If you are minded to observe the Charioteer and the Charioteer’s stars, and rumour has reached you of the Goat herself and the Kids, who have often looked down on men being tossed upon the heaving sea, [160] you will find the Charioteer lying large to the left of the Twins, while opposite Helice circles his head at that extremity. Fastened to his left shoulder is the sacred Goat, who is said to have tendered her breast to Zeus: the interpreters of Zeus call her the Olenian Goat. [165] Now he is large and brilliant, but her Kids there on the Charioteer’s wrist shine faintly.

Near the feet of the Charioteer look for the horned Bull crouching. This constellation is very recognisable, so clearly defined is its head: one needs no other [170] sign to identify the ox’s head, so well do the stars themselves model both sides of it as they go round. Their name is also very popular: the Hyades are not just nameless. They are set out all along the Bull’s face; the point of its left horn [175] and the right foot o f the adjacent Charioteer are occupied by a single star, and they are pinned together as they go. But the Bull is always ahead o f the Charioteer in sinking to the horizon, though it rises simultaneously.

Hyginus, Astronomica

In Latin we call him "auriga" — Erichthonius by name, as Eratosthenes shows. Jupiter seeing that he first among men yoked horses in four-horse chariots, admired the genius of a man who could rival the invention of Sol, who first among the gods made use of the quadriga. Erichthonius first invented the four-horse chariot, as we said before, and also first established sacrifices to Minerva, and a temple on the citadel of the Athenians. Euripides gives the following account of his birth. Vulcan, inflamed by Minerva's beauty, begged her to marry him, but was refused. She hid herself in the place called Hephaestius, on account of the love of Vulcan. They say that Vulcan, following her there, tried to force her, and when, full of passion he tried to embrace her, he was repulsed, and some of his seed fell to the ground. Minerva overcome by shame, with her foot spread dust over it. From this the snake Erichthonius was born, who derives his name from the earth and their struggle. Minerva is said to have hidden him, like a cult-object, in a chest. She brought the chest to the daughters of Erechtheus and gave it to them to guard, forbidding them to open it. But man is by nature so curious, that the oftener he is forbidden to do something, the more he desired to do it. So the girls opened the chest and saw the snake. As a result they were driven mad by Minerva, and threw themselves from the Acropolis. But the snake fled to the shield of Minerva, and was reared by her.

Others have said that Erichthonius merely had snake-legs, and in his youth established the Panathenaic Games for Minerva, himself competing in the four-horse chariot race. In return for these deeds he was placed among the constellations.

Some too, who have written about the stars, have said that the Charioteer was an Argive by birth, named Orsilochus, who first invented the four-horse chariot, and for his invention gained a place among the stars.

Others identified him as the son of Mercury and Clytie, Myrtilus by name, the charioteer of Oinomaus. After his death, the manner of which is common knowledge, his father is said to have put his form in the sky.

On his left shoulder (the goat) Capra stands, and in his left hand the Kids seem to be placed. They tell this story about him. A certain Olenus, son of Vulcan, had two daughters, the nymphs Aex and Helice, who were nurses of Jove. Others have said that certain cities were named from them — Olenus in Aulis, Helice in the Peloponnesus, and Aex in Haemonia — about which Homer writes in the second book of the Iliad. But Parmeniscus say that a certain Melisseus was king in Crete, and to his daughters Jove was brought to nurse. Since they did not have milk, they furnished him a she-goat, Amalthea by name, who is said to have reared him. She often bore twin kids, and at the very time that Jove was brought to her to nurse, had borne a pair. And so because of the kindness of the mother, the kids, too were placed among the constellations. Cleostratus of Tenedos is said to have first pointed out these kids among the stars.

But Musaeus says Jove was nursed by Themis and the nymph Amalthea, to whom he was given by Ops, his mother. Now Amalthea had as a pet a certain goat which is said to have nursed Jove.

Some have called Aex the daughter of Sol, who surpassed many in beauty of body, but in contrast to this beauty, had a most horrible face. Terrified by it, the Titans begged Terra to hide her body, and Terra is said to have hidden her in a cave in the island of Crete. Later she became nurse of Jove, as we have said before. But when Jupiter, confident in his youth, was preparing for war against the Titans, oracular reply was given to him that if he wished to win, he should carry on the war protected with the skin of a goat, aigos, and the head of the Gorgon. The Greeks call this the aegis. When this was done, as we have shown above, Jupiter, overcoming the Titans, gained possession of the kingdom. Covering the remaining bones of the goat with a skin, he gave life to them and memorialised them, picturing them with stars. Afterwards he gave to Minerva the aegis with which he had been protected when he won.

Euhemerus says that a certain Aex was the wife of Pan. When she was embraced by Jove she bore a son whom she called son of Pan. So the child was called Aegipan, and Jove, Aegiochus. Since he was very fond of him, he placed in memory the form of a goat among the stars. (Mary Ward 1960)
