There were several types of vase in ancient Athens for perfumed oils. The aryballos and alabastra were small, and their round bases prevented them from standing on their own. They required a support or were suspended from a cord. The plemochoe has a flat base but on fifth-century vases is often shown being carried by a woman. The mouth is specially profiled to minimize spilling.
