The T-shaped furnace or oven is already a familiar feature of Romano-British archaeology. Whether among the huts and pits of Woodcuts, the more substantial dwellings of Silchester and Caerwent, or the farmsteads of the rural areas, this type of oven occurs with such frequency that its place in Romano-British economic life must have been an important one.
It is not proposed to discuss here at length the function of these furnaces. This problem was resolved beyond any measure of doubt when the Romano-British villa was excavated at Hambleden, Bucks., in 1912, and Professor Gowland, in an Appendix to the excavators' report, stated that ‘In my opinion they are flues of drying floors which have been used for drying harvested grain.’ The evidence from sites elsewhere (as at Caerwent and at King's Worthy, Hants, at both of which sites charred wheat was recovered from the flues of the ovens) has provided strong corroboration of Professor Gowland's hypothesis, and it is only surprising to find that the unmistakable corn-drying ovens of Woodcuts village were still classed as ‘hypocausts’ in the 1931 edition of Professor Collingwood's Archaeology of Roman Britain.
The main interest of the Hambleden discoveries lies, however, in the great variety of types of ovens excavated, for in all no less than fourteen specimens were unearthed, ranging from the simple and basic T-shaped type to structures of considerable elaboration. Such a variety of types on one single site demands some explanation, and it is not inconceivable that the Hambleden villa was something in the nature of an experimental station.
