Castor, the supposed disciple of Chiron, was in reality the same as Chiron; being a sacred tower, a Chironian edifice, which served both for a temple and Pharos. As these buildings for the most part stood on strands of the sea, and promontories; Castor was esteemed in consequence of it a tutelary Deity of that element. The name seems to be a compound of Ca-Astor, the temple or place of Astor; who was rendered at different times Asterius, Asterion, and Astarte. Ca-Astor was by the Greeks abbreviated to Castor; which in its original sense I should imagine betokened a fire-tower: but the Greeks in this instance, as well as in innumerable others, have mistaken the place and temple for the Deity, to whom it was consecrated. The whole history of Castor and Pollux, the two Dioscuri, is very strange and inconsistent. Sometimes they are described as two mortals of Lacedæmon, who were guilty of violence and rapine, and were slain for their wickedness. At other times they are represented as the two principal Deities; and styled Dii Magni, Dii Maximi, Dii Potentes, Cabeiri. Mention is made by Pausanias of the great regard paid to them, and particularly by the Cephalenses. [370]Μεγαλους γαρ σφας ὁι ταυτῃ Θεους ονομαζουσιν. _The people there style them by way of eminence the Great Gods_. There are altars extant, which are inscribed [371]CASTORI ET POLLUCI DIIS MAGNIS. In [372]Gruter is a Greek inscription to the same purport. Γαιος Γαιου Αχαρνευς Ἱερευς γενομενος Θεων Μεγαλων Διοσκορων Καβειρων. But though Castor was enshrined, as a God, he was properly a Tarchon, such as I have before described; and had all the requisites which are to be found in such buildings. They were the great repositories of treasure; which people there entrusted, as to places of great security. The temple of Castor vas particularly famous on this account, as we may learn from Juvenal: [373]Æratâ multus in arcâ Fiscus, et ad vigilem ponendi Castora nummi.
