|Villa Giulia, Rome|
In architectural academia there has persisted controversy over whether or not the Tuscan should really be regarded as a distinct order or if it is nothing more than a stripped down or simpler version of the Doric order. A similar argument is made regarding the Composite or so-called Roman order, that has conversely been claimed as just a more elaborate version of the Corinthian order. Certainly all of the Roman orders share a familial resemblance and of course are referential to the Greek orders from which they were developed. However, I'll take the position here that there are in fact enough differences to justify a separate classification of the Tuscan order beginning with a brief historical overview.
The Tuscan order is ostensibly referential to the architecture of the Etruscan people who dominated the Italic peninsula until Rome was finally able to overcome them in the 4th century B.C. Temples presented the highest expression of Etruscan architectural refinement. As temple foundations were built in stone we have a very good understanding of how they were organised in plan. The precise composition of the elevations is less clear although some idea can be gleaned from pictorial depictions such as found on ostraca (decorated potshards), sarcophagi as well as frescoes.

A few Etruscan tectonic characteristics were definitely distinct from the Greeks and would be adopted by the Romans for all of their architectural orders. Whereas the single cella or inner sanctum of a typical Greek temple was surrounded by a stylobate (series of steps) and peripteral colonnade (the columns being present along the entire perimeter of the building), the Etruscans lifted their temples upon a podium with a stair leading to the entrances of three cellae. Columns were only used at this entrance, placed in a double row underneath a large portico whilst the cellae walls extended to the exterior. Timber members for the entablature allowed for greater intercolumniation (spacing of the columns) than was feasible for the stone architecture of Greece.

A System of Proportion
|Elevation of the Five Orders of Architecture|
Claude Perrault, 1683
Granted, even in theory there was a wide range of interpretation available and more so in practise. The various authors were not always in agreement. In arguably the first major treatise of the Renaissance containing engraved plates, Sebastiano Serlio presents a very squat Tuscan order whose base diameter to column height ratio was 1:6. Vincenzo Scamozzi and Claude Perrault would subsequently present comparatively slender Tuscan orders at a ratio of 1:7½. Likewise a wide variety is seen in proportions of entablatures and pedestals in relation to the module. What remained consistent was that as the orders progressed they would become proportionally more attenuated with the Tuscan order always being the most solid amongst them.

An Anthropomorphic Model
|Palazzo Davia Bargellini, Bologna|
Rather than seeking anatomical precision, these myths and comparisons continue to serve as entertaining and helpful memory aids regarding the character and proportions of the various orders. Architects of the Renaissance, the Baroque, all the way into the Beaux Artes period picked up and expanded upon these anthropomorphic associations. What interpretation remained for the Tuscan? Rough and tumble for sure. That of a Titan, an Atlas who carries the burden of the building quite literally on his back!
Elements and Enrichment
|Radcliffe Camera, Oxford|
Although the Tuscan often gets berated as being a 'made up' order or just a stripped Doric, it really has its own distinct character and bears more consideration and study, particularly as it continues to be the most commonly specified of the Classical orders in residential architecture today.
