The time has come to elect a new HAD Vice- Brad Schaefer, Yale University Chair and two members of the HAD Committee.

Lunar ethnographic evidence exists that anypre- 1900 orientations can be easily found at many sites culture displayed any interest in lunar and Moon goddesses are common, so on the standstills.

But this carries One person raised a separate-but-related no implication that the Zuni used, cared about, question, asking "What is wrong with 'the or recognized the standstill phenomenon. existence of the alignment itself as evidence?" He then points to many cases where (4) Hawluns' original historical evidence for "historical" data is unreliable by itself and Stonehenge standstill alignmentswas a passage where archaeological data is adequate by itself. fiom Diodorus Siculus concerning It was speculated that the motive for raising (presumably) Britain, in which the Moon and this good point is a response to the occasional the nineteen-year Metonic period are prejudice where classical historians ignore all mentioned among a jumble oftopics [Hawluns, nontextual data.

And one textual error (the Metonic cycle is not the everyone agrees that the more types of standstill cycle). But the record must be confirming information available, the more heavily "deciphered," and other interpretations confident the result. Hence, the case for lunar are reasonable, so this connection was alignments would be substantially stronger if characterized as "inconclusive." we knew that many (or even a few) cultures were interested in standstills, fiom written or (5) Hawkins also relates a story [Mindsteps of oral data. the Cosmos, pg. 89-90] about a (modem?) farmer near a stone circle who connects the Several responses to the side-question ("Is a circles to something the Moon does every 19 lunar standstill alignment good enough by years.

Diodorus tradition with all its weaknesses yet Various problems were noted that led people to with two more millennia of separation. suspect that an alignment alone was not enough in general. The first problem is that damage or rebuilding while many have alignments to them; it is might shift the orientation.

The example question in the first place, so as to evaluate given was that a cairn near a stone circle sites by test D. cannot readily be distinguished as fkom the Bronze Age or fkom a medieval farmer. From the replies, I don't think that our community is in disagreement. So let me be so The thrd problem is that "the artifacts rarely brash as to try to briefly summarize what I speak for themselves and usually have to be learned: Five ethnographclhistoric examples evaluated," which is to place the ideas in the of interest in standstills were advanced, but all context of the culture. No example was given, taken together are too weak to be considered but I readily recall the myriad interpretations useful. No reliable written or oral report is for Stonehenge when the stones are allowed to known of any culture anywhere before 1900 speak for themselves. having any interest in lunar standstills. This is in sharp contrast to the bountiful reports of The fourth and greatest problem is that no case solar alignments of various types, so that we of lunar standstill alignments has been shown can realize that few (if any) cultures have any to be statistically significant. The example interest in the standstill phenomenon.
