He was surnamed Philoromaeus (Φιλορώμαιος, meaning Lover of Rome) and is usually believed to have lived about the time of Cicero and Julius Caesar.
[2] A partiality to the Romans is suggested by the surname Philoromaeus, and may have been evident in a work mentioned by Plutarch[3] as comparing the institutions of Rome with those of Pythagoras.
This appears to be the same Castor, mentioned by Strabo,[4] who was surnamed Saecondarius, was a son-in-law of Deiotarus, and was put to death by him.
Because of this circumstance, one conclusion is that the rhetorician Castor must have lived at or before the time of Apollodorus, around 150 BC, and thus had no connection with the Deiotarus for whom Cicero spoke.
[6] Another common conclusion, which assumes Castor of Rhodes really was contemporary with Caesar and Cicero, is that Bibliotheke could not have been written by Apollodorus, hence the appellation "Pseudo-Apollodorus" for this work.
