This pool was already known to Parker and Vincent, who entered it from below. Parker and Vincent named it the “Round Chamber” (Vincent, Underground Jerusalem, pl. 2), although it is not a chamber because it has no ceiling. We encountered the “Round Chamber” from above. To preserve a snippet of history, we may also record the following: After Parker and Vincent entered Channel II and from there entered their “Round Chamber,” they sealed the entrance. In 1970 two young archaeology students who were at the time assistants to Professor Nahman Avigad dared to break through the blocking and tour the channel but did not record their visit. They were Amihai Mazar, now the distinguished excavator of Beth-Shean and Tel Rehov, and Ronny Reich. Only a decade later did Yigal Shiloh enter it again.
