Threshold
Description
A. Karivieri & R. Forsell
The threshold is made out of three lava blocks. The northern one has been cracked. The threshold stands 13 cm high above the sidewalk of Via del Vesuvio. In the middle of the threshold there is a cavity running from north to south in its entire length. The cavity is 4 cm wide and 3 cm deep, except for the northernmost 62 cm where it is deeper, 7 cm. The threshold is cut to a 3 cm lower level in the north, 70 cm long on its eastern side and 10 cm on its western side. 7 cm from the northern doorpost there is a square cutting, 8x8 cm, for the door socket. By the southern doorpost there is a rectangular cutting 4x6 cm.
Observation: The threshold is flaking and is has cracked in many places due to age and ware.
