Simply put, there's not a lot of documentary evidence related to teleturgics from the first two centuries. And many sources that do mention something about worship are written by highly educated philosophers (e.g. Justin Martyr or Clement of Alexandria). This poses a historiographical problem, I think, because educated people of that time looked down on the use of incense in general. Hellenistic philosophers had been ranting against its use -- and against religious sculpture and painting -- for generations upon generations. This is especially true of the schools in Alexandria and Rome. Thus, any educated person would naturally be inclined to dismiss or condemn incense. To do otherwise would be plain ignorant and very plebian. IIRC, Clement more or less says so himself. He was a consummately urbane gentleman, fully in tune with the best philosophy and science of his time.
