Background: Napalm Death are a British extreme metal band formed in Meriden, West Midlands, England, in 1981. While none of its original members remain in the group since December 1986, the lineup of vocalist Mark "Barney" Greenway, bassist Shane Embury, guitarist Mitch Harris and drummer Danny Herrera has remained consistent of the band's career since 1992's Utopia Banished, although, from 1989 to 2004, Napalm Death were a five-piece band after they added Jesse Pintado as the replacement of one-time guitarist Bill Steer; following Pintado's departure, the band reverted to a four-piece rather than replace him. Napalm Death are credited as pioneers of the grindcore genre by incorporating elements of crust punk and death metal, using a noise-filled sound that uses heavily distorted, down-tuned guitars, grinding overdrive bass, high speed tempo, blast beats, and vocals which consist of incomprehensible growls, or high-pitched shrieks, extremely short songs, fast tempos, and sociopolitical lyrics. The band's debut album Scum, released in 1987 by Earache Records, proved substantially influential throughout the global metal community.
Context: With the departure of Broadrick and Bullen, the band had to look for new members. Guitarist Bill Steer played in a band based in Liverpool, called Carcass and given the affinity between the bands, he joined Napalm Death while still playing an active role in Carcass. The band asked a friend, Coventrian (Lee Dorrian), to join as vocalist due to his good relationship with the band (he had organised a number of concerts for the band), even though he had never been in a band before. This line-up recorded the B side of the Scum LP at Rich Bitch studios in May 1987, and the album was released through Earache Records. Bill Steer also came third place on Decibel Magazine's "Top 20 Death Metal guitarists of all time."  The band promptly lost another member just after they undertook a short tour after the release of Scum. Jim Whiteley left the group (and subsequently joined Weston-Super-Mare based band Ripcord with whom the aforementioned tour had been shared) and Shane Embury (former drummer of Unseen Terror) moved to bass. The band then appeared on two compilation records ('North Atlantic Noise Attack' and the 'Pathological Compilation'), recorded two Peel sessions and a split 7" with Japanese band S.O.B. They also returned to Rich Bitch studio once more and recorded their second album: From Enslavement to Obliteration.  A follow-up release to "Enslavement..." came in the form of the six song 12" EP "Mentally Murdered", which was to be the last recording with the Harris/Steer/Dorian/Embury line-up. This EP was recorded at the Slaughterhouse Studios and took on a slightly different sound, blending grindcore with death metal. Following the release, Napalm Death were featured on national television in the United Kingdom in a heavy metal special by Arena (BBC 2).  The band continued to tour, but as soon as they came back home from Japan, in July 1989, Steer and Dorrian left the band: Steer decided to dedicate himself full-time to Carcass, while Dorrian formed the doom metal group Cathedral. The group recruited Jesse Pintado (ex-Terrorizer) on guitar and Mark "Barney" Greenway (ex-Benediction) as vocalist. This line-up took part in the Grindcrusher tour organised by Earache Records and featuring fellow label-mates Carcass, Bolt Thrower and Morbid Angel. The group recruited Mitch Harris (ex-Righteous Pigs) as second guitarist after the tour.

Background: 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
Context: 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.
