The name Cydippe (Κυδίππη) is attributed to four individuals in Greek mythology.
Cydippe was the mother of Cleobis and Biton. Cydippe, a priestess of Hera, was on her way to a festival in the goddess' honor. The oxen which were to pull her cart were overdue and her sons, Biton and Cleobis pulled the cart the entire way (45 stadia; 8 km). Cydippe was impressed with their devotion to her and asked Hera to give her children the best gift a god could give a person. Hera had the two brothers drop dead instantaneously as the best thing she could give them was for them to die at their moment of highest devotion. This is Herodotus's account (Histories 1.31) of the story and it comes couched as advice from Solon the Athenian to Croesus as to who the most blessed people in history are. The most often used quotation from this episode is (roughly translated) "call no man blessed until he is dead."
Herodotus, the original source for this story, does not state the name of the mother of Cleobis and Biton. The first mention of their mother's actual name can be found in Plutarch, Frag. 133 (= Stobaeus 4.52.43) "
ἔτι δὲ Κλέοβις καὶ Βίτων, Κυδίππης τῆς μητρὸς αὐτῶν ..." Plutarch (first century CE) is the earliest source for her name that is now available to us. Surely much intervening literature regarding Cydippe the priestess of Hera has been lost, since Plutarch was writing about 500 years after Herodotus first told the story.
Cydippe or Cyrbia was the daughter of Hegetoria and Ochimus. She married Ochimus' brother, Cercaphus, who inherited the island. According to an alternate version, Ochimus engaged Cydippe to Ocridion but Cercaphus loved her and kidnapped her. He did not return until Ochimus was old.
Cydippe was the name of one of the Nereids, daughters of Nereus and Doris.
Cydippe was an Athenian girl who was obliged to marry Acontius.
