14 clusters of 105 years, we are well-aware of the “sometimes-deceptive effects of
aggregation” (E.R. Tufte, Visual explanations: images and quantities, evidence and narrative
[1997] 35) – increments much smaller could cause possibly-misleading multiplication
of the names, whereas increments much larger might falsely suggest synchronizations.
7 Four encyclopedia lemmata generate multiple entries in this index, either because they
represent multiple authors or works: Apollo ̄nios Biblas and Son (two narrow); Aristio ̄n
(Mech.) (one narrow, one wide); and Z ̄ıg (two akme ̄, one narrow), or else because two
disjoint date-ranges are suggested: Komerios (two wide); see also Hermolaos (Geog.) and
Ze ̄nario ̄n, for which two disjoint date-ranges are suggested, with the later one being
after our terminus.
8 Finally, two kinds of entries are not indexed here at all:
a eight on schools or collections, which extend over many centuries, and represent no
single work: Arabic Translations; Aristotelian Corpus in Pahlavi; Babylonian
Astronomy; Demotic Texts; Hellenizing School (Armenian); Hippokratic Corpus in
Pahlavi; Pahlavi translations; and “Papyri” (the entry introducing all the individual
papyrological entries).
b four non-existent people: Sextus of Apollo ̄nia, Salimachus, Silimachus, and
So ̄sandros (Vet.); moreover, Askle ̄piade ̄s Titiensis and Auidianus should perhaps be
likewise omitted.All entries with “narrow” date-ranges are plotted above; the smaller fluctuations may not be
significant, but the large rise (500 to 330 ) and the high level (through ca 100 )
surely are, as is also the precipitous fall after Hadrian (ca 140 ). (The “late-Hellenistic”
dip, of the 2nd c. , may be significant.) Below we also plot all the entries with “wide”
