Luis is the second letter of the ogham alphabet, written ᚂ, and it is linked to the rowan tree. Of all the fews, Luis is the one most tied to protection, an association that comes straight from the rowan’s long place in folk tradition. This page covers the letter, the tree, and the meaning. For the whole alphabet see the ogham letters guide, and for every symbol’s meaning at a glance, the ogham symbols page.
The letter Luis
Luis is the second few in the first group, or aicme, and it is written as two strokes set to one side of the central line: ᚂ. Its sound is L. In the traditional order of the alphabet it follows Beith and comes before Fearn.
The rowan in Celtic tradition
The rowan, also called mountain ash or quickbeam, has one of the strongest protective reputations of any tree in British and Irish folklore. Rowans were planted beside doorways and gates to guard a home, and sprigs were carried or hung to ward off harm. Its small red berries, each marked with a tiny five-pointed star at the base, were treated as a sign of protection, and the tree was sometimes called the witch tree for its role in charms against ill luck.
This is genuine folk tradition, recorded across the Celtic world, and it is the root of everything the letter Luis is taken to mean today.
What Luis means in ogham
In modern ogham practice, Luis is read as protection and insight, a sign to shield yourself and to trust what your instincts are telling you. That reading grows naturally from the rowan’s folklore, though it is worth being clear that the detailed divinatory meanings are a modern development rather than something handed down from the druids. The tree and its protective reputation are old. The tidy one-line “meaning” is a modern layer. For how that applies across all the letters, see the ogham symbols and their meanings page.
Rowan in the Celtic tree calendar
Rowan is also one of the signs in the Celtic tree calendar, where it covers roughly January 21 to February 17. That calendar is a modern system, traced to the poet Robert Graves in 1948 rather than to ancient Celtic astrology, but it remains popular. If you were born in the rowan period, the Celtic tree calendar and find your birth tree guides cover the sign in full.

Luis is the rowan, also known as the mountain ash or quickbeam. It is a hardy tree with clusters of small red berries, and it holds a strong place in British and Irish folklore as a protective tree, planted by doorways and used in charms against ill luck.
Is rowan the ogham symbol for protection?
