VERSE MACRONS. Here is the verse text with macrons:
Fūr plācāre Canem lātrantem nocte labōrat,

Cuī Canis ut nunc sim pastū satiātus herīlī,

Īnsidiōse domum sī tē spoliante tacērem,

Āversēre dolōs fac impostōris et artēs,

Cōnsilium spectā, nōn facta tegentia fraudem,

PROSE MACRONS. Here is the same text with macrons written out in prose word order:
Nocte Fūr labōrat Canem lātrantem plācāre, quem putat silēre velle, cibō oblātō. Cuī Canis: Ut nunc pastū herīlī satiātus sim, cuius mūnere nōn parcē alī soleō: īnsidiōse domum sī tē spoliante tacērem, unde postmodo cibum petam, vacuō ventre? Fac āversēre impostōris dolōs et artēs; rārō nōris fīdem blanditiīs inesse. Cōnsilium spectā, nōn facta fraudem tegentia; ille arte īnsidiīs suīs vacāre scit.
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):
Nocte Fur labórat Canem latrántem placáre, quem putat silére velle, cibo obláto. Cui Canis: Ut nunc pastu heríli satiátus sim, cuius múnere non parce ali sóleo: insidióse domum si te spoliánte tacérem, unde póstmodo cibum petam, vácuo ventre? Fac aversére impostóris dolos et artes; raro noris fidem blandítiis inésse. Consílium specta, non facta fraudem tegéntia; ille arte insídiis suis vacáre scit.

IMAGE. Here is an illustration for the story from the 1574 edition of Osius:
What follows is an unmarked version of the prose rendering to faciliate word searches: Nocte Fur laborat Canem latrantem placare, quem putat silere velle, cibo oblato. Cui Canis: Ut nunc pastu herili satiatus sim, cuius munere non parce ali soleo: insidiose domum si te spoliante tacerem, unde postmodo cibum petam, vacuo ventre? Fac aversere impostoris dolos et artes; raro noris fidem blanditiis inesse. Consilium specta, non facta fraudem tegentia; ille arte insidiis suis vacare scit.
