Final answer:
The absence of a header course or the presence of weep holes in the brick may suggest that the masonry is a type of construction called post and lintel system which was common in ancient times.
Step-by-step explanation:
The absence of a header course or the presence of weep holes in the brick may suggest that the masonry is a type of construction called post and lintel system. Wood, brick, stone, or mud bricks were stacked and piled in this construction method, reaching the desired height and adding a lightweight roof made from wood. The post and lintel system utilized two pillars of stone and a third stone laid across them as the supporting structure.
However, this system was not suitable for very long spans, as it would collapse if the span were too high. This type of construction was common in ancient times, and many of the remaining buildings made of stone or brick have lost their roof structures due to the deterioration of the wood over time.
