Tracta (dough)

[3] Laganon/laganum was at different periods an unleavened bread, a pancake, or later, perhaps a sort of pasta.

Vehling's translation of Apicius glosses it as "a piece of pastry, a round bread or roll in this case, stale, best suited for this purpose".

[6] It is also mentioned in Cato the Elder's recipe for placenta cake, layered with cheese.

[7] Athenaeus's Deipnosophistae mentions a kind of cake called καπυρίδια, "known as τράκτα", which uses a bread dough, but is baked differently.

[8] Some writers connect it to modern Italian lasagna,[9] of which it is the etymon,[10] but most authors deny that it was pasta.
