Geography/Culture: Celtic: Gauls.
Linguistic Note: the derivation of the word rosemary (as in the herb) is from Latin ros, 'dew', and marinus, 'the sea'; however -merta, might be from the Latin stem merx, 'merchandise', relating to Her connection with the Gallic Mercury, or even connected with Latin meretrix, 'a courtesan'.
Note: Little or nothing of Rosmerta appears to be known, other than Her name, {Dew-of-the-Sea}, and some images of Her standing with the Gallic Mercury. Therefore I take what information I can find on Roman Maia, Grandmother, with whom She is most commonly identified, and give it to Rosmerta, {Dew-of-the-Sea}.
Description: Scowling Goddess of fire, wealth and material abundance; Ruler of the forces of warmth and growth; (perhaps) once Mistress of the night-sky; Ever fair and young Queen of flowers; Malevolent Beldame of death; Hater of marriage.
To Whom Sacred: rosemary, for remembrance, fidelity and friendship frequently used as funeral wreaths (for a pun on Her name); {hawthorn (if Her association with Maia is correct)}; perhaps tortoise (which is appears between the feet of Her and Her consort in the images); cornucopia (which She bears in Her left arm in Her images); the month of May (unlucky for marriage); the Pleiades (because they rise in May and because Greek Maia is one of them); some unidentified, but clearly man-made object which She holds in Her right hand in Her images).
Festival: perhaps the Rosalia, MAY 21-23, when tombs of the dead were strewn with roses, may be suitably given to Her by punning on Her name, and Her association with May and the dead.
Male Associates: consort: the Gallic Mercury, probably meaning Wotan.
