In the statue 'Grave Naiskos of an Enthroned Woman with an Attendant' at the Oracle Of Delphi, there is a woman looking into an object resembling a laptop. It's too thin and looks like a jewelry box, so studies are going towards a kind of device that is a laptop. The woman in the statue is looking right in the middle of it, which depicts that there is a screen that she is staring into.
There is still no confirmation that the object is actually a laptop computer from the olden times, but historians are looking into the matter.
It depicts a woman lounging in an armchair reaching out to the lid of a shallow chest which is brought by a servant girl.
The speculations included - a laptop, a mythical Pandora's box, a jewelry box and a wax tablet.
Since it is too thin to be a jewelry box, the only solution other than the laptop the historians can come up with is a Wax Tablet.
It was used as a traditional writing board with a stylus like object to write on it.
Although, the Oracle of Delphi was a sacred area for priests to connect with the Gods and beings of higher intelligence, they could have got the instructions or powers to build a device like a laptop.
Wax tablets were depicted in paintings and Greek art very often so that sounds like a more reasonable theory.
A wax tablet requires a stylus to be written with so it is a necessary accessory.
So it's highly unlikely for the object to be a wax tablet as well.
There are many conclusions over the statue and since the woman is touching the screen in a particular way, it could also be a touchscreen device.
The Greek were advanced and highly intelligent people, so they could be using high-tech devices that we don't know about as yet.
