The crowsteps motif in Nabataean architecture: insights into its meaning and use

Nabataeans, in constructing their tombs, added many symbols and geometrical forms, plants and animals. Crowsteps, as a geometrical form, are the most common among these symbols. This study investigates the use of the crowsteps motif found frequently on the facades of Nabataean tombs. The primary focus is to replace models of typological explanation for the introduction of crowsteps into the Nabataean rock‐cut facades. The study begins with tracing the origin of the crowsteps motif and the way it was adopted by the Nabataeans to become one of the most significant features in the making of Nabataean architectural vocabularies. It then provides a theoretical framework for explaining the use and meaning of the crowsteps in Nabataean architecture. Thematic analysis of related literature and existing architectural remains allows us to suggest that crowsteps served both sacred and secular purposes. Sacredly, crowsteps were used to connect the deceased with the principal deities through metaphorical representation either as a ‘high place’ or as a ‘throne’. Secularly, crowsteps served basic human needs: representing identity, wealth and social structure. The study also considers that the Nabataean rock‐cut crowsteps activated the dialogue between different cultural traditions and helped in shaping the ideological cult and identity of the Nabataeans.     

The Bell-Tower Facade: An Aseismic Device in Sicily Between the 12th and 18th Centuries

Imposing tower facades with belfries in the last order were built in Sicily Italy, from the Middle Ages to the late Baroque period. Until the 16th century, this model, which was inspired by northern European examples, also had a parallelepiped forepart leaning against the facade, working as containment for the pressure imparted by the inner longitudinal arches on the front, and amplified in case of earthquakes. The lacking static efficiency of these early structures is demonstrated by collapses during the strong earthquakes that hit the island in the modern age. Despite numerous cases of destruction, the memory of some prototypes survived in Sicilian constructive memory through the elaboration, in the late Baroque, of tower facades with an updated morphology. The hybridization with Guarini’s pyramid scheme, and its related articulations, could in fact offer the tower system advantages in terms of structural strength, thanks to a better balanced redistribution of masses and weights.
