VERSE MACRONS. Here is the verse text with macrons:
Hystrice vescendī pervāsit forte cupīdo

Ast illa hirsūtīs spīnīs mūnīta manēbat

Intereā, bellō cum vincere nescit apertō,

"Tempore nē pācis cūrēs tua tēla tulisse;

Īnsidiātor ait; cuī tālia rettulit Hystrix,

PROSE MACRONS. Here is the same text with macrons written out in prose word order:
Forte, cupīdo summa Hystrice vescendī Lupum pervāsit; ēsuries īnsatiāta premit. Ast Hystrix illa hirsūtīs spīnīs undique mūnīta manēbat; Lupus ardēns adīre nōn audet. Intereā, cum vincere nescit bellō apertō, fraude et dolō petit (quod illī superest). "Nē cūrēs tua tēla tulisse pācis tempore; nam, nisi Mars īnstat, mīles sua tela nōn habet" īnsidiātor ait; cuī Hystrix tālia rettulit: "Quā lupus est, illīc tēla tenēre decet."
STRESS (ACCENT) MARKS. Here is the prose text with accents, plus some color-coding for the words of three or more syllables (blue: penultimate stress; red: antepenultimate stress):
Forte, cupído summa Hýstrice vescéndi Lupum pervásit; esúries insatiáta premit. Ast Hystrix illa hirsútis spinis úndique muníta manébat; Lupus ardens adíre non audet. Intérea, cum víncere nescit bello apérto, fraude et dolo petit (quod illi súperest). "Ne cures tua tela tulísse pacis témpore; nam, nisi Mars instat, miles sua tela non habet" insidiátor ait; cui Hystrix tália réttulit: "Qua lupus est, illic tela tenére decet."

IMAGE. Here's an illustration for the fable (image source) showing a high-spirited hedgehog:
What follows is an unmarked version of the prose rendering to faciliate word searches: Forte, cupido summa Hystrice vescendi Lupum pervasit; esuries insatiata premit. Ast Hystrix illa hirsutis spinis undique munita manebat; Lupus ardens adire non audet. Interea, cum vincere nescit bello aperto, fraude et dolo petit (quod illi superest). "Ne cures tua tela tulisse pacis tempore; nam, nisi Mars instat, miles sua tela non habet" insidiator ait; cui Hystrix talia rettulit: "Qua lupus est, illic tela tenere decet."
