Final answer:
Early synagogues occasionally featured paintings, stucco, seats and desks, and religious art such as glass mosque lamps and carpets.
Step-by-step explanation:
The artistic mediums that would occasionally appear in early synagogues include paintings, stucco, seats and desks, and religious art such as glass mosque lamps and carpets. The synagogue paintings found in Damascus are the earliest surviving biblical narrative cycle and were mistaken for a Greek temple at first. Stucco was a prominent material used in architectural structures regardless of religious affiliation, and seats and desks were important features for reading and studying prayers and religious doctrine.
