examples from Caesar, since in Tacitus the present subjunctive refers to the current situation, and the imperfect to future time. However, Caesar is not always consistent, and Postgate
