ABSTRACT This article studies the remains of the ways of building after the Fa11 of the Roman Empire and discusses, in particular, the size of the eufrasian basilique from the methodological point of view, the modular rythm, the proportion and numerical symbolism. Key words: ways of building, size, eufrasian basilique, modular rithm, proportion, numeri- cal symbolism. Fecha de recepción: diciembre 1993. Faculty of Architecture p.0.b. 154, Zoisova 5. 61000 LJUBLJANA (Slovenia) The principles of the antique architectural composition survived the fall of the Roman empire. A good example for the survival is the architecture of buildings in the complex of the Eufrasian basilica in Parentium, or PoreE in Croatian or Parenzo in Italia. The dimensional analysis of buildings in the complex of the Eufrasian Basilica reveals that the standard Roman pes, the Byzantine pous and the Venetian piede were used as modules. Between the Sh and 20ih century, when the Basilica of Eufrasius and its surrounding buildings were erected, a number of successive governments imposed their standard systems of measures. The Roman dimensions gave way to the Byzantine units of length to be followed by the Venetian measures. The French metre and the Wiennese Fuss during the Napoleonic and the successive Austrian occupation left no trace. But inspite of the different systems of measure- ment, the antique compositional principles remained in use. In this paper, we will discuss dimensions of the Basilica Eufrasiana buildings from the point of view of the - metrology, - modular rhythm, - proportion, and the - symbolism of numbers (gematria). An order is a precondition of a composition'. Without order, there is chaos. In architecture, the order is created with the modular rhythm2. A module is usually a unit in a standard system of linear measures3. Modular sizes of the Roman building components are small4 multiples of various dimensional units. Compositions of components are consequently sums and multiples of various standard units. A length of a building, e.g., was determined by a Roman architect as a multiple of a Roman standard dimensional unit. It was easy to transform such a length into sums and multiples of smaller standard sizes and hence the building's articulation. Vitruvius emphasized this principle by telling architects to respect diligently the ratio of symmetries, i.e., the ratio of modules: Aedium compositio constat ex symmetria, cuius rationem architecti diligentissime tenere debent5. The word symmetria in the Vitruvian context is not understood any more. Cesare Cesariano is aware in his edition of Vitruvius that the word will not be generally comprehensible: La qual Symmetria mai alcuni saperano bene intendere: ne operare si diligentemente etpromptamente non saperano le regule Arithmetice6 Follows the Cesariano's commentary on symmetria: Consta de symmetrie: cioe di proportionale commensuratione 1 If from any craft you subtract the elements of numbering, measuring and weighing, the remainder will be almost negligible (Plato, Philebus, 55 d-e). We can deduce from this conclusion that orderly arrangement of compo- nents results in a composition, which has different qualitative properties than a disorderly agglomeration of the same components. 2 The primitive order in architecture is the modular rhythm. Building parts combine into an architectural composition when the relations between their dimensions are expressible with ratios of small whole numbers (KU- RENT, T.: La legge fondamentale della composizione modulare, Quaderni di studio, Facolta di architectura, Politech- nico di Torino, 1968). 3 A module is a common denominator of architectural dimensions. The units of length in the old systems of lineal measures are used as modules in historical architectures (KURENT, T.: I1 principio modulare. -Belfagor (Firenze), XXX, 2, 1975). 4 KURENT, T.: The Basic Law of Modular Composition. -The Modular Quarterly, Winter 1964-65. 5 VITRUVIUS: De architectura, 111, Y ,  1.  6 Cesare Cesariano (Como 1521), Vitruvius De Architectura, Wilhelm Fink Verlag, Muenchen, 1969. 1:1 PRIMA Q OUADRUGON 1 : 1,828 I* DUAL DIAGON m 1 - 4 - 9  - 22-53-128 - * -a-*- 1 - 2 - 5  - 1 2 - 2 9 - 7 0  -+ 2f i - l=11828  ...

The definition of symmetria by Cetus Faventinus is similar: Graeci modulorum mensuras symmetrian appelaverunt7. The understanding of historical architecture is not possible without metrologys. In the Eufrasian buildings, the Roman pes, the Byzantine pous and the piede Veneziano determine the modular rhythm. The present bishop's residence is a palace, built in the 6th century on the Roman foundations. Its dimensions can be measured with the Roman foot, or pes, 295,7 mm. long. Basilica itself, the baptistry, the memorial chapel and the atrium in front of the entrance to the sanctuary were designed in the 308,OO mm. long Byzantine foot, or pous. After the retreat of Byzantines, new buildings were conceived in the Venetian foot, or 347,30 mm. long piede veneziano. Among them, the oldest is the 15Ih century sacristy, which is a link between the Basilica proper and the memorial chapel. The church-tower was built in the 16th century. The two chapels were added to the southern side of basilica in the 19th century. The foot, used as module in the Eufrasian buildings, was not constant in size, but the modular principle remained unchanged. 7 HUGH PLOMMER: Vitruvius and Later Roman Manuals, Cambridge, University Press, 1973.

Vitru- vius relates that mensurarum rationes, quae in omnibus operibus videntur necessariae esse, ex corporis membris collegerunt, uti digitum, palmun, pedem, cubitum (Vitruvius, De architectura, 111, I, 5). Pour relever et comprendre les monuments grecs, c'est avec le pied grec qu'il les faut mesurer (VIOLLET-LE-DUC: Dictionnaire Raisonne, VIII, Symmetrie). Une analyse correcte du procede de composition d'un monument architectural du passe, soit dans son ensamble, so,it en son detail, n'est pas possible, si I'on ne connait pas le systeme de mesures, sur lequel il est base (ZLOKOVIC M,: Antropomorfni sistemi mera U arhitekturi. -Zbornik zaitite spomenika kulture IV-V, Beograd, 1953-1954). Metrology mirrors the history of civilisation (KURENT, T.: Merski sistemi v arhitekturi na Slovenskem.

