KV15 is known to have been opened in antiquity, as there are 59 examples of Greek and Latin graffiti on the walls. Richard Pococke investigated it as early as 1738, but it was not until the arrival of Howard Carter in 1903–04 that the tomb was properly cleared.[1] After Howard Carter began to excavate the nearby tomb of Tutankhamun (KV62) in 1922, KV15 was used by his assistants Alfred Lucas and Arthur Mace as a makeshift laboratory for the cleaning and restoration of KV62's artifacts before their transport to the Cairo Museum.[3]
