This from Orberg’s adapted Livy (LLPSI).
Tarquinius has given a speech explaining why he should be the next king, recounting his learning of Roman rituals and laws.
Haec eum haud falsa memorantem ingenti consensu populus Romanus regnare iussit.
There is a translation of this in Perseus which goes: "While he was recounting these undoubted facts, the people by a great majority elected him king. "
Is a more literal translation
The people of Rome commanded him, recalling these undoubetly true things, to rule. (?)
What has me confused is haec Given that memorantem is an accusative participle - can a participle retain it’s own object - haec (accusative plural neuter)?
