Ulpian (Domitius Ulpianus)

Ulpian (Domitius Ulpianus), a Roman jurist, assassinated at Rome, A. D. 228. He was of Tyrian origin, and during the reigns of Septimius Severus and Caracalla wrote juristical works. When Elagabalus ascended the throne in 218 he was banished, but in 222 he became one of the chief advisers of Alexander Severus, who made him Scriniorum magister, comiliarius, and proefectus annonoe. He also held the office of praetorian prefect. He was killed by the soldiers in the presence of the emperor and his mother. Ulpian was one of the most distinguished of the Roman jurists, and from his works were taken about one third of the excerpts made for Justinian's Digest.

Umber

Umber, a pigment much used by artists for brown and grave colors. It is made from an argillaceous brown hematite having the formula 2Fe203,3H20, by roasting, pulverizing, and mixing it with variable proportions of clay or ochre, and sometimes with a little oxide of manganese, or it may be used alone. Ordinary roasting does not drive off all the water, and in this state it is called raw umber. When strongly heated it is completely dehydrated, and is called burnt umber. It is used both in oil and water colors, and is often mixed with other pigments.
