Licinius Crassus is described as being well-versed in pontifical law; he is shown by Livy as reminding Romans of their religious duties repeatedly (particularly after the conclusion of the Second Punic War).
However, like his future political ally Scipio (and a few other young Roman aristocrats of the same era such as Publius Sempronius Tuditanus), Licinius Crassus was elected young to important positions, being chosen to certain positions over those of greater age and seniority in the political arena.
He was known for his learning in pontifical law, his great bodily strength, and his military skills (although he never won a triumph).
Licinius Crassus is perhaps best known for his refusal to leave Italy, as Fabius wanted, which allowed his co-consul Scipio to take Sicily as his province and eventually invade Africa.
He was ill at the end of his year and so requested that a dictator be appointed to conduct elections since neither consul was able to be present.
Descendants of Publius Licinius Crassus Dives Pontifex Maximus include: Other famous Licinii such as Lucius Licinius Crassus (consul 95 BC, censor, died 91 BC) and Licinia Crassa (wife successively of two consuls, Quintus Mucius Scaevola Pontifex and Quintus Caecilius Metellus Nepos, and mother of Mucia Tertia) may be descendants.
