Title:   Mycenaean Well (S/1,2-13/20,14/1)
Category:   Well
Description:   Mycenaean Well (S/1,2-13/20,14/1). Underneath the NE Room of the Library of Pantainos, along its S side, as a cutting in bedrock containing reddish fill with bits of green bedrock. The feature is rectangular in shape, and measured ca. 1.00m NS by 0.65m EW at the bottom.
The function of the well is unclear. The depth of the feature , in particular in comparison with wells in the same area, would indicate that the shaft was unlikely to have served as a well, unless the water table in this area changed dramatically between ca. 1500 and ca. 400 B.C.
The presence of Roman pottery and the absence of pottery from intervening periods (5th-4th c. B.C.) seems to indicate that the shaft of S 13:2 may not have been filled to the top originally (or the fill settled over centuries), and had been covered in some way, not to be rediscovered until the early Roman period.
The location of the well immediately beside a wall of the library main room, as well as the coincidence of the top edge of the well with the bottom level of the library Main Room wall, would suggest that the shaft was cut into during preparations for the construction of the library, which also removed any structural remains that may have been associated with the use phases of the Classical wells.
[per Jan, some of the info for this lists new grid as ,T1/1 instead of the correct , 14/1. Make the correction]
