[4] "θεοὶ θνητοὶ," "ἄνθρωποι ἀθάνατοι." It is most curious to find this so academic question dragged into the hard light of day and subjected to the scrutiny of so prosaic a person as the Roman tax-collector. Under the Roman Empire all lands in Greece belonging to the immortal gods were exempted from tribute, and the Roman tax-collector refused to recognise as immortal gods any deities who had once been men. The confusion arising from such questions offered an admirable target to Lucian for his keenest shafts of ridicule. [5] "Deutsche Mythologie," article on the Condition of the Gods.

CHAPTER IX DRUIDISM Although Irish literature is full of allusions to the druids it is extremely difficult to know with any exactness what they were. They are mentioned from the earliest times. The pre-Milesian races, the Nemedians and Fomorians, had their druids, who worked mutual spells against each other. The Tuatha De Danann had innumerable druids amongst them, who used magic. The invading Milesians had three druids with them in their ships, Amergin the poet and two others. In fact, druids are mentioned in connection with all early Irish fiction and history, from the first colonising of Ireland down to the time of the saints. It seems very doubtful, however, whether there existed in Ireland as definitely established an order of druids as in Britain and on the Continent.[1] They are frequently mentioned in Irish literature as ambassadors, spokesmen, teachers, and tutors. Kings were sometimes druids, so were poets. It is a word which seems to me to have been, perhaps from the first, used with great laxity and great latitude. The druids, so far as we can ascertain, do not seem to be connected with any positive rites or worship; still less do they appear to have been a regular priesthood, and there is not a shadow of evidence to connect them with any special worship as that of the sun or of fire. In the oldest saga-cycle the druid appears as a man of the highest rank and related to kings. King Conor's father was according to some--probably the oldest--accounts a druid; so was Finn mac Cool's grandfather. Before the coming of St. Patrick there certainly existed images, or, as they are called by the ancient authorities, "idols" in Ireland, at which or to which sacrifice used to be offered, probably with a view to propitiating the earth-gods, possibly the Tuatha De Danann, and securing good harvests and abundant kine. From sacrificial rites spring, almost of necessity, a sacrificial caste, and this caste--the druids--had arrived at a high state of organisation in Gaul and Britain when observed by Cæsar, and did not hesitate to sacrifice whole hecatombs of human beings. "They think," said Cæsar, "that unless a man's life is rendered up for a man's life, the will of the immortal God cannot be satisfied, and they have sacrifices of this kind as a national institution."
