In the Middle Ages, the settlement was known as Vesaina (Βέσαινα), which in the corrupted form Desiani (Δέσιανη) continued until the early 20th century. Vesaina is first attested in the 11th century, as a bishopric and in an inscription found in Agia of a certain Euthymios, ""protospatharios" of Vesaina". A letter of Michael Psellos mentions the bishopric as being very poor.
