"They are small terracotta tubes with one pointed end. Put one into the other, they formed interlocking, snake-like tiles. Rows of these so-called fictile tubes were used by Roman builders to relieve the weight of vaulting,"
That makes it sound like they were structural but I don't have the slightest idea how they were used. They seem too small to have any value in a building.
