Ἐλατήρ

[Meaning] a flat pastry like a cake; hence its name [e)lath/r], from being driven [e)lau/nesqai] with the hands into flatness. Or a hollow loaf of bread, in which they used to put the bean soup and bring it to the altars.¹
"You will know Alkman, an exceptional player of the Laconian lyre, whom the number of the nine Muses includes."²
There are also flattish [cakes] [lagarw/deis] [sc. so named] from lagaro/n ["hollow"]. And [sc. they are called] pe/lanoi in Euripides.³
Also [sc. attested is the genitive] e)lath=ros, [meaning] a kind of unleavened cake. But Euripides [refers to] pepta/ ["cookies"].⁴
