Araeostyle
Araeostyle (Latin: ''araeostylos,'' from grc, ἀραιόστυλος, from αραιος, "weak" or "widely spaced", and grc, στυλος, "column") is one of five categories of intercolumniation (the spacing between the columns of a colonnade) described by the Roman architect Vitruvius. Of all the ancient architectural categories, the araeostyle has the widest spacing of columns, with an intercolumniation equal to four column diameters. Because of the wide span, timber rather than stone In geology, rock (or stone) is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its Chemical compound, chemical composition, and the way in which it is formed. Rocks ... architraves were used.

Intercolumniation
In architecture, intercolumniation is the proportional spacing between columns in a colonnade, often expressed as a multiple of the column diameter as measured at the bottom of the shaft. In Classical, Renaissance, and Baroque architecture, intercolumniation was determined by a system described by the first-century BC Roman architect Vitruvius (Vitruvius, ''De architectura'', iii.3.3-10). Vitruvius named five systems of intercolumniation (Pycnostyle, Systyle, Eustyle, Diastyle, and Araeostyle), and warned that when columns are placed three column-diameters or more apart, stone architraves break. According to Vitruvius, the Hellenistic architect Hermogenes (ca. 200 BC) formulated these proportions ("''symmetriae''") and perfected the Eustyle arrangement, which has an enlarged bay in the