ILLUSTRATION 3. Buildings composing the Eufrasius' basilica complex in Pore&Parentium were erected between the Yh and the 20"' Century. In that period, the Roman, the Byzantine, the Venetian and$nally the metric measurement were taking place. The proportioning scheme, regulating the Eufrasian buildings9 in the Roman, and Byzantine period, is the eight-pointed star, called octagramI0. The Sh century baptistry is a regular octogon in plan. The bishopric and the Basilica Sanctae Agnese, built not far away in the 6th century on Roman foundations in the rhythm of pes, are designed as distorted octagrams". The ratio 1 :2 is the predominant proportion in the Byzantine era. The clear width and length of the Basilica, e.g., are 60 and 120 podes. The width of 60 podes is twice larger than the axial width of the central nave. In the same proportion 1.:2 are the 29 ft height of the roof around atrium and the 58 ft distance between Basilica and baptistry. Also, the 45 ft height of the octagonal baptistry and the 90 ft distance between campanile and Basilica are in the ratio 1:2. The Venetian proportions is also simple. The ground plan of the belltower is a square, 20 piedi wide. The square and the double square are both in the family of octagram's proportions. In both cases the preferred dimension is either repeated or doubled. The simplicity of proportioning with squares is due to the preference of symbolic numbers. The preferred modular dimensions were chosen by the architect because of their gematrical messages. All numbers in the Basilica's dimensions have their symbolic meaning. The length of Basilica, e.g., is 496 modules of 4 dactyls. The length without apsida is 888 modules of 2 dactyls. The width and height of basilica are 127 modules of 8 dactyls and 432 modules of 2 dactyls, respectively. In the Venetian period, number 496 reappears in the height of the church- tower, the cross on the top included. Numbers 888,496,432, 127, 120,90,60, 30 ... have their symbolic, or better, their gematric meaning. GematriaI2 is a Hebrew term for the translation of words into numbers and vice versa. The Hebrew and Greek letters are simultaneously symbols for numbers. Later, the Latin, Cyrillic, Glagolitic and the Arab gematrical cryptography developed. In this paper, we are interested only in the Greek and Latin gematric codes.

With the distortion of rectangular plan, more preferred numbers were built into dimensions.

Preferred numbers, used as modular multiples in the dimensional composition of the Basilica Eufrasiana. says that a cypher can have the same gematrical meaning as a 2-, 3-, 5-, 7- times larger or smaller number. This is understandable, since 1 foot equals 2 semes, or 3 trientes or 4 palmi or 12 unciae or 16 digiti. Besides, l palmipes is equal to 5 palmi and 1 cubitus longus to 7 palmi. The multiple meaning of a number is still echoed in the Christian dogma, that the Holy Trinity, the Father, the Son and the Holy Ghost, are but one God. This numerical ambiguity of the old world ended when Arabs introduced their (Indian) numerals in Europe. Moslems believe that Allah is only one and unique: Allah Wahed AhadI3. In other words, numbers 3, 30, 3000, 120, 6, 240, are gematrically synonymous. According to the Greek gematria, the most holy name of Jesus has the value of 888: 13 1 1 2  Sura. El Ihlas.

The number 888 and its synonyms are common in dimensions of churches. The Saint Stephan cathedral in Wienna, e.g., is 222 Wiener Fuesse wide. The cistercian basilica at Stic'na, Slovenia, is 222 pedes, or 888 palmi, long. LAHM, K.: Siebenunddreisig. Die Neuentdeckte Schluesselzahl des Stephansdom. Das Reich, Juni 1943.

Number 432.000 in the Icelanding Edda, e.g., is a product of numbers 540 (doors) and 800 (soldiers passing through). See chapter Grimnismal in the book: WAGNER, F.: Les poemes mythologiques de I'Edda, Facute de Philosophie et Lettres, Liege, Librairie E. Droz, Paris, 1930. According to Berosus, the reigning of Mesopotamian kings before the Deluge lasted 432.000 years long. See: VON GUTSCHMID, A.: Zu den Fragmenten des Berosus und Ktesias, Reinische Museum, VIII, 1853. According to Arybhata, the Hindu Macha-Yuga is 4,320.000 stellar years. See: Aryabhata, Sanscrit Edition, Leiden, Holland, 1874. Our number is also known in the Greek world. The Platonic nuptial year equals 63 = 53+43+33= 216 ordinary years. See: SHORLEY, P,: Plato: Republic, The Loeb Classical Library, VIII, 546 b-d. Vitruvius writes about number 216 in his Book V, 3-4. 18 PLATO: Critias, The Loeb Classical Library, William Heinemann, Ltd, London.

Besides, in the number 300 is written the message: SERENISSIMA REPUBLICA VE- NEZIA. Gematrically built-in messages are considered a sort of mysticism. But if Sheldrake's theory of morphogenetic fieldsI9 is valid, we might assume that gematric ideas influence even those who have never heard about gematria and even do not understand the language. Conclusion. Metrology, the modular principle, proportion, the preferred numbers and gema- tria are not to be disregarded in the research of historical architectures.
