Some fun facts about Lux iucunda, lux insignis, the Office of Readings hymn for Pentecost:
It's not actually a hymn! It was originally a liturgical sequence, ascribed to Adam of St. Victor. Originally 20 stanzas long, only stanzas 1, 2, 15, 18-20 were carried over. Adam's Salve dies, dierum gloria is another sequence that migrated into the office with the reform.
In medieval Paris, a different sequence was sung at each Mass of the octave of Pentecost, rather than singing Veni Sancte Spiritus every day, with Lux iucunda on Tuesday (the former wasn't sung until Saturday).
Today it's sung to the familiar melody of Lauda Sion Salvatórem, which actually took its melody from yet another of Adam's works, Laetabundi iubilemus.
Here is a book of verse translations of Adam's work, here is the website where I learned most of the above (It's French and I had to run it through Google), and here is a setting of Lux iucunda to a different melody, which I may try to sing.
