Vibilius or Vibillius (flourished in 1st century AD) was a powerful king of the Hermunduri in the 1st century AD, mentioned in The Annals of the Roman historian Tacitus.
 According to Tacitus, Vibilius deposed the Marcomannic king Catualda, who had himself deposed Maroboduus in 18 AD.
 Catualda was subsequently succeeded by the Quadian client king Vannius.
 In 50 AD however, along with Vannius' nephews Vangio and Sido and allied Lugii, Vibilius also in turn led the deposition of Vannius.
Mount Ptolemy ( ) is an isolated block mountain with four main summits, the highest rising to 1,370 meters.
 It lies close north of the Traffic Circle on the northwestern side of Mercator Ice Piedmont, Antarctic Peninsula.
 First observed by Finn Ronne and Carl Eklund of the U.S. Antarctic Service, 1939–41, from their sledge route through the Traffic Circle.
 Surveyed by Falkland Islands Dependencies Survey (FIDS) in 1947.
 Named by United Kingdom Antarctic Place-Names Committee (UK-APC) after Claudius Ptolemy (2nd century AD), Egyptian mathematician, astronomer and geographer, who introduced the system of coordinates of latitude and longitude for fixing positions on the Earth's surface.
The Hilleviones were a Germanic people occupying an island called "Scatinavia" in the 1st century AD, according to the Roman geographer Pliny the Elder in Naturalis Historia (Book 4, Chapter 96), written circa 77 AD.
 Pliny's Scatinavia is generally believed to have referred to the Scandinavian peninsula, which in the 1st century AD had not yet been fully explored by the Romans and was therefore described as an island.
 Pliny wrote that it was an island "of a magnitude as yet unascertained".
 The Hilleviones lived in the only part of the island that was known, and according to Pliny, they thought of their 500 villages as a separate ("alterum") world.
Vangio and Sido (flourished in 1st century AD) were two Quadian brothers who were the co-rulers of a Roman client kingdom in Bohemia in the 1st century AD.
The Sanni (Georgian: სანები ) are mentioned by Strabo (1st century BC/1st century AD), Pliny the Elder (1st century AD) and Arrian (2nd century AD) as a people settling near Trebizond (in today's Turkish Black Sea Region).
The 1st century was the century that lasted from AD 1 to AD 100 according to the Julian calendar.
 It is often written as the 1st century AD or 1st century CE to distinguish it from the 1st century BC (or BCE) which preceded it.
 The 1st century is considered part of the Classical era, epoch, or historical period.
Hero of Alexandria ( ; Greek: Ἥρων ὁ Ἀλεξανδρεύς , "Heron ho Alexandreus"; also known as Heron of Alexandria ; c. 10 AD – c. 70 AD) was a mathematician and engineer who was active in his native city of Alexandria, Roman Egypt.
 He is considered the greatest experimenter of antiquity and his work is representative of the Hellenistic scientific tradition.
Roman Armenia refers to the rule of parts of Greater Armenia by the Roman Empire, from the 1st century AD to the end of Late Antiquity.
 While Armenia Minor had become a client state and incorporated into the Roman Empire proper during the 1st century AD, Greater Armenia remained an independent kingdom under the Arsacid dynasty.
 Throughout this period, Armenia remained a bone of contention between Rome and the Parthian Empire, as well as the Sasanian Empire that succeeded the latter, and the casus belli for several of the Roman–Persian Wars.
 Only in 114–118 was Emperor Trajan able to conquer and incorporate it as a short-lived province.
Roman glass objects have been recovered across the Roman Empire in domestic, industrial and funerary contexts.
 Glass was used primarily for the production of vessels, although mosaic tiles and window glass were also produced.
 Roman glass production developed from Hellenistic technical traditions, initially concentrating on the production of intensely coloured cast glass vessels.
 However, during the 1st century AD the industry underwent rapid technical growth that saw the introduction of glass blowing and the dominance of colourless or ‘aqua’ glasses.
 Production of raw glass was undertaken in geographically separate locations to the working of glass into finished vessels, and by the end of the 1st century AD large scale manufacturing resulted in the establishment of glass as a commonly available material in the Roman world, and one which also had technically very difficult specialized types of luxury glass, which must have been very expensive.
The Mishnat ha-Middot (Hebrew: מִשְׁנַת הַמִּדּוֹת‎ ‎ ; "treatise of measures") is considered the earliest known Hebrew treatise on geometry.
 The treatise was discovered in the Munich Library by Moritz Steinschneider, who dated it between 800 and 1200 C.E. Hermann Schapira argued the treatise dates from an earlier period and Solomon Gandz conjectured Rabbi Nehemiah (c. 150 C.E.) to be the author.
 The content resembles both the work of Hero of Alexandria (c. 100 C.E.) and that of al-Khwārizmī (c. 800 C.E.) and the proponents of the earlier dating therefore see it linking Greek and Islamic mathematics.

Question: The content of the Mishnat ha-Middot resembles the work of this 1st Century AD Egyptian mathematician.
Answer: Hero of Alexandria
