Aretaeus in Harpers Dictionary of Classical Antiquities
（Ἀπέταιος). A physician of Cappadocia, born near the close of the second century A.D. He was the author of two works, each in four books, on the causes, symptoms, and cure of acute and chronic pains. He wrote in the Ionic dialect with much elegance and clearness; and his treatises show a correctness of understanding with regard to medicine unusual among the ancient writers on this subject. He discourses with especial acuteness of the nerves, of indigestion, and gives an excellent account of diseases of the throat and tonsils. See Mann, Aretaei Therapia (1858).
Aristaeus in Harpers Dictionary of Classical Antiquities
（Ἀρισταῖος). A son of Apollo and Cyrené, was born in Libya. He afterwards went to Thrace, where he fell in love with Eurydicé, the wife of Orpheus. The latter, while fleeing from him, perished by the bite of a serpent; whereupon the Nymphs, in anger, destroyed the bees of Aristaeus. The way in which he recovered his bees is related in the Fourth Georgic of Vergil. After his death he was worshipped as a god, on account of the benefits he had conferred upon mankind. He was regarded as the protector of flocks and shepherds, of vine and olive plantations; he taught men to keep bees, and averted from the fields the burning heat of the sun and other causes of destruction. He is said to have had the care of Dionysus when young.
Aristaeus in Wikipedia
A minor god in Greek mythology, which we read largely through Athenian writers, Aristaeus or Aristaios (Greek: Ἀρισταῖος), "ever close follower of the flocks", was the culture hero credited with the discovery of many useful arts, including bee-keeping; he was the son of Apollo and the huntress Cyrene. Aristeus ("the best") was a cult title in many places: Boeotia, Arcadia, Ceos, Sicily, Sardinia, Thessaly, and Macedonia; consequently a set of "travels" was imposed, connecting his epiphanies in order to account for these widespread manifestations.
If Aristaeus was a minor figure at Athens, he was more prominent in Boeotia, where he was "the pastoral Apollo" and was linked to the founding myth of Thebes by marriage with Autonoe, daughter of Cadmus, the founder. Aristaeus may appear as a winged youth in painted Boeoptian pottery, similar to representations of the Boreads, spirits of the North Wind.
According to Pindar's ninth Pythian Ode and Apollonius' Argonautica (II.522ff), Cyrene despised spinning and other womanly arts and instead spent her days hunting, but, in a prophecy he put in the mouth of the wise centaur Chiron, Apollo would spirit her to Libya and make her the foundress of a great city, Cyrene, in a fertile coastal plain. When Aristaeus was born, Pindar sang, Hermes took him to be raised on nectar and ambrosia and be made immortal by Gaia. The Myrtle-nymphs taught him useful arts and mysteries, how to curdle milk for cheese, how to tame the Goddess's bees and keep them in hives, and how to tame the wild oleaster and make it bear olives. Thus he became the patron god of cattle, fruit trees, hunting, husbandry and bee-keeping. He also taught humanity dairy skills (including cheesemaking) and the use of nets and traps in hunting.
When he was grown, he sailed from Libya to Boeotia, where he was inducted into further mysteries in the cave of Chiron the centaur. In Boeotia, he was married to Autonoe and became the father of the ill-fated Actaeon, who inherited the family passion for hunting, to his ruin, and of Macris, who nursed the child Dionysus.
"Aristaios" ("the best") is an epithet rather than a name
For some men to call Zeus and holy Apollo.
Agreus and Nomios, and for others Aristaios (Pindar)
Aristaeus in Ceos
Aristaeus' presence in Ceos, attested in the fourth and third centuries BCE, was attributed to a Delphic prophecy that counselled Aristaeus to sail to Ceos, where he would be greatly honored. He found the islanders suffering from sickness under the stifling and baneful effects of the Dog-Star Sirius at its first appearance before the sun's rising, in early July. In the foundation legend of a specifically Cean weather-magic ritual, Aristaeus was credited with the double sacrifice that countered the deadly effects of the Dog-Star, a sacrifice at dawn to Zeus Ikmaios, "Rain-making Zeus" at a mountaintop altar following a pre-dawn chthonic sacrifice to Sirius, the Dog-Star, at its first annual appearance, which brought the annual relief of the cooling Etesian winds.
In a development that offended more immediate causality for the myth, Aristaeus discerned that the Ceans' troubles arose from murderers hiding in their midst, the killers of Icarius in fact. When the miscreants were found out and executed, and a shrine erected to Zeus Ikmaios, the great god was propitiated and decreed that henceforth the Etesian wind should blow and cool all the Aegean for forty days from the baleful rising of Sirius. But the Ceans continued to propitiate the Dog-Star, just before its rising, just to be sure.. Aristaeus appears on Cean coins.
Then Aristaeus, on his civilizing mission, visited Arcadia, where the winged male figure who appears on ivory tablets in the sanctuary of Ortheia as the consort of the goddess has been identified as Aristaeus by L. Marangou.
Aristaeus settled for a time in the Vale of Tempe. By the time of Virgil's Georgics, the myth has Aristaeus chasing Eurydice when she was bitten by a serpent and died.
Aristaeus and the bees
Soon Aristaeus' bees sickened and began to die. He went to the fountain Arethusa and was advised to establish altars, sacrifice cattle and leave their carcasses. From the carcasses, new swarms of bees rose (see Bugonia).
"Aristaeus'" as a name
In later times, Aristaios was a familiar Greek name, borne by several archons of Athens and attested in inscriptions.
