(ὁ/τὸ σκύφος; h o/tò skýphos). Tall but stable drinking cup with two handles usually attached horizontally, originally a rustic wooden beaker (Ath. 11,498-500). The synonym κοτύλη/kotýlē is generally used as a term for a cup of no fixed typology. The capacity of a skyphos was between a kotyle  and a chous . As a wine vessel, it is attested more frequently for komasts than for symposiasts.
