You ask where I think the name of May comes from?
Its origin’s not totally clear to me.
As a traveler stands unsure which way to go,
Seeing the paths fan out in all directions,
To give different reasons: plenty itself confuses….
[According to Ovid, the Muse Polyhymnia says that the month is named for the goddess Majesty (Maiesta); her sister Urania claims the month is dedicated to the Roman Senators (maiores), and another sister, Calliope, gives the honor to beautiful Maia, the mother of the god Mercury.]
“May. This month ranked second in the Alban calendar, third in that of Romulus, fifth in that of Numa. In the first-named calendar it was twenty-two days in length, thirty-one in that of Romulus, thirty in that of Numa, and thirty-one again in that of Julius Caesar. The name of this month is supposed by some to have come from Maia, the mother of the god Hermes, or Mercury. This, however, is based solely on the similarity of the two words, and the name of May was much more probably given in honor of the Majores or Maiores, the original Roman Senate… The Saxons called this month Tri-Milchi, the improved condition of the pastures now enabling the cows to give milk three times a day.”

Skipping by their fleecy dams.

Cassell’s Illustrated almanac 1871 for May.
Flowers —Tender plants may now be placed out of doors, and cuttings or seedlings may be removed from the frame to the ground in fine, showery weather. Propagate heartsease and wallflowers by cuttings, and plant out your dahlias in holes eighteen inches deep. Look carefully after your creepers, training the young shoots as soon as they get long enough, and cutting off badly-placed or untidy growths. You may make layers of fuchsias in the same manner as carnations, as soon as the stems are well grown, and they will be fine plants in the autumn.
Vegetables—Hoe well between your growing crops; and if you detect the presence of slugs or other insects, strew soot or lime round about the plants. Continue the sowing of beans, cabbage, lettuce, mustard and cress, &c.
Fruit—Regulate the shoots of trained trees, and continue to remove suckers. Check the growth on vines of young wood, which will, if neglected, absorb the strength of the trees, and prevent the fruit from coming to maturity. Cut off from strawberries all runners not required for propagation.
From the 1817 Almanac:
Sow cucumbers in the natural Ground, as also Purslane and Cabbages; sow Pease and Beans in a moist Soil for a latter Crop; plant Kidney-Beans for a second, Crop, and transplant Celery into Drills: How your Winter Crop of Carrots, Beans, Onions, &c. which will save much labour the succeeding Months. Sow Turnips, and, if rain comes soon after, it will very much encourage the Plant. Sow Buck-Wheat and latter Pease. Weed young Quicksets and Ivy; fallow your Ground; look well to your sheep, if the Weather proves wet, for fear of a Rot.

May. Limbourg frères. Grandes Heures of Jean, Duc de Berry, Fifteenth century. [unfortunately, the page, like that of april, got wet at some point]
The calendar pages of the Grandes Heures carried more religious symbolism than that of the more famous Très Riches Heures. Each month was dedicated to a part of the Apostles Creed, with the relevant prophecy from the Old Testament and scripture from the New Testament. May is dedicated to the article of the Creed which says “…He descended into Hell and the third day He rose from the dead…” Here we see (left to right) Saint Paul instructing the Ephesians (although the scripture “…rose again for our justification…” comes from Romans 4:25); Our Lady stands above the battlements of the New Jerusalem, holding a banner with a depiction of Our Lord descending into Hell; Gemini, the Twins, astrological symbol of May, emerges from the gate; the sun has moved into the fifth of twelve divisions in the arc of the sky; and below it, flowers are in bloom.
The Blessed Virgin Kneels before her Son, from “The Hours of Catherine of Cleves” 15th century.
April. Limbourg frères. Grandes Heures of Jean, Duc de Berry, Fifteenth century.
Depicted at the bottom of the calendar pages in the Grandes Heures is the fulfillment of the Law and the Prophets of the Old Testament by the articles of the Apostles Creed. In each, a prophet (cloaked to show the obscurity of prophecy) takes a stone out of the building representing the Old Law and offers it to an apostle, who, by raising the cloak ‘uncovers’ the prophecy with an article of faith. Here the Prophet Hosea (Osee) pulls another brick out of the edifice, from which more bricks are falling while a tower crumbles, and holds a banderole which translates to “…O death, I will be thy death, O hell, I will be thy bite…” (Hosea 13;14). Saint Thomas presents the relevant part of the Apostle’s Creed, “…He descended into Hell and the third day He rose from the dead…”
