Piece of chant sheet music

[Trazom H Cab]

I bought this piece of sheet music from 1500 that appears to be chant but it has 5 staff lines instead of 4.  The three-diamond clef doesn't look like the fa-clef and indeed may be something else entirely.

The three-diamond clef is odd. It doesn't look like the normal Fa clef but I suppose that's what it must be.  Also, what are the marks that look sort of like check marks or meerschaum pipes?

It took some puzzling it out but the words read:

"Custodi me domine ut pupillam oculi sub umbra alaru tuarum protege me."

I typed that into Google and it seems I have a typo. The phrase should read:

"Custodi me domine ut pupillam oculi sub umbra alarum tuarum protege me."

There is a missing "M" for some reason.

It's part of Psalm 16:5-9. From the Vulgate:

"Perfice gressus meos in semitis tuis, ut non moveantur vestigia mea. Ego clamavi, quoniam exaudisti me, Deus. Inclina aurem tuam mihi, et exaudi verba mea. Mirifica misericordias tuas, Domine, qui salvos facis sperantes in te. Custodi me, Domine, ut pupillam oculi. Sub umbra alarum tuarum protege me a facie impiorum qui me afflixerunt. "

Or:

"Keep my steps steadfast in Thy paths, that my footsteps may not falter. I have cried to Thee, for Thou, O God, hast heard me. Incline Thy ear unto me, and hear my words. Shew forth Thy wonderful mercies; Thou who savest those who hope in Thee. Guard me, Lord, as the apple of Thy eye. Protect me under the shadow of Thy wings from the face of the wicked who have afflicted me."

It's part of the Psalter of St. Jerome.

I do not know what the preceding sentence fragment at the beginning of the document is from. Perhaps one of you religious folk would know.  I also wonder if this chant has been recorded already. Any ideas?

[Luke]

The clef is the early mensural  form of the C clef (you can see it here https://commons.wikimedia.org/wiki/File:Mensural_c_clef_02.svg and its evolution to the modern form here https://commons.wikimedia.org/wiki/File:C_clef_evol.JPG - there are similar evolutions for the G and F clefs too). The 'pipe' is a mensural notation for a slide from a lower note to a higher, unfortunately its a long time since I studied this stuff and I've forgotten its technical name!

[Luke]

sorry, didn't read your post properly. Yes the 'three diamond' clef is an F clef. Your first imageis the end of a chant using a C clef and the beginning of one using an F, but you obviously knew that anyway.

Thank you, Luke.

The whole chant reads: "The kings of Sheba and Seba shall bring him gifts, Alleluiah. All those from Sheba shall come, alleluiah, alleluiah. They shall bring gold and frankincense. Before you, O God, all the earth shall bow, shall sing to you, alleluiah, alleluiah."
