Italian term or phrase: in cavaliera
Title: prospettiva

In epoca tardoantica, a causa del doppio impulso del misticismo cristiano e della condanna neoplatonica dell'illusionismo, si semplifica la rappresentazione dello spazio: viene adottato il metodo della "dissociazione prospettica", per cui ogni oggetto può essere visto prospetticamente, entro una sua nicchia di spazio prospettico, ma manca completamente un criterio unificatore.
Questa tendenza si accentua nell'arte bizantina, caratterizzata da un senso di spazio indefinito: gli oggetti sono rappresentati ortogonalmente, in prospettiva inversa o in cavaliera.

I've ascertained that cavaliera comes from the mathematician, Bonaventura Cavalieri and have a basic idea of what they are talking about on his Wikipedia page but I am still not sure exaclty how to translate it.

English translation:cavalier projection
Explanation:
In cavalier projection (sometimes cavalier perspective or high view point) a point of the object is represented by three coordinates, x, y and z. On the drawing, it is represented by only two coordinates, x" and y". On the flat drawing, two axes, x and z on the figure, are perpendicular and the length on these axes are drawn with a 1:1 scale; it is thus similar to the dimetric projections, although it is not an orthographic projection, as the third axis, here y, is drawn in diagonal, making an arbitrary angle with the x" axis, usually 30 or 45°. The length of the third axis is not scaled.

It is very easy to draw, especially with pen and paper. It is thus often used when a figure must be drawn by hand, e.g. on a black board (lesson, oral examination).

The representation was initially used for military fortifications. In French, the « cavalier » (literally rider, horseman, see Cavalry) is an artificial hill behind the walls that allows to see the enemy above the walls. The cavalier perspective was the way the things were seen from this high point. Some also explain the name by the fact that it was the way a rider could see a small object on the ground from his horseback.

Asker: Yes Marie - I had already looked at that page and was tempted to go for it but felt a bit out of my depth since maths is not my strong point. Hence sought some Proz help! From art suddenly I was up to my eyes in Maths!!
