MACRONS. Here is the text with macrons:
Canis iacēbat in praesēpī bovēsque lātrandō ā pābulō arcēbat. Cuī ūnus boum, Quanta ista, inquit, invidia est, quod nōn pateris, ut eō cibō vescāmur, quem tū ipse capere nec velīs nec possīs!
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):
Canis iacébat in praesépi bovésque latrándo a pábulo arcébat. Cui unus boum, Quanta ista, inquit, invídia est, quod non páteris, ut eo cibo vescámur, quem tu ipse cápere nec velis nec possis!
