Description
Monument Type: Standing stone
SMR No.: ME031-033014-
A pillar-shaped stone on the northern side of the central mound of the Forradh, this monument is popularly identified as the Lia Fáil (1.57m high, girth 1.58m at ground level and 1.23m near the top), known as The Stone of Destiny. This identifiation is not certain. It was reputedly moved here from its original position near the Mound of the Hostages in 1824 in commemoration of those who fell during the Battle of Tara in 1798. It is lightly engraved with a cross and the letters R.I.P., below which may be the very faint traces of a ringed cross.
The stone is phallus-shaped and such a stone features in an account of the inauguration ceremony of the kings of Tara described in the 8th-century text De Shíl Chonairi Móir ('On the descendants of Conaire Mór'), according to which the prospective king Conaire Mór mates symbolically with the sovereignty goddess, by riding his chariot between the magical stones Blocc and Bluigne, which part only for the rightful king, and over the Lia Fáil, which screeches out against the chariot axle.

3D Capture Method: Close range Scanning
3D Capture Description: The Next Engine 3D Laser Scanner was utilised to generate resolution models of surfaces with small scale detail. The Next Engine uses MultiStripe Laser Triangulation (MLT) technology.
- Source - Twin arrays of four, Class 1M, 10 mW solid state lasers with custom optics 650 nm l.
- Sensor - Twin 3.0 Megapixel CMOS image sensors.
- Photo Surface - Optically synchronous 7-color surface capture for precision-locked geometry correlation.
- Photo Lighting Built-in spatially diverse white-light illuminators with triphosphor, wide color gamut.
- Object Size - No preset limit. Objects larger than field can be assembled with supplied software.
- Field Size - 5.1" x 3.8" (Macro) and 13.5" x 10.1" (Wide). HD PRO Extended Mode 22.5" x 16.75".
- Resolution - 3D point density on target surface is 400 DPI in Macro Mode and 150 DPI in Wide Mode. Texture Density - 400 DPI on target surfaces is 400 DPI in Macro Mode and 150 DPI in Wide Mode.
- Dimensional Accuracy±0.005" in Macro Mode and ±0.015" in Wide Mode.
Post-processing is done in Geomagic Studio 2012 software: individual scans are edited, aligned, before a final surface is generated using global registration, fusion, and a small objects filter algorithm.. For dissemination purposes a 3D pdf of the model is generated using Geomagic Studio 2012.
