Am. 450, Jove’s four-in-hand if you should mount, and try to flee from here, even so you’ll scarce escape a dreadful doom. sīquidem summum Iovem tē dīcās dētinuisse, malam rem effugiēs numquam, Pl. As. 414, e’en shouldst thou say imperial Jove detained thee, chastisement thou’lt ne’er avoid. sī frāctus inlābātur orbis, inpavidum ferient ruīnae, H. 3, 3, 7, should heaven’s vault crumbling fall, him all undaunted will its ruin strike. neque tū hoc dīcere audēbis, nec sī cupiās, licēbit, V. 2, 167, you will not dare to say this, sir, nor if you wish, will you be allowed.
