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 iambic meter. You will find materials for all of these options below. :-)
VERSE MACRONS. Here is the verse text with macrons:
Pāstor capellae cornū baculō frēgerat:
rogāre coepit nē sē dominō prōderet.
"Quamvīs indīgnē laesa reticēbō tamen;
sed rēs clāmābit ipsa quid dēlīqueris."
PROSE MACRONS. Here is the same text with macrons written out in prose word order:
Pāstor capellae cornū baculō frēgerat; rogāre coepit nē sē dominō prōderet. "Quamvīs indīgnē laesa, reticēbō tamen; sed rēs ipsa clāmābit quid dēlīqueris."
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):
Pastor capéllae cornu báculo frégerat; rogáre coepit ne se dómino próderet. "Quamvis indígne laesa, reticébo tamen; sed res ipsa clamábit quid delíqueris."
IAMBIC METER. Here is the verse text with some color coding to assist in the iambic meter. The disyllabic elements (iambs/spondees) are not marked, but the trisyllabic elements are color-coded: dactyls are red, anapests are purple, and tribrachs are green (as is any proceleusmaticus, although that is a rare creature); for more information, here are some Notes on Iambic Meter.
Pāstor· capel·lae cor·nū bacu·lō frē·gerat:
rogā·re coe·pit nē· sē domi·nō prō·deret.
"Quamvīs· indīg·nē lae·sa reti·cēbō· tamen;
sed rēs· clāmā·bit ip·sa quid· dēlī·queris."
IMAGE. Here is an illustration for the story (image source).
What follows is an unmarked version of the prose rendering to faciliate word searches:
Pastor capellae cornu baculo fregerat; rogare coepit ne se domino proderet. "Quamvis indigne laesa, reticebo tamen; sed res ipsa clamabit quid deliqueris."
