Chryseïs is asteroid #202 and also known as A879 RA. Chryseïs’ orbit is characterized by a semi-major axis of 3.97 Astronomical Units, an eccentricity of 0.10, a period of revolution of 1 968 days, and an inclination of 8.8 degrees. Chryseïs measures 86 km in diameter. Chryseïs was discovered by the German-American university teacher and astronomer Christian Heinrich Friedrich Peters at the Litchfield Observatory of the Hamilton College, Clinton, New York, USA.

Chryseïs is named after the Trojan woman Chrysēís (Χρυσηίς). She is the daughter of Chrýsēs (Χρύσης) and this also is the meaning of her name. Later writer gave her the name Astynome (Ἀστυνόμη), a description of her appearance, and made her a relative of Hippodameia (Ἱπποδάμεια), who was known as Brīsēís (Βρῑσηΐς), which means the daughter of Brísēs (Βρίσης). Chrýsēs (Χρύσης) was a priest of Apollon Sminthios in Chryse (Χρύση), now Gülpınar, Ayvacık County, Çanakkale Province, Turkey. Chryse (Χρύση) means The Golden and was known only for the Smintheion, the temple of Apollon Sminthios. Its ruins still exist. Apollon Sminthios is the god of mice.

The Greek warrior Achilleus (Ἀχιλλεύς), after whom the asteroid Achilles is named, abducted Chrysēís (Χρυσηίς) and Brīsēís (Βρῑσηΐς) as a prey of war. He kept Brīsēís (Βρῑσηΐς) for himself and gave Chrysēís (Χρυσηίς) to his military commander Agamémnōn (Ἀγαμέμνων). The priest Chrýsēs (Χρύσης) saw his daughter in the camp of the Greek warriors and tried to buy her back. But Agamémnōn (Ἀγαμέμνων) rejected every offer. Chrýsēs (Χρύσης) prayed to his god and Apollon Sminthios sent a plague epidemic to the camp of the Greek warriors. This made Achilleus (Ἀχιλλεύς) foment the Greek warriors until Agamémnōn (Ἀγαμέμνων) returned Chrysēís (Χρυσηίς) to Troy. But Agamémnōn (Ἀγαμέμνων), who lost his prey of war this way, took Brīsēís (Βρῑσηΐς) from Achilleus (Ἀχιλλεύς) as a compensation. I mentioned Brīsēís (Βρῑσηΐς), after whom the asteroid #655 or Briseïs is named, already in my article on the asteroid Agamemnon. Achilleus (Ἀχιλλεύς) lost his prey of war this way and hence refused to do anything for the Greek campaign anymore. He was in a strike.

Agamémnōn (Ἀγαμέμνων) did nothing to obtain Chrysēís (Χρυσηίς), yet he got angered because he had to return her. Economists call it compensation for opportunity costs if a company asks for a compensation for an option, which the company did never realize. But Chryseïs should rather represent a person, who receives big support because an epidemic was caused for the sake of ending the slavery of Chrysēís (Χρυσηίς) as soon as it began. This although enslaving Chrysēís (Χρυσηίς) as a prey of war was seen as rightful because Brīsēís (Βρῑσηΐς) stayed captive and nobody even thought of returning any other captive for the sake of ending the plague epidemic. Chrysēís (Χρυσηίς) was only freed because of her connections. So Chryseïs indicates support by a religious institution and also by the own family.
