Pompeii archaeological park head Massimo Osanna told Italian news agency ANSA that the villa belonged to a high-ranking military officer, perhaps a general, during ancient Roman times.
Osanna was quoted on Dec. 23 as saying the remains of two or three other horses were also discovered.
The villa's terraces had views of the Bay of Naples and Capri island. The area was previously excavated, during the early 1900s, but later re-buried.
The volcanic eruption of Mount Vesuvius destroyed flourishing Pompeii, near present-day Naples, in 79 A.D.
Osanna says suffocating volcanic ash or boiling vapors killed the horses. He hopes the villa eventually will be open for public visits.
