A Lady and Her Two Children

From a report by dendrochronologist Ian Tyers, “The Tree-Ring Analysis of Twenty-Three Panel Paintings from the Yale Center for British Art, New Haven,” November 2011

This panel is ca. 911 mm high, ca. 684 mm wide, and constructed from 3 vertical oak boards ca. 8 mm thick, labeled for the purposes of this report A–C from the left. The possible onset of sapwood on the upper left corner of board C means that a felling date range may be applied to the panel.…

These boards were fairly tangential sections, and had fast grown and distorted grain. Partial sequences were obtained from the upper edges of all boards. The sequences from boards B & C were found to cross-match each other, and were probably derived from the same tree. The composite series of these boards was found to date against eastern English reference data. The short board A series was not successfully dated.

The last ring in the upper edge of board C was dated to 1600, this ring marking the onset of sapwood. Adding the minimum and maximum expected number of sapwood rings, appropriate for English material, this suggests that this board was derived from a tree felled between 1610 and 1646.
