was buried alongside his first wife in the Royal Mausoleum of Mauretania. Ptolemy then became the sole ruler of Mauretania. Marriages and children First marriage to Greek Ptolemaic princess Cleopatra Selene II (40 BC – 6 AD). Their children were: Ptolemy of Mauretania born in ca 10 BC/ 5 BC A daughter of Cleopatra and Juba, whose name has not been recorded (based on Roman naming conventions she would have had the nomen "Julia" but like many client royals she may have never used it), is mentioned in an inscription. She is sometimes assumed to have had the same cognomen as her niece Drusilla. Second marriage to Glaphyra, a princess of Cappadocia, and widow of Alexander, son of Herod the Great. Alexander was executed in 7 BC for his involvement in a conspiracy against his father. Glaphyra married Juba II in 6 AD or 7 AD. She then fell in love with Herod Archelaus, another son of Herod the Great and Ethnarch of Judea. Glaphyra divorced Juba to marry him in 7 AD. Works Writings Juba wrote a number of books in Greek on history, natural history, geography, grammar, painting and theatre. He compiled a comparison of Greek and Roman institutions known as Όμοιότητες (Resemblances). His guide to Arabia became a bestseller in Rome. Only fragments of his works survived. He collected a substantial library on a wide variety of topics, which no doubt complemented his own prolific output. Pliny the Elder refers to him as an authority 65 times in the Natural History and in Athens, a monument was built in the Gymnasium of Ptolemy in recognition of his writings. Ten works by Juba II have provisionally been identified, but all are fragmentary: Roman Archaeology, in two books Resemblances, in at least fifteen books On Painting, in at least eight books Theatrical History, in at least seventeen books The Wanderings of Hanno, possibly a translation of the periplus of Hanno the Navigator On Euphorbion, a pamphlet Libyka, in at least three books On Arabia, which is the only work by Juba that may have been in Latin On Assyria, in two books Epigrams, of which six lines of one quoted by Athenaeus are all that survives Juba's works survive only in quotations or citations by others, in both Greek and Latin. There are around 100 of these, about half in Pliny the Elder's Natural History. Others can be found
