SINGLE-YEAR ¹⁴C DATING OF THE LAKE-FORTRESS AT ĀRAIŠI, LATVIA

ABSTRACT Single-year 14 C sampling of a spruce log from the timber platform on which Āraiši lake-fortress was built dates this exactly, by synchronization with AD 774/5 Miyake event. Dendrochronological synchronisms between dated and other timbers provide annual precision for construction site. The felling date obtained, 835, is 50–60 years later than that proposed previously (Meadows Zunde 2014) basis wiggle-match ages decadal blocks IntCal13 calibration curve (Reimer et al. 2013), although same data favor in 830s when wiggle-matched to IntCal20 2020). Our results appear confirm doubts expressed Philippsen (2022) about values ca. 825-835.
