foe, and welcome as an ally,(1259) was authorized by the ambiguity of his name. 5. On the other hand, the title AGYIEUS had a single signification.(1260) This appellation of Apollo was peculiar to the Dorians,(1261) and consequently of great antiquity at Delphi;(1262) from which place, however, it was brought over to Athens at a very early period, and indeed partly at the command of an oracle.(1263) His statue was erected in court-yards, and before the doors of houses; that is, at the boundary of private and public property, in order to admit the god as a tutelary deity, and to avert evil. The symbol or image of the god was most simple, being a conical block of stone. The ancients knew not whether to consider it as an altar or statue.(1264) The worship consisted of a constant succession of trifling services and marks of adoration.(1265) Frankincense was burnt before the pillar;(1266) it was bedecked with wreaths of myrtle, garlands, &c. This was sufficient to remind, and at the same time to assure, the ancient Dorians of the protecting presence of their deity. The Athenians represented their Hermes in a similar manner. This god, although fundamentally distinct from Apollo, was invested by them with the same offices: thus the statues of both gods were placed, as protecting powers, in front of the houses: both gods were supposed to confer blessings on those who either entered or left the house: both were represented by simple columnar statues. With Apollo, however, this protection was rather of a spiritual and inward nature: while the phallic form, which always distinguished the Hermæ of Athens, shows that this god was considered to afford, by increasing the fruitfulness of the fields and cattle, and generally all the products of nature, a more external and physical assistance. 6. To these titles may perhaps be added the name of APOLLO itself. That we must search for its etymology in the Greek language alone, and that it could have been derived from no other source, is evident from the preceding investigations. In the first place, then, we cannot derive it from the sun, ΑϜΕΛΙΟΣ,(1267) since the digamma is never changed into Π. The derivation from ΟΛΩ we have already rejected, as being founded on a partial and occasional attribute of the god.(1268) On the other hand, we may observe that the ancient Doric Æolian form of the name was not Ἀπόλλων but Ἀπέλλων,(1269) which also obtained amongst the ancient Latins,(1270) and from which the Macedonian and Delphian month _Apellæus_ evidently derived its name. Now if this is admitted to be the original form, Ἀπέλλων simply means the _averter_ or _defender_,(1271) and belongs to the same class as Ἀλεξίκακος, Ἀποτροπαῖος, and other names mentioned above.
