MACRONS. Here is the text with macrons:
Cum leō vēnātum īret, sociī eius erant canis et lupus. Leō, cum partēs praedae aequālēs factae essent, ita locūtus est: Prīmam partem capiō, quia rēx vester sum; secundam, quia fortis sum, mihi dabitis; tertiam quī tetigerit mē inimīcum sibi habēbit. Ita leō tōtam praedam sōlus abstulit. Haec fābula docet, quam perīculōsum sit societātēs cum potentiōribus inīre.
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):
Cum leo venátum iret, sócii eius erant canis et lupus. Leo, cum partes praedae aequáles factae essent, ita locútus est: Primam partem cápio, quia rex vester sum; secúndam, quia fortis sum, mihi dábitis; tértiam qui tetígerit me inimícum sibi habébit. Ita leo totam praedam solus ábstulit. Haec fábula docet, quam periculósum sit societátes cum potentióribus iníre.
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:
Cum leo venatum iret,
socii eius erant canis et lupus.
Leo,
cum partes praedae
aequales factae essent,
ita locutus est:
"Primam partem capio,
quia rex vester sum;
secundam,
quia fortis sum,
mihi dabitis;
tertiam qui tetigerit
me inimicum sibi habebit."
Ita leo
totam praedam
solus abstulit.
Haec fabula docet,
quam periculosum sit
societates cum potentioribus inire.
