ALH is an acronym that stands for "Alkali Lintel Hypothesis." It refers to a scientific theory proposed by researchers in the field of archaeology and anthropology. The theory suggests that an alkali process was applied to the wooden lintels of ancient megalithic structures, such as Stonehenge, to enhance their durability and preserve them for longer periods.
According to the ALH, ancient builders soaked the wooden lintels in an alkali solution made from substances like animal fats, sewage, or urine. This process, combined with specific burial conditions and the elemental properties of the wood, is believed to have transformed the organic material of the lintels into a chemically stable and resistant substance, thereby preventing decay and degradation over time.
Proponents of the ALH argue that this hypothetical alkali process would explain why these wooden lintels have survived for thousands of years, despite the challenging environmental conditions and organic decay normally associated with wood. They believe that understanding and validating the ALH could provide valuable insights into ancient construction techniques and materials, shedding light on the technological advancements of past civilizations.
However, it is important to note that the ALH is still a hypothesis, and its validity remains a subject of debate and ongoing research. Scientists continue to investigate and analyze archaeological evidence to determine the extent to which the alkali treatment might have been employed in the preservation of megalithic structures.
