The Ramesses IX Tomb-plan Ostracon is a buff-white limestone ostracon inscribed with a layout of Ramesses IX's tomb, KV6-Valley of the Kings, from the 20th Dynasty, c 1100 BC.
It is inscribed on a sherd of approximate dimensions: 0.66m L (2/3 meter) by 0.2m W, and was found within his KV6 tomb.
The 'blueprint-like' "tomb-plan" is not a draft plan of the tomb construction, but is a post-construction record.
Notes in Hieratic name rooms, with dimensions.
The composition of straight lines, (from a straightedge/device) use mostly 90 degree angles, but the design layout also conforms to the linear shape of the sherd, (thus requiring deviations from the 90 degree right angles).
As a linear sherd, the ostracon is broken into 4 contiguous pieces.
As a dagger-shape, (non-rectangular), this is an atypical usage for ostraca, but the intention was probably durability, its resistance to decay and alteration, (the inks mostly).
