For the extensive changes made in the earlier part of the first century B.C. we have the evidence of an inscription, which had been cast aside and was found in one of the smaller rooms. It reads, _C. Uulius C. f., P. Aninius C. f., II v. i. d., Laconicum et destrictarium faciund. et porticus et palaestr[am] reficiunda locarunt ex d[ecurionum] d[ecreto] ex ea pequnia quod eos e lege in ludos aut in monumento consumere oportuit faciun[da] coerarunt eidemque probaru[nt]_. The form of the letters and the spelling point to the time of Sulla as the period in which the inscription was cut. The syntax is confused, but the meaning is clear: a Laconicum and _destrictarium_ were built, the colonnade and palæstra repaired, by the duumvirs Gaius Ulius and Publius Aninius, in accordance with a vote of the city council; and they furnished the means for this work in fulfilment of their obligation, incurred by the acceptance of the duumviral office, to spend a certain sum upon either games or buildings. The destrictarium--a room for removing dirt and oil with the strigil after gymnastic exercises--is easily identified (D), as are also the palaestra and colonnade; but in our survey of the baths, we have found no separate chamber to which the term Laconicum could properly be applied. In order to arrive at a solution of the difficulty, we must note the successive steps by which, as shown by an examination of the remains of the masonry, the heating arrangements were extended and improved. At first, in the Baths as originally constructed, there were neither hollow walls nor hollow floors. The heating was done by means of braziers; and there were niches or lockers in the walls of the caldariums and tepidariums similar to those now found in the dressing rooms, but in double rows, the upper niches being larger, the lower smaller. Later, a hollow floor was built in the men's caldarium. Later still, this room was provided with hollow walls, which were extended to the crown of the ceilings and the lunettes, the tepidarium being still heated with braziers. Finally, a hollow floor and hollow walls were constructed at the same time in the men's tepidarium, but the hot air chamber was not carried up into the ceiling or the lunettes. A similar transformation was gradually accomplished in the women's apartments; but owing, it would seem, to a desire for greater warmth in the tepidarium, the hot air chamber here, as in the caldarium, was extended to the lunettes and the ceiling.
