        The schist village of Piod�o has long been a 
    popular place for Portuguese to visit. 
         
        The discovery of numerous nearby examples of bronze-age 
    rock-art, 
        
    cart-ruts, 
    and several 
        
    spirals, 
    (of which the photo on the right is the largest),  
    has greatly re-enforced the value of visiting the area.

    The Spiral
    
    - This giant example of 
    spiral-art was recently discovered near Piod�o. The 
    discovery of numerous other examples of rock-art, or 'Arte 
    rupestre',  in the same  area (including several other spirals),  elevates 
    the potential significance of this location on the megalithic landscape. 
    This spiral is carved on a 
    stone 
     
    over a metre long, which appears to be still attached to the bedrock. The 
    top surface looks as though it may have been 'worked' into its 
    parabolic form,  although it is equally likely that it is a natural formation, 
    and might even be the reason for selecting this stone. It looks as though the 
    design on top is still complete, having been carved onto the rock in the 
    same shape we see it today. 
    There are two or three cup-marks on the rock and on the rock next to it, 
    which looks as though the front half of it has collapsed on the ground in 
    front of it. One wonders whether there might be other carvings on the face 
    down part of the rock. 
    
     The design on the stone 
    consists of a spiral which continues to become an 'animal' figure (which has 
    been suggested as being a horse), then continues to zig-zag up and down the 
    rock several times, before forming another shape (as yet unidentified), then 
    zig-zags up and down again several more times before ending (or possibly starting) at the top of the rock in a 
    distinct cup-mark.    
				   
					
						The 'Horse' 
    - This feature has been suggested as being a horse, in 
    relation to the name of the site which is the 'Vale d'eguas', or 'valley of the
						mares'.      
			 The 
    		'Footprint'. On the rear of the stone is a 'foot-print' shaped 
    motif (See right), a symbol which is found on several other stones in the region. The same area has produced over 50 
    examples of rock-art, seemingly scattered around on the rocks, however, their abundance in such 
    an isolated location , as well as the proximity  of many of the 
    carvings to the cart-ruts, known locally as 'strada's real', or 
    'royal roads', make it likely that the area had some significance in the 
    past. The presence of carved 'feet' and carved crosses, is suggestive of a 
    ceremony.   The association between these two symbols has 
    been noticed before by Paturi 
			(1), who suggested that the carved 'feet' 
    are evidence of marriage ceremonies, and that the crosses signified the 
    later 'Christianisation' of such areas.   
				
    			
				
    
      
			 Extract 
    from Paturi (1)
			
			: 'On the
    Hexenstein the witches stone near Terenten... which was most certainly 
    also a fertility rock, our Bronze age ancestors did not carve just cup forms 
    onto the rock. It is also possible to distinguish quite clearly the imprint 
    foot chiselled into the stone. 
    In places this symbol on the rock carvings is relatively frequent'. Paturi 
    continues 'Various scholars of prehistory have given different 
    interpretations of the foot imprints'. He then quotes Karl Lukan, who 
    maintained that the footprints are those of brides and were chiselled at the 
    marriage ceremony. 'They were in fact marriage documents made of stone'.  Interestingly, Paturi then 
    says 'these rites were often preserved for centuries, which was a thorn in 
    the flesh of the Christian church...The church endeavoured, often 
    unsuccessfully, to wean its lambs from the worship of pagan deities...They 
    decided to combat ancient magic with newly invented magic using the sign of 
    the cross to banish witches and evil spirits'. 
			 
    
        
    
        The cross in the photo 
    (above, left), was also found carved into a rock at Piodao.

     The 
    Piodao Cart -ruts - 'Strada's 
    Real'. 
    
    
    
    
    As Well as 
    the numerous examples 
    of rock-art, Piodao also has a good example of
    
    
         cart-ruts or 'Strada's 
    real', running 
    along the hill-tops close by. Unlike the
    
    
        
    Maltese cart-ruts 
    however, these are traditionally associated with pilgrimage. 
    
       
    
    These ruts were apparently used until relatively recently, however, their 
    antiquity is indicated by the many examples of prehistoric rock art or 'arte rupeste' 
    found alongside the ruts.
