Lucius Neratius Priscus
Lucius Neratius Priscus was a Roman Senator and leading jurist, serving for a time as the head of the Proculian school.
He was suffect consul in the" nundinium" of May- June 97 as the colleague of Marcus Annius Verus.
Marcus Annius Verus (II)
Marcus Annius Verus( II)( 50 – 138 AD) was the grandfather and adoptive father of the Roman Emperor Marcus Aurelius, and father- in- law of Emperor Antoninus Pius.
He was prefect of Rome and was enrolled as a patrician when Vespasian and Titus were censors.
Verus was three times consul, the first time as a suffect in 97, then as ordinary consul in both 121 and 126.
This is apparently the cause for a" very strange inscription, found on a large marble tablet excavated in the sixteenth century at St. Peter's in Rome" which alludes to this achievement while celebrating his skill" playing with a glass ball".
Edward Champlin notes it was likely the creation of a friendly rival, Lucius Julius Ursus Servianus, who also held the consulate three times the last after Verus.
Verus was the son of an elder Marcus Annius Verus, who gained the rank of senator and praetor.
His family originated from Uccibi( modern Espejo) near Corduba( modern Córdoba) in the Roman province of Hispania Baetica.
The family came to prominence and became wealthy through olive oil production in Spain.
He was close friends with the emperor Hadrian.
He died in 138, nearly aged ninety.
Marcus Aurelius says in his" Meditations From my grandfather Verus,[ I learned] a kindly disposition and sweetness of temper".
In his elder years, he had a mistress, of whom he expresses gratitude that" I was n’t raised by my grandfather's mistress for longer than I was".

Marcus Aurelius
Marcus Aurelius( or;; 26 April 121 – 17 March 180) was Roman emperor from 161 to 180 and a Stoic philosopher.
He was the last of the rulers known as the Five Good Emperors, and the last emperor of the Pax Romana, an age of relative peace and stability for the Roman Empire.
He served as Roman consul in 140, 145, and 161.
The son of the praetor Marcus Annius Verus( III) and the wealthy heiress Domitia Lucilla, Marcus was raised by his mother and by his grandfather, Marcus Annius Verus( II), after his father died.
His uncle, Antoninus Pius, adopted him shortly before becoming emperor in 138.
Now heir to the throne, Marcus studied Greek and Latin under tutors such as Herodes Atticus and Marcus Cornelius Fronto.
He kept in close correspondence with Fronto for many years afterwards.
Marcus married Antoninus' daughter Faustina in 145.
Antoninus died following an illness in 161.
The reign of Marcus Aurelius was marked by military conflict.
In the East, the Roman Empire fought successfully with a revitalized Parthian Empire and the rebel Kingdom of Armenia.
Marcus defeated the Marcomanni, Quadi, and Sarmatian Iazyges in the Marcomannic Wars; however, these and other Germanic peoples began to represent a troubling reality for the Empire.
He modified the silver purity of the Roman currency, the denarius.
The persecution of Christians in the Roman Empire is believed to have increased during his reign.
The Antonine Plague broke out in 165 or 166 and devastated the population of the Roman Empire, causing the deaths of five million people.
Unlike some of his predecessors, Marcus chose not to adopt an heir.
His children included Lucilla( who married Lucius Verus, co-emperor from 161 to 169) and Commodus, whose succession after Marcus has become a subject of debate among both contemporary and modern historians.
The Column and Equestrian Statue of Marcus Aurelius still stand in Rome, where they were erected in celebration of his military victories.
" Meditations", the writings of" the philosopher" – as contemporary biographers called Marcus, are a significant source of the modern understanding of ancient Stoic philosophy.
They have been praised by fellow writers, philosophers, monarchs, and politicians centuries after his death.
