It is convenient here to give a list of the May warning stars found by Mr. Penrose in Greece, as it shows that the same stars were observed for the same purpose. +-------------------------------+------------+--------+--------+----- | | | Decl. | Day. |Year. +-------------------------------+------------+--------+--------+----- | | | | |B.C. |Archaic temple of Minerva |Pleiades (R)| +7° 50′|April 20|2020 |Hiero of Epidaurus, Asclepieion| „ (R)| +9 15 | „ 28|1275 |Hecatompedon | „ (R)| +9 58 | „ 26|1150 |Older Erechtheum |Antares (S)|-14 31 | „ 29|1070 |Temple of Bacchus |Pleiades (R)|+10 35 | „ 29|1030 |Corinth |Antares (S)|-16 0 | May 6| 770 |Aegina | „ (S)|-16 45 | „ 7| 630 +-------------------------------+------------+--------+--------+----- The warning stars at Athens were the Pleiades for temples facing the east, and Antares for temples using the western horizon. _August warnings._--Sunrise at the August festival was heralded by the rising of Arcturus, which, as we have seen, was also used as a clock-star. The alignments and dates given in the Arcturus table therefore hold good for August. At the Hurlers, where the hill over which Arcturus was observed fell away abruptly, we find Sirius supplanting Arcturus as the warning star for August in 1690 B.C. _November warnings._--So far I have discovered no evidence that any star was employed to herald the November sun. There may be two reasons for this. In the first place the November festival “Halloween” took place at sun_set_ and the sun itself could be watched, no heralding star being necessary.
