![Arculf's sketch of the Holy Sepulchre, included in Adomnán's De Locis Sanctis ("On the Sacred Places"). The captions are likely Adomnán's. The sketch posted here is from a 9th-century copy of De Locis Sanctis, currently at the Austrian National Library in Vienna, Codex 458, f4v.
The sketch map is quite accurate, lending credibility to Arculf's pilgrimage account.
Then there's this, from De Locis Sanctis IX:
"Between that Basilica of Golgotha [round structure on the Left, here Arculf is referring to the Basilica built by Constantine around 336 AD over the tomb provided by Joseph of Arimathea for Jesus] and the Martyrium [three Crosses on the Right] there is a recess ["exedra" in Latin] in which is the Cup of the Lord [or Holy Grail]...the cup is silver, holding the measure of a Gaulish quart [Arculf and Adomnán apparently are referring to a "sextarius" - a Latin word for 1/6 of a Roman gallon or just over 1 modern pint] and has two little handles placed on it, one on each side."](https://pbs.twimg.com/media/HVg1yfDXgAANVTc.jpg?name=small&format=webp)
