The return of royal burials to Thebes after the end of the Amarna Period marks a change to the layout of royal burials, with the intermediate 'jogged axis' gradually giving way to the 'straight axis' of later dynasties. In the Western Valley, there is a tomb commencement that is thought to have been started for Akhenaten, but it is no more than a gateway and a series of steps. The tomb of Ay, Tutankhamun's successor is close by. It is likely that this tomb was started for Tutankhamun (its decoration is of a similar style), but later usurped for Ay's burial. This would mean that KV62 may have been Ay's original tomb, which would explain the smaller size and unusual layout for a royal tomb.
