The mahos’ agricultural activities mainly consisted of crop cultivation and livestock farming. Livestock products and unirrigated crops, almost exclusively barley, were complemented by terrestrial and maritime gathering. From livestock they not Orly obtained highly nutritious alimentary products, like milk and its derivatives and meat, but also skins, bones and tendons from which they manufactured various items, which in turn, served to transform other raw materials. The most common species of livestock were goats and sheep, well suited to the arid terrain. The growing of cereal in small plots, even though it was probably a customary practice among the first inhabitants of the island, may not have been a very profitable activity. EI Jable (pumice sand), natural cloud cover formed by the island’s central plain, retains atmospheric humidity, ensuring that cereal crops germinate and favouring the growth of pastureland grasses despite scarce rainfall. In this fertile area the main settlements are concentrated. Terrestrial gathering included the hunting of birds like shearwaters and pigeons, and the consumption of their eggs, together with the consumption of tree fruits, hmong them dates, high in sugar content. Other plants like patilla (aizoaceae), “cosco” (ice plant, a chenopodiaceae) and cerraja (sonchus herb) may also have been consumed at times of scarcity, as occurs in Berber populations. Marine gathering covered a wide range of species, of fish, like the parrotfish, but
above all molluscs, found in the island’s large “concheros” (shell deposits): limpets, sea snails, purpura, and sea urchins, the abundance of which suggests that seafood constituted an important dietary alternative for the majos. Lanzarote ceramics, handmade and very similar to those of Fuerteventura, shows characteristic shapes tending towards the spherical with flat base and wide spout, these known as tofios. Other receptacles are predominantly ovoid in shape with conic bases and trunco-conical with flat base. Appendages are generally not a feature, while the techniques applied to decoration involve incision, printing and grooving, forming motifs organised into strips of lines or points. Due to the absence of obsidian on the island, the stone tools of Lanzarote are made in basalt, and are of a similar type to those of the rest of the archipelago, consisting of chips, polishers, twopiece circular mills or one-piece navicular mills. There is also a set of objects made with chalcedony or calcite with a highly polished central groove, that are considered to be personal adornment items. The most common bone instruments are punches, generally made from long goat and sheep bones. Marine shells (conus, limpet or oyster) provide the material for a great number of items, generally found in burial sites, which are understood to have been used on clothing, as objects of personal adornment, and even as pendant amulets.
