In palaestris peristylia quadrata sive oblonga ita sint facienda, uti duorum stadiorum habeant ambulationis circuitionem, quod Graeci vocant diaulon, ex quibus tres porticus simplices disponantur, quarta quae ad meridianas regiones est conversa, duplex, uti, cum tempestates ventosae sint, non possit aspergo in interiorem partem pervenire.
Square or oblong cloisters are to be made with a walk round them of two furlongs (this walk the Greeks call diaulos). Three of the sides are to be single colonnades; the fourth which has a south aspect is to be double, so that when rain is accompanied by gales, the drops may not reach the inside.
