READ OUT LOUD. Choose which marked text you prefer to practice with - macrons in verse form, or macrons in prose order, or accent marks in prose order, or focusing on the meter. You will find materials for all of these options below. :-)
VERSE MACRONS. Here is the verse text with macrons (note short first a in fabricam):
Excūsōris iners fabricam quī irrepserat, Anguis

Saucia lambendō cuī lingua cruōre madēbat,

Facta putāns ā sē dūrō quia vulnera ferrō

Lingendī nōn ante facit temerāria fīnem,

Sunt sua quōs adeō facit īnsānīre cupīdo,

PROSE MACRONS. Here is the same text with macrons written out in prose word order:
Anguis iners, quī excūsōris fabricam irrepserat, iam līmam, quam dabat illa, lingere parat, cuī lambendō lingua saucia cruōre madēbat; rēs ea falsa spem dē successū facit. Quia putāns dūrō ferrō vulnera ā sē facta, stulta pergit, et haud limae, sed sibi nocet. Temerāria fīnem lingendī nōn facit, ante quam hōc modō sibi lingua absumpta fuit. Sunt quōs cupīdo sua facit adeō īnsānīre ut ipsī soleant rēbus suīs obesse.
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):
Anguis iners, qui excusóris fábricam irrépserat, iam limam, quam dabat illa, língere parat, cui lambéndo língua saúcia cruóre madébat; res ea falsa spem de succéssu facit. Quia putans duro ferro vúlnera a se facta, stulta pergit, et haud limae, sed sibi nocet. Temerária finem lingéndi non facit, ante quam hoc modo sibi lingua absúmpta fuit. Sunt quos cupído sua facit ádeo insaníre ut ipsi sóleant rebus suis obésse.

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: Anguis iners, qui excusoris fabricam irrepserat, iam limam, quam dabat illa, lingere parat, cui lambendo lingua saucia cruore madebat; res ea falsa spem de successu facit. Quia putans duro ferro vulnera a se facta, stulta pergit, et haud limae, sed sibi nocet. Temeraria finem lingendi non facit, ante quam hoc modo sibi lingua absumpta fuit. Sunt quos cupido sua facit adeo insanire ut ipsi soleant rebus suis obesse.
