MACRONS. Here is the text with macrons:
Rānae aliquandō rēgem sibi ā Iove petīvisse dīcuntur. Quārum ille precibus exōrātus trabem ingentem in lacum dēiēcit. Rānae sonitū perterritae prīmum refūgēre, deinde vērō, trabem in aquā nātantem cōnspicātae, māgnō cum contemptū in eā cōnsēdērunt aliumque sibi novīs clāmōribus rēgem expetīvērunt. Tum Iupiter, eārum stultitiam pūnītūrus, hydrum illīs mīsit, ā quō cum plūrimae captae perīrent, sērō eās stolidārum precum paenituit.
ACCENT MARKS. Here is the text with ecclesiastical accents, plus some color-coding for the words of three or more syllables (blue: penultimate stress; red: antepenultimate stress):
Ranae aliquándo regem sibi a Iove petivísse dicúntur. Quárum ille précibus exorátus trabem ingéntem in lacum deiécit.

Tum Iúpiter, eárum stultítiam punitúrus, hydrum illis misit, a quo cum plúrimae captae perírent, sero eas stolidárum precum paenítuit.

Ranae aliquando
regem sibi
a Iove petivisse dicuntur.
Quarum ille precibus exoratus
trabem ingentem
in lacum deiecit.
Ranae sonitu perterritae
primum refugere,
deinde vero,
trabem in aqua natantem
conspicatae,
magno cum contemptu
in ea consederunt
aliumque sibi novis clamoribus regem
expetiverunt.
Tum Iupiter,
earum stultitiam puniturus,
hydrum illis misit,
a quo
cum plurimae captae perirent,
sero eas
stolidarum precum paenituit.
