Semen /ʂemen/ or Xemen /ʃemen/ is a medieval Basque given name of the Vasconic area. It is based on the Basque root seme < senbe 'son' as found in the ancient Aquitanian name Sembetten, attested form "sehi" as 'child', hypothetical ancient root *seni (cf. Koldo Mitxelena and modern form "senide" = 'brother or sister', 'relative'). The explanation by the Biblical name Šim’ōn (Simon) is less convincing. Some think the name may be a corruption of the later part of the Latin name Ma-ximinus, as there are late Classic records that various individuals with this name were becoming very active as officials and residents in upper Hispania near the Pyrenees and Tarraconensis during the last century of the Western Roman Empire, and perhaps into the period of transition from imperial province to independent Kingdom during Visigothic rule. A "Seguin" was attested in Frankish chronicles when referring to the Count of Bordeaux and Duke of Vasconia (778, 814 and 816). The name is also recorded as Sihiminus, perhaps a rendering of Ximinus. He may have been a local Basque whose family later fled south over the Pyrenees and helped Enneco Arista take over in Pamplona. Arab sources in Al-Andalus report in 778 a "Jimeno, the strong", calling him "Mothmin al-Akra". He was a Basque or Hispanic magnate in the upper Ebro territories within the later independent principality of Navarre. This person was possibly related to others near Pamplona in local opposition to both the invading Franks under Charlemagne and the new ruler of the Islamic Iberian realm, Abd al-Rahman I. Other than these early medieval examples, it is widely known on both sides of the Pyrenees in the following forms: Semen or Semeno fem. Semena Semero fem. Semera Scemeno (in Villabáscones) Xemen or Xemeno fem. Xemena Ximeno or Jimeno fem. Ximena or Jimena (French Chimène) By adjunction of the patronymic suffixes -ez or -es, it produces the Iberian patronyms: Portuguese: Ximenes Spanish: Ximénez, Giménez, Jiménez Cyrillic transliteration Semen is also a transliteration of the Russian given name (Semyon, a variant of —Simon) and the Ukrainian given name (Semen). Notable persons with that name include: Semen Altman (born 1946), Ukrainian football coach Semen Bogdanov (1894–1960), Soviet Marshal of the Army Semen Hulak-Artemovsky (1813–1873), Ukrainian opera composer, singer, actor, and dramatist Semen Kirsanov (1906–1972), Ukrainian poet in Russia Semen Korsakov (1787–1853 OS), inventor who was involved with an early version of information technology Semen
