From Dr. Keefe's journal: "Visited Tower of the Winds, which the signs call Bath-House of the Winds (are they trying to combine its 2 different functions of baptistery + horologion?). It's not at all sure it was a baptistery. There are 2 large doors to the west and north, and 1 small window at lower level and 1 at higher level -- wooden conical roof. Sort of frieze about halfway up on inside, from what I could see trying to poke my head thru grill. Oddly, there's a little door on the southwest that leads to a semicircular room, so plan actually looks like [sketch of octagon with semicurcular bulge on one side]"
