[The sun is called ἥλιος ] from being gathered together [ἀολλίζεσθαι ] in the daytime. And at Athens there was a lawcourt [called] Heliaia, from the gathering of men.[1] But the sun [is called ἥλιος ] from warming [ἀλεαίνειν ] which means heating and dispersing. But some say [it is so called] from the breath coming from the mouth to the fingers, which is called blowing [αὔειν ] and sighing [ἄζειν ][2] by imitation of the sound of the heating of the mouth. Empedocles [writes]: "it travels around to leap [over] the great heaven ."[3]
