This is a black, white and greyscale plan. There is a key across the bottom. No scale or compass is provided.
To the left is the River Tiber. The river meanders through the plan from top to bottom. From the centre at the top the river curves gently towards the right and then back in a large sweeping curve towards the left. In the lower half of the plan it curves towards the right again before bending back and exiting at the bottom. An island can be seen in the centre of the lower bend. Four sets of short narrow parallel lines form gaps in the river in the lower half of the plan. One of these goes through the island. These represent bridges across the river.
Contour lines are shown on both sides of the river. To the left these are restricted to the bottom left-hand corner. A larger set of contour lines indicating several hills are shown down the length of the right-hand side.
The space formed by the large central bend of the River Tiber is labelled CAMPUS MARTIUS. Between this space and the contours on the far right there is a series of numbered shapes. An un-numbered building is labelled VILLA OF LUCULLUS. This can be seen parallel to the contours at the top right.
Two parallel lines labelled VIA FLAMINIA begin at the top of the plan a little way to the right of the river. They run at an angle down towards the right. When they reach the contours they follow them. The letters A to D can be seen alongside the upper part.
The key names a series of 19 structures located in a vertical strip between the river and the contours. They are grouped within a roughly diamond shape with the lower numbers towards the top, the middle numbers in the centre and the higher numbers towards the bottom. The structures are:
1 Mausoleum of Augustus as directional guide.
2 Ustrinum Domus Augustae
3 Horologium Augusti
4 Ara Pacis
5 Ara Providentia (?)
6 Aqua Virgo
7 Porticus Vipsania
9 Saepta Julia
10 Agrippan Pantheon
11 Stagnum and Euripus
12 Baths of Agrippa
13 Temple of Mars
14 Theatre of Pompey
15 Theatre of Balbus
16 Porticus Octaviae
17 Theatre of Marcellus
18 Temple of Juno Moneta
19 Temple of Jupiter Optimus Maximus
There is a key for the letters A, B, C and D which lie along the upper part of VIA FLAMINIA.
A is located at the top of the plan on the VIA FLAMINIA. The key indicates A is the view between Mausoleum and Ustrinum to the upper façade of Saepta Julia. The point of an elongated triangle filled with diagonal lines from top right to bottom left begins at A and spreads out as it proceeds down. Near the top it runs between 1 Mausoleum of Augustus and 2 Ustrinum Domus Augustae. It then goes through the left-hand side of 3 Horologium Augusti. At the lower end it covers the width of 9 Saepta Julia.
B is located just below A on the VIA FLAMINIA.The key indicates B is the view between Mausoleum and Ustrinum broadening to include north elevation of Agrippan Pantheon. The point of an elongated triangle filled with diagonal lines from top left to bottom right begins at B and spreads out as it proceeds down. It runs between 1 Mausoleum of Augustus and 2 Ustrinum Domus Augustae. It then goes through the left-hand side of 3 Horologium Augusti. At the lower end it covers the left half of 9 Saepta Julia and the right half of 10 Agrippan Pantheon.
A hatched area where the diagonal fill of both triangles meet is shared by both A and B. This covers the left-hand side of 9 Saepta Julia.
C is located further down the VIA FLAMINIA at the lower right–hand edge of 2 Ustrinum Domus Augustae. A line of black dots runs diagonally from C to the centre of 9 Saepta Julia.
D is situated on the VIA FLAMINIA between 4 Ara Pacis and 5 Ara Providentia (?). A hatched triangle begins at D. Its bottom right corner is in the centre of 7 Porticus Vipsania. The left-hand corner almost reaches the top right-hand corner of 8 Divorum.
Curved lines of dots link several of the features on the plan. One dotted line begins at the river and almost touches the lower edge of 1 Mausoleum of Augustus crosses VIA FLAMINIA towards a gap in the contours where it doubles back down to the centre of 9 Saepta Julia. A second short line of dots links the lower right-hand corner of 8 Divorum with 13 Temple of Mars and then to VIA FLAMINIA.
A little further down VIA FLAMINIA a third line of dots links it with 15 Theatre of Balbus, 16 Porticus Octaviae, 17 Theatre of Marcellus and then down to the lower bend of the River Tiber.
