* Gavrinis *and

*are very similar monuments, both in the*

**Tables des Marchands****orientation of their passageways**and their

**identical latitude**.

*Gavrinis*is about

**3900 metres**east of

*Tables des Marchands*but, unlike the latter, has a Breton name based upon the root

**GVR**(gower). Both passageways directly express the difference between the winter solstice sunrise and the lunar maximum moonrise to the South, by designing the passages to allow these luminaries to enter at the

**exact day**of the winter solstice or

**the most southerly moonrise**over many lunar orbits, during the moon’s maximum standstill. Thus both the monuments

**allow the maximum moon along their passageway**whilst the

**winter solstice sunrise**

**can only glance**into their end chambers.

From Howard Crowhurst’s work on multiple squares, we know that this difference in angle is that between a **3-4-5 triangle** and the **diagonal of a square** which is achieved directly by the **diagonal of a seven square rectangle**.
