Final answer:
Historically, various cultures have had different methods and structures for transporting cremated remains, such as the Romans with their cinerary urns. In poetry, the urn serves as a symbolic image for a tomb and a metaphorical container for meaning, as seen in Thomas Gray's works.
Step-by-step explanation:
The structure used to transport an urn of cremated remains in a ceremonial fashion to a final resting place does not have a specific term universally applied to it; however, in a historical context, various cultures have had ceremonial practices for transporting the ashes of the deceased. The Romans, for instance, used cinerary urns to store cremated remains, which were sometimes transported in processions analogous to funerary parades. This practice reflected a deep respect for deceased family members and ancestors, known as mos maiorum or 'the way of the ancestors.'
In poetry, the urn is symbolically used to denote a resting place for the dead or metaphorically as a container for artistic meaning. Thomas Gray's 'Elegy Written in a Country Churchyard' refers to storied urns as symbols capable of containing stories and meanings.
Differences in funerary customs, such as those between Etruscans and Romans, highlight cultural changes over time, with the Romans opting for cremation over burial. The Romans' use of ceramic urns and the public aspect of their funeral rites are significant historical examples of ancestral veneration and the transport of cremated remains.
