Vocabulary Challenge: O prophetae!

Here's the vocabulary challenge for May 26:

O (exclam.) - ante (prep. + acc.) - via (viae) - sine (prep. + abl.) - praedico (praedicere)

Here's the sentence I came up with!

O prophetae, quomodo futura praedicere potestis ante tempus et sine scientia omnium quae in vitae via invenientur?

There are lots of great Aesop's fables that make fun of would-be prophets - plus, here is a funny little anecdotes about Rex Ludovicus and his astrologers (more about this story), who are no less well-informed than the average donkey:

Ludovīcus, rēx Gallōrum, fidem māximam habēbat eī generī hominum, quī astrologī vocantur, quod mōtū stellārum imbrēs ventōsque praedīcere solent. Rēx, quī multum in vēnātiōnibus erat, aliquandō dum māgnum cervum canibus per silvās agitat, celerī equō longē ante omnēs sociōs praetervectus est. Intereā caelum nūbibus obscūrātur, gravisque imber cum multā grandine in terram dēcidit. Rēx igitur, quod parvam casam inter arborēs videt, tempestātis perfugium petit. Tum ubi is graviter incūsābat indoctōs illōs astrologōs, "Nūlla tamen tempestās," respondit agricola cūius casa erat, "mē incautum excipit; semper enim meus asinus, quī frūgēs hortī ad forum portāre solet, vōce raucā imbrem mihi praedīcit." "Nīmīrum," cum rīsū respondit rēx, "si tuus asinus tam bonus astrologus est, meōs astrologōs posthāc in numerō asinōrum habēbō."
