Eudoxus of Cnidus ( ; Greek: Εὔδοξος ὁ Κνίδιος , "Eúdoxos ho Knídios"; c. 390– c. 337 BC) was a Greek astronomer, mathematician, scholar and student of Plato.
 All of his works are lost, though some fragments are preserved in Hipparchus' commentary on Aratus's poem on astronomy.
 Theodosius of Bithynia's important work, "Sphaerics", may be based on a work of Eudoxus.
Harpalus was an ancient Greek astronomer (flor.
 82nd Olympiad, ca.450 BC) who corrected the cycle of Cleostratus and invented the Nine Year Cycle.
 He may also have been the engineer Harpalus who designed a pontoon bridge solution when Xerxes wished his army to cross the Hellespont.
On Sizes and Distances (of the Sun and Moon) (Περὶ μεγεθῶν καὶ ἀποστημάτων [ἡλίου καὶ σελήνης], "Peri megethon kai apostematon") is a text by the ancient Greek astronomer Hipparchus.
 It is not extant, but some of its contents have been preserved in the works of Ptolemy and his commentator Pappus of Alexandria.
 Several modern historians have attempted to reconstruct the methods of Hipparchus using the available texts.
Callippus ( ; Ancient Greek: Κάλλιππος ; c. 370 BC – c. 300 BC) was a Greek astronomer and mathematician.
For astronomy and calendar studies, the Metonic cycle or Enneadecaeteris (from Ancient Greek: ἐννεακαιδεκαετηρίς , "nineteen years") is a period of very close to 19 years that is nearly a common multiple of the solar year and the synodic (lunar) month.
 The Greek astronomer Meton of Athens (fifth century BC) observed that a period of 19 years is almost exactly equal to 235 synodic months and, rounded to full days, counts 6,940 days.
 The difference between the two periods (of 19 years and 235 synodic months) is only a few hours, depending on the definition of the year.
On the Sizes and Distances (of the Sun and Moon) (Περὶ μεγεθῶν καὶ ἀποστημάτων [ἡλίου καὶ σελήνης], "Peri megethon kai apostematon") is widely accepted as the only extant work written by Aristarchus of Samos, an ancient Greek astronomer who lived circa 310–230 BC.
 This work calculates the sizes of the Sun and Moon, as well as their distances from the Earth in terms of Earth's radius.
Aristarchus of Samos ( ; Greek: Ἀρίσταρχος ὁ Σάμιος , "Aristarkhos ho Samios"; c. 310 – c. 230 BC) was an ancient Greek astronomer and mathematician who presented the first known model that placed the Sun at the center of the known universe with the Earth revolving around it (see Solar system).
 He was influenced by Philolaus of Croton, but Aristarchus identified the "central fire" with the Sun, and he put the other planets in their correct order of distance around the Sun.
 Like Anaxagoras before him, he suspected that the stars were just other bodies like the Sun, albeit further away from Earth.
 He was also the first one to deduce the rotation of earth on its axis.
 His astronomical ideas were often rejected in favor of the incorrect geocentric theories of Aristotle and Ptolemy.
 Nicolaus Copernicus had attributed the heliocentric theory to Aristarchus.
Aglaonice or Aganice of Thessaly (Ancient Greek: Ἀγλαονίκη , "Aglaoníkē") was a Greek astronomer of the 2nd or 1st century BC.
 She is mentioned in the writings of Plutarch and in the scholia to Apollonius of Rhodes as a female astronomer and as the daughter of Hegetor (or Hegemon) of Thessaly.
 She was regarded as a sorceress for her ability to make the Moon disappear from the sky, which has been taken to mean she could predict the time and general area where a lunar eclipse would occur.
Sir Thomas Little Heath ( ; 5 October 1861 – 16 March 1940) was a British civil servant, mathematician, classical scholar, historian of ancient Greek mathematics, translator, and mountaineer.
 He was educated at Clifton College.
 Heath translated works of Euclid of Alexandria, Apollonius of Perga, Aristarchus of Samos, and Archimedes of Syracuse into English.
An oenochoe, also spelled oinochoe (Ancient Greek: οἰνοχόη ; from Ancient Greek: οἶνος "oînos", "wine" and Ancient Greek: wikt:χέω "khéō", "I pour"; plural "oenochoai" or "oinochoai"), is a wine jug and a key form of ancient Greek pottery.
 There are many different forms of oenochoe; Sir John Beazley distinguished ten types.
 The earliest is the olpe (ὀλπή, "olpḗ"), with no distinct shoulder and usually a handle rising above the lip.
 The "type 8 "oenochoe"" is what one would call a mug, with no single pouring point and a slightly curved profile.
 The chous (χοῦς; pl.
 choes) was a squat rounded form, with trefoil mouth.
 Small examples with scenes of children, as in the example illustrated, were placed in the graves of children.

Question: Sir Thomas Little Heath works of what ancient Greek astronomer and mathematician?
Answer: Aristarchus of Samos
