facts, from <strong>the</strong> most deeply buried to those closest to <strong>the</strong> surface, it is possible<br />
to develop a “relative” chronology, with <strong>the</strong> oldest materials at <strong>the</strong> bottom<br />
and <strong>the</strong> youngest at <strong>the</strong> surface.<br />
By 1950, Willard Libby had developed a technique for “absolute” dating,<br />
which enabled <strong>the</strong> calendar year in which an organic material died to be established,<br />
within an error range based on <strong>the</strong> accuracy <strong>of</strong> <strong>the</strong> technique. Yet<br />
radiocarbon dating <strong>of</strong> archaeological deposits in Jamaica has never been a priority.<br />
As a result, <strong>the</strong>re are very few absolute dates for any <strong>of</strong> <strong>the</strong> sites. Instead,<br />
<strong>the</strong> tendency has been to cross-date material remains on <strong>the</strong> basis <strong>of</strong> similarities<br />
to previously dated artefact styles. Cross-dating is accomplished by<br />
matching artefacts from one site with those from o<strong>the</strong>r sites that have been<br />
radiocarbon-dated.<br />
Over <strong>the</strong> past decade, scientists have recognized potential sources <strong>of</strong> error<br />
in radiocarbon dates. <strong>The</strong> method measures concentrations <strong>of</strong> carbon-14, an<br />
isotope <strong>of</strong> carbon-12 whose abundance in <strong>the</strong> atmosphere has varied through<br />
time. In addition, different living tissues contain different concentrations <strong>of</strong><br />
C 14 . Various correction factors are now applied to give corrected and calibrated<br />
radiocarbon dates, which are given as a mean date ± an error range (for example,<br />
one <strong>of</strong> <strong>the</strong> dates for <strong>the</strong> Sweetwater site at Paradise Park is calibrated AD<br />
1430 ± 70).<br />
<strong>The</strong> calibration <strong>of</strong> radiocarbon dates indicates that <strong>the</strong> age ranges given for<br />
<strong>Jamaican</strong> cultures may need revision. It should be remembered that radiocarbon<br />
dates are not really “absolute”; <strong>the</strong>y come with an error range and are<br />
based on statistical probabilities. When atmospheric fluctuations in C 14 are<br />
considered, <strong>the</strong> dates for <strong>Jamaican</strong> cultures are about a century younger than<br />
previous estimates, so some <strong>of</strong> <strong>the</strong> dates may need to be adjusted. For example,<br />
<strong>the</strong> AD 650 date, which is used for <strong>the</strong> beginning <strong>of</strong> <strong>the</strong> Little River style,<br />
should be revised to around AD 750. In addition, <strong>the</strong> early dates for <strong>the</strong> White<br />
Marl site (Silverberg, Vanderwal and Wing 1972) – AD 877 ± 95 and AD 934<br />
± 95 – would calibrate to around AD 1000–1020. <strong>The</strong>se calibrated dates are<br />
more consistent with o<strong>the</strong>r dates from <strong>the</strong> site, which range from AD 1150 to<br />
AD 1350. We mention <strong>the</strong>se modifications because it is <strong>of</strong>ten assumed that<br />
radiocarbon dating provides absolute dates for material, and such is not <strong>the</strong><br />
case: radiocarbon dates indicate only a range <strong>of</strong> possibilities for <strong>the</strong> timing <strong>of</strong><br />
past events (see Davis 1988).<br />
Research in Jamaica is more characteristic <strong>of</strong> <strong>the</strong> culture-historical<br />
approach, in which <strong>the</strong> sequence <strong>of</strong> Redware to White Marl is viewed as an<br />
adequate rendering <strong>of</strong> <strong>the</strong> cultural sequence. Marion De Wolf in 1933 conducted<br />
excavations at three sites in <strong>the</strong> parish <strong>of</strong> St Ann: Little River, Little<br />
Nigger Ground Hill (Retreat) and Windsor. Twenty years later she highlighted<br />
her findings in a report on <strong>the</strong>se excavations entitled “Excavations in
