Note 109 — HISTORY (continued 2)
Reading edition
The testimony of maps is not wholly either in favour of a triangular gallows, or of the site as indicated by the maps of Mackay and Rocque. In a few the gallows is shown as consisting of three pieces. In one map such a gallows is shown at some distance to the west of Edgeware Road. But the maps are small and unimportant with one exception—John Seller’s map of the county of Middlesex, 1710 and 1742. In these the gallows of three pieces is placed just within the angle formed by the junction of the roads. But the evidence that at these dates, 1710-42, the gallows was triangular, and that it stood in the centre of the open space is too clear to be upset by the evidence of this map.
