Nothing is known about Lucius's early life, except that he was born during the Second Punic War. If his parents married circa 212 BC (possibly earlier or later), and if he had an elder brother, he was probably born around 210 BC or 209 BC when his father was already in Spain. In that case, he would have spent his entire childhood seeing little of his father who was winning Rome territories in Spain and then defeating Hannibal at Zama.
