Skinny Puppy is a Canadian industrial music group formed in Vancouver, British Columbia in 1982. The group is widely considered to be one of the founders of the electro-industrial genre. Initially envisioned as an experimental side project by cEvin Key (Kevin Crompton) while he was in the new wave band Images in Vogue, Skinny Puppy evolved into a full-time project with the addition of vocalist Nivek Ogre (Kevin Ogilvie). Over the course of a dozen studio albums and many live tours, Key and Ogre have been the only constant members.
Skinny Puppy is noted for theatrical and controversial live performances which blend performance art with music, especially in an ambitious period that spanned their Head Trauma (1987-1988), VIVIsectVI (1988), Too Dark Park (1990), and Last Rights (1992) tours. Ogre has been critical of the bands early performances, telling Spin magazine in 1992 that "I would do things on stage that would blow-they just wouldn't work". Live performances involved periods of musical improvisation, film projections, and elaborate stage props and machines, many of which are designed and built by Ogre himself. While discussing Skinny Puppy's performances, Ogre once remarked that "our shows combine images with theater. It works better than just coming out and doing a horror magic routine". On-stage theatrics included Ogre being suspended from racks and cables, play with a hangman's noose, Key cutting steel with an angle grinder, and mock executions of Ogre and George H.W. Bush. Following the 2004 Presidential Election in the United States, promoters began to ask the band to refrain from using fake blood during their performances. This reaction was prompted by the performance of a mock execution on stage, during which Ogre was decapitated by actors dressed as then U.S. President George W. Bush and Vice President Dick Cheney. The band was also asked by Samsung (who had been asked by Ogre to sponsor the band with a large flat screen) to "not insult the president" while performing on stage. In a 1987 television interview with Kim Clarke Champniss, Key explained that while Ogre follows a "rough guideline" during a live performance, a majority of his on-stage theatrics are thought up of spontaneously. Key told Champniss that Ogre's demeanor on stage could "range from just a sort of laid back kind of lurking to a rampant psycho". Ogre once remarked that touring was, for himself, like "dating hydrogen peroxide", referencing the numerous injuries which he would acquire over the course of touring. Though Ogre and Key have remained the only constant members of Skinny Puppy's live act since the death of Dwayne Goettel, several other musicians have been hired to accompany the pair since 2004. They include drummer Justin Bennett, guitarist William Morrison, and guitarist Matthew Setzer.

Answer the question at the end by quoting:

Claudius Ptolemy (; Greek: Klaudios Ptolemaios, Klaudios Ptolemaios [klawdios ptoleme:os]; Latin: Claudius Ptolemaeus; c. AD 100 - c. 170) was a Greco-Roman mathematician, astronomer, geographer, astrologer, and poet of a single epigram in the Greek Anthology. He lived in the city of Alexandria in the Roman province of Egypt, wrote in Koine Greek, and held Roman citizenship. The 14th-century astronomer Theodore Meliteniotes gave his birthplace as the prominent Greek city Ptolemais Hermiou
Ptolemaeus (Ptolemaios - Ptolemaios) is a Greek name. It occurs once in Greek mythology, and is of Homeric form. It was common among the Macedonian upper class at the time of Alexander the Great, and there were several of this name among Alexander's army, one of whom made himself King of Egypt in 323 BC: Ptolemy I Soter. All the kings (Pharaohs) after him, until Egypt became a Roman province in 30 BC, were also Greek Ptolemies. The name Claudius is a Roman nomen; the fact that Ptolemy bore it indicates he lived under the Roman rule of Egypt with the privileges and political rights of Roman citizenship. It would have suited custom if the first of Ptolemy's family to become a citizen (whether he or an ancestor) took the nomen from a Roman called Claudius who was responsible for granting citizenship. If, as was common, this was the emperor, citizenship would have been granted between AD 41 and 68 (when Claudius, and then Nero, were Roman emperors). The astronomer would also have had a praenomen, which remains unknown. The 9th-century Persian astronomer Abu Ma'shar presents Ptolemy as a member of Egypt's royal lineage, stating that the ten kings of Egypt who followed Alexander were wise "and included Ptolemy the Wise, who composed the book of the Almagest". Abu Ma'shar recorded a belief that a different member of this royal line "composed the book on astrology and attributed it to Ptolemy". We can evidence historical confusion on this point from Abu Ma'shar's subsequent remark "It is sometimes said that the very learned man who wrote the book of astrology also wrote the book of the Almagest. The correct answer is not known". There is little evidence on the subject of Ptolemy's ancestry, apart from what can be drawn from the details of his name (see above); however, modern scholars refer to Abu Ma'shar's account as erroneous, and it is no longer doubted that the astronomer who wrote the Almagest also wrote the Tetrabiblos as its astrological counterpart. Ptolemy wrote in Greek and can be shown to have utilized Babylonian astronomical data. He was a Roman citizen, but was ethnically either a Greek or a Hellenized Egyptian. He was often known in later Arabic sources as "the Upper Egyptian", suggesting he may have had origins in southern Egypt. Later Arabic astronomers, geographers and physicists referred to him by his name in Arabic: baTlumyws Batlamyus.
