The content cloaks issues in architectural issues with philosophy, religion and other contextual references which leads to some practitioners’ contention that the treatise is “religious mumbo‐jumbo” while others attempt to employ it as a technical construction manual. This paper submits that the treatise is primarily about architectural theory and practice and its focus is design processes for different building types set out in the form of textual guidelines detailing the stages involved in the generation of the built form. This finds resonance in parametric design viewed as a set of instructions establishing relationship between objects controlled by variables which renders the treatise relevant to contemporary architecture in general and computation design process in particular. The utility of the treatise is enhanced in conservation efforts, especially reconstruction of ruined historical buildings, and post‐colonial scholarship in indigenous knowledge systems. Also, by premising correlation with contemporary processes in computation design, this paper informs their historical location and contributes towards their place as integral to design systems. It is premised that by going “back” in history in the form of an ancient treatise, the future, envisioned as parametric design, is informed. Keywords: Parametric design process, historical treatise on architecture in India, Samranganasutradhara. 1. Introduction Ancient treatises on architecture in India form a knowledge system which is reflected in historical buildings in a complex manner. Most practitioners refer to treatises in a peripheral and technical manner while acknowledging their latent influence on historical monuments like temples and palaces. This paper suggests that the treatise is in the realm of theory and practice and submits that their relevance to contemporary architecture is significant. A compilation of earlier texts from inter‐disciplinary sources, Indian treatises are written in regional languages whose authorship is ambiguous, given the paucity of scholarship on ancient India. From the Mayamatam to the Samranganasutradhara, each treatise builds on the knowledge base of earlier texts and spans across the sub‐continent in origin and language including Pali and regional Sanskrit. 262 A. Janus, R. Contractor, Y. Patel and P. McPherson Content includes philosophy and science along with theory, practice and construction processes in architecture. As most scholars are from fields outside architecture, the full import of its architectural merit is lost which, when combined with factors including translation and cultural distance, lowers the intelligibility of the text for architects. The tone is conversational as most text is in the form of instructions, stages of architectural process interspersed with philosophical insights. The censorial genre discourages the casual reader and the uninitiated from using the text irresponsibly. Favourable and unfavorable attributes of the built environment associated with implications on the user/client/owner have been analyzed by this study and it is premised that they are based on aesthetical principles of form and space and user experience in the built environment. Fraught with cultural and gender biases, social hierarchy and contextual issues, the study removes this encrustation to arrive at the architectural core of the writing.Sacred associations’ cloaks content rendering it esoteric and obscurantist to the casual reader, therefore, all superfluous implications of religion require strict sieving such that architectural content is not sacrificed at the cost of religious bias. This results in some practitioners’ contentions that the treatise is “religious mumbo‐jumbo” while others use it as a technical construction manual and attempt to apply the text literally without conducting an abstraction exercise to arrive at principles which may be relevant to theory/practice/construction. By conducting a grounded theory research methodology, data from the text has been interpreted architecturally and formulated into a theoretical construct with a particular focus on design process. The treatise selected as the case study in this paper is the Samranganasutradhara, attributed to the polymath King Bhoja ‐ which dilutes its religious intent‐ around the 10th century, locating it in pre‐colonial India. Narrated by the celestial architect Vishwakarma to his children, it raises questions pertaining to all aspects of architecture which are answered in subsequent chapters. The core reading is a Hindi translation of the original treatise in Sanskrit (Jugnu 2011) which minimizes loss of meaning in translation. After interpreting the Hindi and Sanskrit text for architectural implications, an English interpretive translation is rendered comprehensible to the modern scholar by associative correlation with contemporary paradigms. Finally, this study focuses on the design process aspect as this is relevant to theory and practice and forms the majority of the content. During successive readings, it became apparent that the process set out in the text is analogous to generative and computation process. Simultaneously, a critical analysis of generative, computation and parametric design processes is conducted to explore associative layers and discover correlation with the treatise. िशालैकशालिशालचयोगत: II 25.05 II षटशालमंजायतेवेभेदातुषोडशI In this manner, combination of bi‐hall, uni‐hall and tri‐hall dwellings Hexa‐cell dwelling are assembled and these are 16 in number 2. Parametric Design Process for Architecture and the Treatise The focus of this study is the instructions to generate built forms in the treatise – dwellings, palaces and temples‐ which resemble text algorithms in a generative parametric design system is employed as a tool to design with (Leach 2009), which is at variance with its popular connotation as a style and a representation technology. Parametric is referred to as a set of instructions to generate a form utilizing algorithms which are an explicit statement of a sequence of operations needed to perform a task. The logic and structure of the design process is the focus of parametric design and the end product is an “Back” to the Future 263 infinite set of solutions which, according to Eisenman, are made finite by the individual intellect of the architect. समशीषदातोयथाशोभयथािच I ेभागसम: काय: कलशूिलकावधे: II 30.18 II Roof/skyline (of the palace) should be made as aesthetically appropriate and accordingly to the personal inclination of the architect Finial and molding should be created in proportion to the parts of the site Here, the focus is on requirements of the process instead of its product which is generated from the textual instructions is in the form of a three dimensional object – parameters and schema. Parametric design process is an iterative activity which involves continuous generation of a design artefact, evaluation of its ability to satisfy requirements efficiently, which if unacceptable to the architect is followed by a new iteration which involves either a radical reformulation of design concept and/or a modification of design parameters. The linguistic parametric design lists a finite set of instructions, analogous to cooking recipes and furniture assembly instructions, where the individual stage needs to be explicit, detailed and adaptable. “In a field made quadrangular, divide into four parts” (56.45.1) assumes that the architect interprets this as all sides of the quadrangle are divided into four parts based on the premise of three dimensional spatial construct. “The wall should on all sides’ measure one part, and the remainder should be the sanctum” (56.45.2) signifies the demarcation of void by the solid while “With a projection of two parts, a width of three parts, and adorned by pillars” (56.46.2) highlights that the adornment of the pillars is left to the designer. Flexibility and adaptability is built into the system as only ratio and proportion and not absolute numbers are employed in the generation of the form. The following text from the treatise gives guidelines on the design process to generate the form for a temple. चतुरीकृ तेेेचतुभागिवविजते I भािगकासवतोिभि: शेषंगभगृहंभवेत् II56.45 II तात: पुन: कायभागयिविनगत: I िवारेणिभागाीव: भूिषत: II 46 II पीठोेघभागेनभवेािभािगका I भागाधवारंपपादेनादवरका II 47 II सपादांतुरोभागाशखरेृतः I िगुणेनचसूेणपकोशंसमािलखेत् II 56.48 II In a field made quadrangular, divide into four parts The wall should on all sides’ measure one part, and the remainder should be the sanctum Moreover, in front of that, one should build a pillared porch With a projection of two parts, a width of three parts, and adorned by pillars According to the parts of the height of the base, the wall should be two parts The antarapatra should be half a part and the varandika should be one part The height of the shikhara is known to be four parts and a quarter With a cord of three guna, one should draw the profile as a lotus petal 264 A.

Stages In conventional design process, a solution is generated, evaluated against criteria and modified in reaction to the evaluation. On the other hand, in generative design, several options are generated and the designer chooses the most appropriate one.
