SOURCE: You can find Francis Barlow's illustrated edition of Aesop's fables (1687 edition) available online at Michigan State University. I've also transcribed the fables at the Aesopus wiki, with page images at Aesopica.net. This is fable 15 in Barlow. For parallel versions, see Perry 572 and Perry 506.
READ OUT LOUD. Choose which marked text you prefer to practice with - macrons or accent marks - and read the text out loud until you feel comfortable and confident. Then, try reading the unmarked text at the bottom. It should be easy for you after practicing with the marked texts. :-)
MACRONS. Here is the text with macrons:
Agnō comitantī Caprum Lupus fit obviam, rogatque cūr relictā Mātre olidum sequātur hircum, suādetque ut ad ūbera Mātris distenta lacte redeat. Ille vērō, Māter mea huic hircō, Ō Lupe, commīsit. Huic summa cūra meae salūtis data est. Parentī potius quam tibi obsequendum, quī mē sēdūcere istīs dictīs quaeris, et subductum posteā dēcerpere.
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):
Agno comitánti Caprum Lupus fit óbviam, rogátque cur relícta Matre ólidum sequátur hircum, suadétque ut ad úbera Matris disténta lacte rédeat. Ille vero, Mater mea huic hirco, O Lupe, commísit. Huic summa cura meae salútis data est. Parénti pótius quam tibi obsequéndum, qui me sedúcere istis dictis quaeris, et subdúctum póstea decérpere.
UNMARKED TEXT. Here is the unmarked text - after practicing with the marked text that you prefer, you should not have any trouble with the unmarked text:
