Second temple period ritual baths adjacent to agricultural installations: The archaeological evidence in light of the halakhic sources

Ritual baths (miqwa'ot) built adjacent to winepresses and olive-presses have been unearthed at about twenty sites dating to the Second Temple period, most of them in Judea and the environs of Jerusalem. While much has been written in recent years on the form and function of ancient ritual baths in general, little scholarly attention has been paid to miqwa'ot found in agricultural contexts. The presence of these miqwa'ot suggests that the ritual purity of the wine and olive oil processed in these installations was of particular importance. The fact that these ritual baths were situated adjacent to winepresses and olive-presses suggests that agricultural labourers made use of these miqwa'ot immediately prior to commencing work in these installations, a practice which accords with the Pharisaic concept of tend yom. These finds thus provide rare archaeological evidence for the observance of ritual purity laws based on the Pharisaic system of halakhah.
